Abstract

The present research was conducted to measure the impact of poppy seed extract (PSE) and gamma irradiation on the storage stability and antioxidant profile of beef patties during storage at different packaging. Different doses of gamma irradiation (2.5 kGy and 5 kGy) were applied alone and with combination of 2% PSE. The PSE enriched beef patties were packed (aerobically and vacuum) and kept at refrigeration temperature. The results show that higher value of TBARS and POV was found in 5 kGy aerobically packed samples at 14 day, while the lower value of TVBN was observed in 0 kGy+PSE2% at 0 day. However, the lower value of TBARS, POV and TBVN was found in vacuum packed samples (0kGy +2%PSE) at 0 day. The higher total phenolic contents, ferric reducing antioxidant power and DPPH value were found in 0kGy +2%PSE and lower value was found in samples (5 kGy). The microbial results were observed to decrease with the increase in dose of gamma radiation. The significant changes were observed in the hunter color and sensory attributes of beef patties on different treatment at storage intervals under vacuum and aerobic packaging. Conclusively, PSE, gamma irradiation and both packaging is improved the quality, stability and antioxidants profile of enriched patties.

ABSTRACT
The present research was conducted to measure the impact of poppy seed
extract (PSE) and gamma irradiation on the storage stability and antioxidant
prole of beef patties during storage at dierent packaging. Dierent doses
of gamma irradiation (2.5 kGy and 5 kGy) were applied alone and with
combination of 2% PSE. The PSE enriched beef patties were packed (aero-
bically and vacuum) and kept at refrigeration temperature. The results show
that higher value of TBARS and POV was found in 5 kGy aerobically packed
samples at 14 day, while the lower value of TVBN was observed in 0 kGy
+PSE2% at 0 day. However, the lower value of TBARS, POV and TBVN was
found in vacuum packed samples (0kGy +2%PSE) at 0 day. The higher total
phenolic contents, ferric reducing antioxidant power and DPPH value were
found in 0kGy +2%PSE and lower value was found in samples (5 kGy). The
microbial results were observed to decrease with the increase in dose of
gamma radiation. The signicant changes were observed in the hunter color
and sensory attributes of beef patties on dierent treatment at storage
intervals under vacuum and aerobic packaging. Conclusively, PSE, gamma
irradiation and both packaging is improved the quality, stability and antiox-

Introduction
Ground beef patties are the most popular beef products for consumers preparing meals at the
home. The limited shelf life of fresh ground beef has less than 7 days in ordinary refrigerators
that can protect it from microorganisms spoilage. Pseudomonads and lactic acid are two
bacteria that are recognized as the main spoilage microbes. They can initiate the deterioration
of chilled or stored minced beef.
[1]
Beef meat is categorized as highly valuable food, and it
comprises minerals such as zinc and selenium and also contains B complex vitamin. The food
products that are easily prepared and ready-to-eat food items are increasing with the demands,
and on another hand the major, concerns for food security and safety also increasing quality.
Lipid peroxidation is one of the important key factors in meat that affects meat acceptability.
It decreases the meat freshness and also affects its color. Lipid peroxidation in beef not only
reduced meat value but also produced other free radical that causes mutagenesis, inflamma-
tion, cardiovascular disease, aging and carcinogenesis. Therefore, it is necessary to reduce lipid
peroxidation arising from natural resources.

which unsaturated fatty acid makes the section of membrane phospholipids. Furthermore,
oxidized are sensitive in the oxidation of meat due to more unsaturated fatty acids as
compared to other lipids. However, the level of oxidative degradation can be decreased by
manipulation with natural antioxidants which preserve lipids from oxidation and secure ox-
myoglobin. There is a significant increase in utilization of antioxidants to reduce the chemical
deterioration of meat products. The antioxidants obtained from plants can be combined with
meat or meat items during processing. Ascorbic acid has antioxidant properties that can be
used in meat products to preserve basic quality.

Poppy (Papaver somniferum) is an ornamental plant that is cultivated all over the world.
The poppy seeds (Papaver somniferum) are a multiuse yield that is utilized in pharmaceutical
purpose, bakery and confectionary products and seed oil.
[4]
Poppy seeds have high antioxidant
activity.
[5]
Although alkaloids from poppy capsules and straw are generally used in the
pharmaceutical industry, whereas its seeds are used largely in various baked products.
[6]
In
addition to alkaloids, phenyl propanoids flavonoid capacity in poppy seed extracts was
identified by.
[7]
A recent study suggests that poppy seeds can be used as food and to produce
edible oil.
[8]
Previous studies showed that poppy seeds were incorporated into the different
types of meat products as a fat replacer and antioxidants.
[9,10]
The newly developed technol-
ogies make assured the microbiological safety of meat with radiation handling.
[11]
Food
irradiation eliminates the microbial population from food that are injurious for human health.
It is the physical procedure involving the handling of foods between ionizing radiation.
[12]
The
effects of the combined treatment of turmeric powder and irradiations in chicken meat and
observed that with the increase in gamma radiation dose, the microbial load decreases.
Composition of gamma rays and bioactive composite is helpful in increasing the stability
and quality of chicken as well as its products. It can also be useful for bringing down the
quantity of gamma rays.
[13]
Gamma rays (GR) are mostly used in commercial plants to handle pre-packed products due to
high penetrating power. However, electron beam (EB) has limited penetration power and depth
only up to 8 cm in food. The low dosage of gamma radiation (3 kGy) are helpful in instantly the
shelf life of ground beef by reducing the growth of microbes. The 3 kGy gamma radiation dose
would reduce 99% of bacterial loads (Salmonella spp., and Listeria spp.,) from meat products as
well as from ground beef.
[14]
The main objective was to minimize the quality loss of beef patties as well as enhancing the
antioxidant profile of poppy seed extract enriched beef patties during storage. The significance of
this study shows that the combination of poppy seed extract and irradiation increased the shelf
stability of beef patties at different storage and packaging.
Materials and methods
Procurement of materials and preparation of samples
All the raw materials including beef and poppy seed were procured from local market of Faisalabad,
Pakistan. The chemicals and glassware are purchased from Sigma-Aldrich®, USA. Poppy seeds were
sun dried for one day and then crushed to form fine powder by means of grinding machine. After that
grinding powder was preserved in air tight bags to prevent moisture gain prior to extraction. Patties
were formed when beef was thawed and minced.
Extraction of PSE and solvent ltration and evaporation
Poppy seeds powder was put in 500 ml beaker with 70% ethanol at 1:10 solid to solvent ratio. The
extract was carried out at room temperature for 10 min.
[15]
The extractions were clarified by using
Whatman No.1 filter paper. The filtrate of all samples were evaporated with a rotary evaporator

attached with a vacuum pump and a frozen cooling system. All solvent was dried in water bath at high
temperature (79°C) and vacuum pressure (0.07 MPa).
Development of beef patties
Ground beef weighed (100 g of each) and shaped into patties. The extract with different concentration
was added to beef patties and then patties were stored in airtight plastic bags at refrigeration
temperature.
Gamma irradiation
Gamma irradiation was applied at Nuclear Institute for Agriculture and Biology, Faisalabad, which is
under the Pakistan Atomic Energy Commission. There were total six samples with vacuum and
aerobic packaging. Two doses of gamma irradiation (2.5kGy and 5kGy) were used alone and with
combination of poppy seed extract (2%).
Physical analysis
Hunter color (Lab)
The PSE enriched beef patties surface color was evaluated by Hunter colorimeter, with respect to
calibration plate (L = 89.2, a = 0.921and b = 0.783). The CIE L (lightness), CIE a(redness) and CIE
b (yellowness) color values were evaluated and examined statistically. The Hunter color of beef patties
was measured according to the method of American Meat Science Association.
[16]
Antioxidant prole
Determination of total phenolic contents (TPC)
Total phenolic content of enriched beef patties was evaluated by spectrophotometric with using Folin-
Ciocalteu reagent.
[15]
Briefly 1 ml of 10% Folin-Ciocalteu reagent was added to 0.5 ml of a recognized
concentration of a sample. The mixture was left for 6 min after mixing well and then add 2 ml of 20%
sodium carbonate solution in the above mixture. At 760 nm the phenols were measured for 60 min at
30°C using the spectrophotometer after reacting. A standardized bend was set using standard solution
of gallic acid and the results of total phenols was expressed as 1 g of gallic acid equivalents (GAE) per
gram of sample.
DPPH (2,2-diphenyl-1-picrylhydrazyl) scavenging assay
DPPH is a firm extremely colored free radical that can abstract labile hydrogen atoms from phenolic
antioxidants with related shape of a colorless hydrazine (DPPH-H|).
[17]
The scavenging activity of free
radical (FRSA) of the PSE enriched patties was determined according to the technique explained by
the
[18]
with some changes. Using spectrophotometer homogenized sample of 0.1 ml was added in
freshly prepared at 517 nm. The total FRSA of each sample was expressed as the % age of DPPH
decreased and calculated as follows: FRSA = 100-(initial absorbance – final absorbance)/initial absor-
bance. The absorbance values of the initial and final absorbance are of DPPH at time zero and after 60
min respectively.
Ferric Reducing Antioxidant Power (FRAP) Assay
Homogenized sample of 10 µl was added to 30 µl of distilled water and 300 µl of FRAP reagent at room
temperature. After that the following solution was incubated for 5 min. After the power of the blue

hued complex formed at that point was expected spectrophotometrically utilizing Jenway UV-Vis
Spectrophotometer at 593 nm. The FRAP reagent was prepared by mixing 25 ml of acetate buffer (300
mM Sodium acetate at pH 3.6) and 2.5 ml of TPTZ (10 mM 2,4,6-Tripyridyl-s-triazine in 40 mM HCl)
with 2.5 ml of Ferric chloride solution (20 mM FeCl3.6H2O in distilled water). FRAP reagent was
warmed at 37°C and prepared fresh before use. The decreasing intensity of each sample at that point
was determined as equal to that of 1 mM of Fe (II) (FRAP unit). All the samples were analyzed in
triplicates (n = 3).
[19]
Physiochemical analysis of PSE patties
Total Volatile Basic Nitrogen (TVB-N)
The TVBN was performed according to the Conway micro-diffusion method described by
Pearson.
[20]
Samples were mixed with trichloroacetic acid (TCA) in the quantity of 1:2 (w/v)
and homogenized using mixer (Waring Commercial Blender, USA). The samples were cen-
trifuged (3000 rpm for 5 minutes) and filtered through Whatman No.1 channel paper. The 5
ml of 10% sodium hydroxide was added to the mixture. Steam cleansing was performed using
distillated. Until the shade turns pink the distillate was titrated against 0.05 M sulfuric
corrosive.
Thiobarbituric Reactive Substances (TBARS)
The 2-thiobarbituric reactive substances values were measured according to the method of
Schmedes et al.
[21]
with few modifications. The 5 g sample was mixed with 25 ml of 20%
trichloroacetic acid (200 g/L) in 135 ml/L phosphoric acid solution in a homogenizer for 30
s. The homogenized samples were separated through Whatman filter paper number 4 to dispose
of solid particles from the filtrate. 2 ml of 0.02 M watery TBA arrangement (3 g/L) was added to 2
ml filtrate in a test tube at point. The cylinders were incubated at 100°C for 30 min and cooled in
running tap water. The absorbance of supernatant solutions was estimated at 532 nm utilizing UV-
VIS spectrophotometer. Standard curve was determined the TBA and communicated as mg

factorial under CRD. The means were compared by using LSD.
Results and discussion
The present research was intended to the impact of different doses of gamma irradiation and poppy
seed extract (PSE) for exploitation as a preservative and antioxidant in beef patties. Afterwards impact
of various combinations of gamma irradiation and poppy seed extract were analyzed on the sensory
and quality characteristics of beef patties. It was contrived at various levels (0kGy, 2.5kGyand 5kGy) of
gamma radiation in combination with poppy seed extract (2%). The PSE enriched beef patties were
assessed physically (Hunter colorimeter), physicochemical (TBARS, POV and TVBN), functionally
(DPPH, FRAP, and TPC). Microbial analysis was done by TBC and Coliform. Beef patties were
significant effects of TBARS, POV and TBVN value on treatments, packaging and storage interval.
Thiobarbituric acid reactive substances (TBARS)
TBARS are formed as a by-product of lipid peroxidation. Malondialdehyde (MDA) is a reactive

regarding the TBARS value of PSE beef patties with different storage intervals. Beef patties have
significant effects of TBARS value on treatments, packaging and storage interval. The results depicted
that the higher value of TBARS (0.49 ± 0.03MDA/kg) was found in samples treated with (5 kGy
+PSE2%) aerobically packed samples on 14 days storage interval. However the (Table 1) represents
that the lower value (0.22 ± 0.04 MDA/kg) was found in the vacuum-packaged sample (0 kGy
+PSE2%) on 0 day of storage interval. Irradiation is a method of meat preservation and possess
excellent potential to improve and enhance meat safety and extend shelf life of meat. Poppy seed
extract has antioxidant properties which slows down the mechanism of oxidation. Ham et al.
[26]
conducted a study who examined that the beef patties had higher values of TBARS when treated (10
kGy) on 0 day storage time. On the other hand, Brewer,
[27]
stated that the results of TBARS values was
increased in beef meat when treated with 1.25 kGy gamma irradiation on 7 days of storage time.
Meanwhile, Rababah et al.
[28]
examined that the results of TBARS values were increased in chicken
breast meat when treated with irradiation for 0 − 12 days of storage at 5°C. In another study examined
that a high amount of TBARS in the irradiation dose in vacuum-packaged beef sausage patties on 10
days of storage period.
[29]
Rima et al.
[30]
examined that the raw broiler meat had higher values of
TBARS when treated (3.5 kGy) at 60 day storage time. The outcomes of this study also depicted that
with the increase in storing interval, the amount of TBARS was increased. An et al.
[31]
who examined
that the smoked duck meat had maximum values of TBARS when treated (4.5 kGy) on 40 day storage
period, while a minimum value of TBARS was analyzed in untreated samples. Our findings showed the
similarity with the Arshad et al.
[13]
who reported the impact of turmeric powder and gamma
irradiations in chicken meat and examined that the chicken meat had higher values of TBARS when
treated (2 kGy) in aerobically packed samples on 14 days storage period, while a minimum value was
analyzed in untreated samples. Kamal et al.
[32]
depicted that the TBARS value of crushed poppy seed
paste addition in chevon nugget. The TBARS value was minimum as compared to untreated chevon
nugget. The recorded TBARS value depicted that the untreated chevon nugget was spoiled and was not
suitable for human intake till 21st day of refrigeration storage. Moreover, poppy seed paste enriched
chevon nugget was analyzed to be fit for human intake even on 21st day of refrigeration storage.
Peroxide value (POV)
The statistical results regarding the POV value of PSE beef patties were significant effect with respect
to treatments, packaging and storage interval as showed in Table 2. Higher value of POV (0.53 ± 0.01

kGy on day 0. Poppy seed extract contains natural anti-oxidants which limits the mechanism of lipid
oxidation. The results depicted that the peroxide value was lower in vacuum packed beef patties
samples as compare to aerobically packed samples. Arshad et al.
[33]
conducted a study on frozen duck
meat that was treated with 0, 3 and 7 kGy at the storage period. The higher finding of POV was
observed at the end of storage and on high dose of E-bean. Arshad et al.
[13]
depicted that POV values
were increased significantly with 14 days storage interval in broiler meat. Although with the higher
irradiation doses POV values in aerobic and in vacuum packaging also increases. On the other hand,
when samples treated with moringa leaf powder the POV values decreases. Rima et al.
[30]
depicted that
POV values were increased significantly in broiler meat with higher irradiation doses treated with
(2kGy) as well as storage time of 30 day. Dzudie et al.
[34]
stated that POV value significantly increases
with 10 day storage interval although the beef patties treated with 0.2% of ginger essential oil had
shown reduction in lipid oxidation. The results indicated that the treated beef patties sample had
a minimum value in vacuum packaging and maximum peroxide value in treated samples. Our results
are in agreement with the results of Kim et al.
[35]
who declared with the increase in dosage of gamma
radiation and increase in storage period POV also increases.
Total volatile basic nitrogen (TVBN)
The statistical results regarding the TBVN value of PSE beef patties with different storage intervals are
given in Table 3. Beef patties results were significant effects of TVBN value on treatments, packaging,
and storage interval. The results depicted that the highest value of TVBN (12.56 ± 0.39 mg/100 mL)
was analyzed in (0 kGy) aerobically-packed beef patties samples on 14 day of storage period, followed
by vacuum-packaging fresh beef patties samples at (0 kGy) showed the value (12.96 ± 0.41 mg/100 mL)
on 14th day of storage interval. However, the results depicted that the lowest value (8.03 ± 0.24 mg/
100 mL) was analyzed in the vacuum-packaged beef patties samples treated with (0 kGy+ PSE 2%) on
0 day of storage interval. The results portrayed that the TVBN value in vacuum-packaged beef patties
samples significantly decreased as compared to aerobically packed beef patties samples. Moreover, the
TVBN value in raw beef patties samples (control) become higher with the increase in storage period,
while irradiated beef patties with poppy seed extract and without poppy seed extract suppressed the
higher TBVN value with the storage period. By the addition of poppy seed extract, the TBVN value
decreased in both the aerobically packed beef patties and vacuum packed beef patties samples. The
results designated that the treated (0kGy +2%PSE) samples of beef patties have a minimum value of
TVBN in vacuum packaged samples, whereas maximum value of TVBN was analyzed in treated beef
patties samples, which are in reliable with the results of
[13]
who reported that the total volatile basic
nitrogen content was found higher with the increase in storing time but irradiation treatment controls
the development of TVBN during storage time. Minimizing the level of bacteria and by enhancing the

[36]
who examined that the TVBN value was higher at the start of the storage duration However, different
irradiation doses significantly suppressed TVBN value during 12 days of storage interval. These
findings showed that higher the dose of irradiation lower the rate of TVBN formation during storage
period by reducing the levels of spoilage microorganisms. Li et al.
[15]
depicted that the volatiles
substances become higher in amount with the increase dose of irradiation in pork samples as
compared to lower dose irradiated samples during storage interval. Ahn et al.
[37]
stated that increase
in TVBN level by irradiation process may be due to the breakdown of nitrogenous complexes/
compounds present in meat samples. An et al.
[31]
reported that, TVBN had maximum value at
0-day storage without the radiation treatment but the minimum value of TBVN was in irradiated
samples Our findings showed the similarity with
[38]
who depicted that TVBN value in chicken meat
untreated samples become higher with the increase in storage period, while irradiated chicken samples
with moringa leaf powder reduced the higher TBVN value with the storage period. By adding moringa
leaf powder the TBVN value decreased in both the aerobically and vacuum packed chicken meats
samples. Our outcome is related to Yun
[39]
who stated that volatile compounds were enhanced by the
ionization process in ready-to-eat chicken breast, whereas TVBN values were formed slowly as
compared to unirradiated meat at the time of storage. However, another study showed that volatile
substances were found to increase in pork meat when subjected to a high dose of irradiation.

DPPH (2,2-diphenyl-1-picrylhydrazyl)
The statistical results regarding the DPPH value of PSE beef patties with different storage intervals are
given in Table 4. Beef patties had significant effects of DPPH value on treatments, packaging and
storage interval. The results depicted that the higher value of DPPH (72.54 ± 2.935%) was found in
samples treated with (0 kGy + 2%PSE) vacuum packed samples on 0-day storage However, the
outcome represents that the minimum value (48.52 ± 1.00%) was found in the aerobically-packaged
samples treated with (5 kGy) on 14 day of storage interval. The results showed the higher value of
DPPH in vacuum packed beef patties samples and lower value in aerobically packaged beef patties
samples. Furthermore, with the increase in storage time, the DPPH value in untreated (control) beef
patties samples also decreased. With the addition of (PSE) poppy seed extract, the DPPH value
increased in aerobically packaged beef patties samples as well as in vacuum packaged samples. The
result depicted that the treated beef patties samples had a lower value of DPPH in aerobically packaged
beef samples, while a higher value of DPPH was found in untreated (control) beef patties samples. Our

Total phenolic content (TPC)
The statistical results regarding the TPC value of PSE beef patties with different storage intervals are given
in Table 5. Beef patties results had significant effects of TPC value on treatments, packaging, and storage
interval. The results depicted that the highest value of TPC (127.14 ± 3.93 mg/g GAE) was observed in (0
kGy + 2%PSE) vacuum-packed beef patties samples on 0 day of storage period, followed by aerobically-
packaging of beef patties samples at (0kGy +2%PSE) showed the value (124.32 ± 3.31 mg/g GAE) on 0 day
of storage interval. However the results depicted that the lowest value (92.52 ± 1.89 mg/g GAE) was
analyzed in the aerobically-packaged beef patties samples treated with (5 kGy) on 14 day of storage
interval. The results portrayed that the TPC value in vacuum-packaged beef patties samples significantly
increases as compared to aerobically packed beef patties samples. Furthermore, the TPC value in untreated
beef patties samples (control) decreases with the increase in storage period, while irradiated beef patties
with poppy seed extract and without poppy seed extract suppressed the higher TBVN value with the
storage period. By the addition of poppy seed extract, the TPC value increased in both the aerobically
packed beef patties and vacuum packed beef patties samples. The results designated that the treated (0kGy
+2%PSE) samples of beef patties have a higher value of TPC in vacuum packaged samples, whereas lower
value of TPC was analyzed in treated beef patties samples aerobically packed. Moreover, Ergezer &
Serdaroğlu
[42]
reported that the total phenolic content of all the raw beef patties samples decreased
significantly by the expansion in storage interval. Our findings showed the similarity with the results
of
[31]
who stated that the TPC value significantly increased in vacuum packaged samples as compare to
aerobically packed samples. Sharma & Bhat
[43]
depicted that during the storage time TPC total phenolic
content significantly decreased in raw chicken sausage products at each interval of storage duration.
Ferric Reducing Antioxidant Power (FRAP)
To evaluate the total antioxidant content of a sample, the ferric decreasing/antioxidant power

Total aerobic bacteria and coliforms count
The statistical results regarding the total aerobic bacteria and coliform value of beef patties with
different storage intervals are given in Table 7. The treated samples with PSE extract and gamma
radiation were analyzed regarding to coliform count and total aerobic bacteria. The results depicted
that the bacterial load/microbial population decreases with increased dose of gamma radiation.
Moreover, bacterial contamination increased in aerobic packaging and decreased in vacuum packa-
ging. The results indicated that the higher bacterial count of (11.28 ± 0.37 log CFU/g) of total aerobic
bacteria was analyzed in control samples (0kGy) in aerobically packaged samples on the 14
th
day of
storage interval. The lower total bacterial count (2.88 ± 0.16 log CFU/g) was analyzed in (5kGy gamma
radiation + PSE 2%) vacuum packaged samples on 0

Hunter color (Lab)
Hunter L, a, b scales are created on the basis of Opponent-Color Theory. This theory accepts that the
receptors in the human eye distinguish color as the following pairs of opposites. The L value indicates the
level of light or dark, a value redness or greenness, and the b value yellowness or blueness. All three values
are required to completely describe an object’s color. The statistical results regarding the color parameter
of PSE beef patties are shown up in Table 8. The outcomes depicted that the L* value of beef patties have
significant effects with respect to treatments, packaging and storage interval. The outcomes depicted that
the higher value of L* (59.76 ± 3.75) was analyzed in those beef patties samples treated with (0 kGy + 2%

represents that the minimum L* value (50.40 ± 2.53) was analyzed in the vacuum-packaged samples
treated with (2.5 kGy + 2%PSE) on 14th day of storage interval. The results depicted that L* value
decreased significantly in vacuum packed beef patties samples as contrast to aerobically packaged samples.
Furthermore, with the passage of time the L* value in (control) trials increased. With the addition of
poppy seed extract, the L* value increased in aerobically packaged samples and vacuum packaged

analyzed in the vacuum-packaged samples on 14
th
day of storage interval. The outcomes depicted that
b* value decreased significantly in vacuum packaged beef patties samples as contrast to aerobically
packaged samples. Moreover, the b* value in untreated (control) samples decreased with the passage of
time. With the addition of poppy seed extract, the b* value increased in aerobically packaged samples
and vacuum packaged samples. The results depicted that treated beef patties samples has maximum
value in aerobically packaged samples, while minimum value was analyzed in vacuum packaged treated
beef patties samples. Our findings showed the similarity with the findings of An et al.
[31]
who reported
that with the increase in dose of gamma radiation (0 to 2kGy), the b* value of gamma irradiated chicken
meat also increases. In another study Rima et al.
[30]
stated that higher the dose of gamma radiation (0 to
4.5kGy) was changed the b* value of gamma irradiated smoked duck meat. Our results are in line with
Nam et al.

The results regarding the myoglobin content of PSE beef patties samples which are significantly
affected by with treatments, packaging and storage interval as showed in Tables 4–9. The results
indicated that the maximum amount of (Mb) myoglobin (45.98 ± 2.23%) content was analyzed in
samples treated with (0kGy +2%PSE) in vacuum packaged beef patties samples on 0 day of storage
period, followed by aerobically packaged beef patties samples treated with (0kGy +2%PSE) showed the
value (44.89 ± 2.45%) on 0 day storage whereas, the lower value of Mb content (28.09 ± 2.18%) was
analyzed in vacuum packaged beef patties samples treated with (2.5kGy +2%PSE) on the 14

storage period as shown in Table 9.The outcomes depicted that the myoglobin content decreased
significantly in vacuum packaged beef patties samples as compared to aerobically packed samples.
Furthermore, the myoglobin content of untreated (control) beef patties samples reduced gradually.
With the addition of poppy seed extract, the myoglobin content increased in aerobically packed
samples as well as in vacuum packaged samples. The outcomes showed the higher amount of (MbO2)
oxymyoglobin (20.90 ± 0.32%) content was analyzed in samples treated with 2.5kGy in aerobically
packaged beef patties samples on 14th day of storage period, followed by vacuum packaged beef patties
samples treated with 2.5kGy showed the value (19.06 ± 0.725%) on 14
th
day storage whereas, the lower
value of MbO2 content (9.38 ± 0.21%) was analyzed in vacuum packaged beef patties samples treated
with (2.5kGy+PSE 2%) on the 14
th
day of storage period. The findings depicted that the oxymyoglobin
content decreased significantly in vacuum packaged beef patties samples as compared to aerobically
packed samples. Moreover, with the passage of time the oxymyoglobin content of untreated (control)
beef patties samples increased. With the addition of poppy seed extract, the oxymyoglobin content
decreased in aerobically packed samples as well as in vacuum packaged samples
The results showed that the higher amount of (MMb) metmyoglobin (66.11 ± 4.05%) content was
analyzed in samples treated with (2.5KGy)in aerobically packaged beef patties samples on 14th day of
storage period, followed by vacuum packaged beef patties samples treated with(2.5kGy) showed the
value (62.26 ± 4.02%) on 14
th
day storage whereas, the lower value of MMb content (40.69 ± 2.13%)
was analyzed in vacuum packaged beef patties samples treated with (0kGy+PSE 2%) on the 0
th
day of
storage period as shown in Table 9. The outcomes indicated that the metmyoglobin content decreased
significantly in vacuum packaged beef patties samples as compared to aerobically packed samples.
Furthermore, with the passage of time the metmyoglobin content of untreated (control) beef patties
samples increased. With the addition of poppy seed extract, the metmyoglobin content decreased in
aerobically packed samples as well as in vacuum packaged samples. The findings depicted that the
treated beef patties samples have minimum myoglobin content in aerobically packaged samples,
whereas in oxymyoglobin and met myoglobin minimum content were analyzed in vacuum packaging,
however the maximum content of myoglobin was found in the control samples (untreated) but in
oxymyoglobin and met myoglobin maximum content was found in treated samples. Our outcomes
have similarity with the findings of
[34]
who stated that under aerobic packaging and 0 day of storage
period the myoglobin content was higher but when the samples treated with different dose of radiation
lower content was found in samples treated with high dose (4.5kGy). Oxymyoglobin and met
myoglobin found to have higher content in aerobically packaged samples when treated with
(4.5kGy) on the 40
th
day of storage period. On the other hand, control samples (0kGy) non-
irradiated found to have lower content of oxymyoglobin and met myoglobin on 0 day of storage
period. Our findings are in agreement with
[31]
who stated that chicken meat samples treated with (2
kGy) found to have lower content of myoglobin in aerobically packaged samples at 14 days of storage
interval, whereas, the samples that were treated with 2 kGy gamma radiation vacuum packaged have
lower levels of oxymyoglobin and metmyoglobin on the 14th day of storage period.
Sensory evaluation PSE enriched beef patties
The sensory attributes of a food product are very important in consumer demand. The
sensory evaluation of PSE enriched beef patties was carried by trained panelists. The sensory
scores of PSE enriched beef patties are shown in the Table 10. The statistical result of sensory
score for appearance, taste, texture, odor, and overall acceptability of irradiated PSE beef
patties is shown in Table 10. Sensory attributes indicated a significant variation with respect to
the dose of gamma irradiation but changed significantly with storage period. The maximum
score for appearance (7.8 ± 0.29), taste (7.6 ± 0.28), texture (7.9 ± 0.30), odor (7.6 ± 0.27) and
overall acceptability (7.96 ± 0.28) was analyzed in the control (0KGy) on the 0 day of storage
period whereas, the minimum score for appearance (6.02 ± 0.07), taste (7.6 ± 0.28), texture
(5.9 ± 0.8), odor (5.2 ± 0.03) and overall acceptability (5.03 ± 0.6) was analyzed on the 14 day

of storage period. With the increase in storage period score for various sensory features
significantly decreased. During storage there was decrease in the sensory score because of
higher level of lipid oxidation initiated by the irradiation, which results in less acceptability,
but the overall acceptability was in the range of acceptance. Our findings is similarity with the
results of Lewis et al.
[50]
who depicted that the sensory score in chicken meat decreased with
irradiation during the storage duration of 28 days. Moreover, our results are in agreement
with
[31]
who reported that with the increase in storage duration there was significant decrease
in all the sensory score of gamma irradiated chicken meat. Another study is in agreement with
our finding in which ostrich and chicken meat were treated with kale leaf powder and gamma
irradiation. The slight changes in sensory parameters of both types of meat were observed
during storage on different treatments.

Conclusion and limitations
It is concluded that different doses of gamma irradiation significantly improved the quality of beef
patties with some insignificant changes in physicochemical properties during storage period. The
preservative and antioxidant potential of (PSE) poppy seed extract patties during storage were revealed
by physical, physicochemical and microbial analysis. The results showed that the samples treated with
5kGy+PSE were in well condition after the storage interval. There was decline in the antioxidant
profile during storage, but it was higher in vacuum packaged samples as compared to aerobic packaged
samples. Moreover, the TBVN value was lower in vacuum packaged samples as compared to aerobic
packaged samples during the storage period. The influence of PSE was positive on the storage of beef
patties as well as their antioxidant profile was good as compared to controls. The gamma irradiation
and phenolic nature of PSE efficiently enhanced the physical and chemical profile of beef patties. The
irradiation technology keeps the ability to eliminate the microorganism from meat and meat products
but high dose of irradiation cannot suitable because during irradiation processing the oxidation
process start. Poppy seeds contain different type of antioxidants that can help to improve the stability
of meat products but it also sources of morphine and codeine. High concentration of poppy seeds
extract may be harmful for human health.

Peanuts produce millions of tons of high‐protein peanut meal (after oil extraction) annually that can be used for food. Peanut protein, as a plant‐based protein, is a great alternative to animal protein to address protein deficiencies and rising health problems in the world. It has a high nutritional value, while the globular structure results in poor functional properties, limiting its application. Better functional properties can be obtained through processing and modification. This paper elaborates the nutritional and functional properties of peanut protein and highlights the application of peanut protein in food industry in recent years. Applications for peanut protein include meat and milk substitutes, edible films, nanoparticles, and some new technologies such as electrostatic spinning and three‐dimensional (3D) printing in recent years. This paper could improve people's understanding of the molecular structure of peanut protein and the physicochemical properties associated with the structure changes during processing. It could also contribute to better utilisation of peanut protein, providing more varieties of peanut protein products for the food industry.

The current investigation was conducted to evaluate the result of gamma irradiation doses and kale leaf powder (KLP) on microbiological assay (total aerobic bacteria and coliforms), quality parameters (Hunter’s color [L*, a* and b*] and heme pigment [Mb and MetMb]) and stability modifiers (total volatile basic nitrogen [TVBN], thiobarbituric acid reactive substances [TBARSs], and peroxide value [POV]) of ostrich and chicken meat under different storage intervals (0, 7 and 14d). Gamma irradiation dose (3kGy) with or without kale leaf powder (1% and 2%) was applied. The TPC and coliform outcome indicated that irradiation and storage caused significant changes in both meat patties while the microbial load was recorded zero at the treatment 3kGy. TVBN, TBARS and POV changed significantly in ostrich and chicken meat with different treatments and storage periods. TVBN value was observed high in ostrich meat at the treatment (3KGy) on the end of storage, whereas the higher values of POV and TBARS were evaluated in the chicken meat sample at 3kgy on 14th day of storage. The myoglobin, met-myoglobin, L*, a*, and b* showed significant changes with respect to different treatments and storage periods. The higher Mb value was seen at 2% KLP at day 0 of storage in ostrich meat and the extreme MetMb value was found at 3kGy at the end of storage. The L* and b* were observed high in chicken meat, whereas in ostrich meat, a* value was found high. In both types of meat, slight changes were observed in appearance, taste, texture, flavor and overall acceptability. However, it is concluded that both types of meat treated with 3kGy + KLP were examined better for quality, safety and stability during storage.

This study investigated the effect of different doses (0, 3, and 7 kGy) of e‐beam on the microbiological and physicochemical qualities and the profile of fatty acids of the frozen duck meat (FDM). Electron beam at the dose of 3 kGy showed more than 2 log and 1 log cycles of reduction in the total bacterial (TAB) and coliform counts (TCC), respectively. The results indicated an increase in the TBARS values (1.50 ± 0.02 mg MDA/kg), peroxide value (0.83 ± 0.04 meq peroxide/kg), and total volatile base nitrogen (1.31 ± 0.16 mg/100 ml), but no effect on the sensory parameters. Irradiation lowered the lightness (L*) (31.87 ± 0.98) and redness (a*) (11.04 ± 0.20) values but elevated the metmyoglobin content in FDM. In addition, irradiation had no effect on the benzopyrene content; however, a reduction was observed in the vitamin A (0.239 ± 0.015 µg/g) and vitamin E (1.847 ± 0.075 µg/g) contents of the FDM samples. There were no trans‐fatty acids present in the treated (irradiated) as well as the untreated (nonirradiated) meat samples (FDM), whereas the fatty acid content decreased in irradiated samples, in contrast with the nonirradiated control. Electronic nose clearly discriminated between the nonirradiated and irradiated FDM based on principal component analysis. It is concluded that the e‐beam successfully improved the microbial quality of FDM with slight changes in physicochemical properties, but without altering its sensory properties. This study investigated the effect of several doses (0–7 kGy) of e‐beam on the microbiological and physicochemical qualities and fatty acid profile of frozen duck meat (FDM). E‐beam at 3 kGy showed more than 2 log and 1 log cycles of reduction in the total bacterial and coliform counts, respectively. The results indicated an increase in the levels of thiobarbituric acid reactive substances, peroxide value, and total volatile base nitrogen, but no effect on the sensory parameters.

The experiment was conducted on fresh broiler meat treated with 60Co gamma irradiation having dose of 0 (T0), 1 (T1), 2 (T2) and 3.5 kGy (T3)) and stored 0, 30 and 60 days at -20ºC to estimate the effect on proximate, sensory, physicochemical, biochemical and microbial changes in broiler meat. Factorial experiment (4x3) in completely randomized design (CRD) replicated three times per cell was applied to study the variation among treatment combination. Color was changed significantly (p<0.05) with higher irradiation doses. DM, EE, CP was increased, and Ash and pH was decreased significantly (p<0.05) with higher irradiation doses. Thiobarbituric acid reactive substances (TBARS), Peroxide value (PV), Free fatty acid (FFA), cooking loss was increased significantly (p<0.05) with irradiation level and storage period. Total viable count (TVC), Total coliform count (TCC), Total yeast and mold count (TYMC) was significantly (p<0.05) reduced with irradiation level. Considering all traits it can be concluded that irradiation significantly decreased microbial population and maintain nutritional quality of broiler meat. The irradiation dose 2.0 kGy showed most acceptable for microbial population reduction, maintains overall acceptability and for shelf life extension of broiler meat comparison to non-irradiated meat sample.

This study was carried out to evaluate the impact of gamma irradiation and turmeric powder (TP) on microbial quality (total aerobic bacteria and coliforms), physicochemical quality (pH, Hunter’s parameter, oxidative and microbial stabilities, haem pigment), stability, and antioxidant status of chicken meat. Accordingly, two doses (1 kGy and 2 kGy) of gamma irradiation alone and in combination with 3% TP along with the control (0 kGy) were applied. Aerobic and vacuum packaging were used for storage of chicken meat on the 0, 7th, and 14th days of storage at refrigeration temperature (4°C). The microbiological results showed that the contamination level decreased as the dose of gamma irradiation was increased for both total bacteria and coliforms, whereas no contamination was documented in the group treated with 2 kGy+TP for both aerobic and vacuum packaging. The results further showed that pH, haem pigment, and Hunter’s colour were also significantly influenced with respect to different groups. The peroxide value (POV), thio-barbituric acid reactive substances (TBARS), and total volatile basic nitrogen (TVBN) differed significantly in chicken meat with different treatments and storage intervals. Higher POV and TBARS were noticed in chicken meat treated with 2 kGy under aerobic packaging after 14 days of storage, and TVBN was higher in the control on the 14th day under aerobic packaging. Total phenolics and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity were also higher in chicken meat treated with 2 kGy + TP on 0 day of storage. Furthermore, higher sensory attribute scores for attributes like appearance, taste, texture, flavour, and overall acceptability were found in the 2 kGy-treated group. It is concluded that chicken meat treated with 2 kGy+TP was considered better for microbial and physicochemical quality, antioxidant activity as well as sensorial properties of chicken meat.

Poppy seeds are obtained from the opium poppy (Papaver somniferum L.). They are used as food and to produce edible oil. The opium poppy plant contains narcotic alkaloids such as morphine and codeine. Poppy seeds do not contain the opium alkaloids, but can become contaminated with alkaloids as a result of pest damage and during harvesting. The European Commission asked EFSA to provide an update of the Scientific Opinion on opium alkaloids in poppy seeds. The assessment is based on data on morphine, codeine, thebaine, oripavine, noscapine and papaverine in poppy seed samples. The CONTAM Panel confirms the acute reference dose (ARfD) of 10 μg morphine/kg body weight (bw) and concluded that the concentration of codeine in the poppy seed samples should be taken into account by converting codeine to morphine equivalents, using a factor of 0.2. The ARfD is therefore a group ARfD for morphine and codeine, expressed in morphine equivalents. Mean and high levels of dietary exposure to morphine equivalents from poppy seeds considered to have high levels of opium alkaloids (i.e. poppy seeds from varieties primarily grown for pharmaceutical use) exceed the ARfD in most age groups. For poppy seeds considered to have relatively low concentrations of opium alkaloids (i.e. primarily varieties for food use), some exceedance of the ARfD is also seen at high levels of dietary exposure in most surveys. For noscapine and papaverine, the available data do not allow making a hazard characterisation. However, comparison of the dietary exposure to the recommended therapeutical doses does not suggest a health concern for these alkaloids. For thebaine and oripavine, no risk characterisation was done due to insufficient data. However, for thebaine, limited evidence indicates a higher acute lethality than for morphine and the estimated exposure could present a health risk.

This study analysed the impact of method of poppy seed lipid extraction (cold pressing, Soxhlet extraction with n-hexane, supercritical fluid extraction (SFE) with pure CO2 and CO2 with 10% of acetone, ethanol, or ethyl acetate as co-solvents) on the oil yield, recovery of total oil and the composition and quality indices of the obtained oils. According to the method of extraction used, the recovery of oil varied from 63.6% to 93.4%, while the fatty acid composition was constant, with a predominance of linoleic and oleic acids (ca 71% and 16% of total fatty acids, respectively). Phytosterol contents varied from 2521 mg/kg to 2933 mg/kg, with the highest variation of cycloartenol content. Tocopherols were determined at the level of 122–133 mg/kg, with only two homologues identified (α- and γ-tocopherols). It was found that γ-homologue constituted at least 93% of the total fraction. Squalene was determined in the amount of 21.3–35.0 mg/kg. Oils extracted by the use of SFE also contained small amounts of phenolic acids (up to 2.58 mg/kg). Among the tested quality indices, acid value and induction time were mostly affected by the method of extraction.

This study was carried out to investigate the effects of irradiation doses (0, 1.5, and 3 kGy) on the physicochemical and microbial qualities of meat balls with or without moringa leaf powder (MLP) and 14 days under refrigerated storage. The results indicated that irradiation and storage caused significant changes on physicochemical attributes of meatballs and the decreasing trend in stability was observed in meatballs stored under aerobic packaging. Highest pH and TVBN were observed in samples treated with 3 kGy at day 14 in aerobic packaging without MLP. The addition of MLP and higher doses of irradiation reduced the total aerobic bacteria and coliforms counts. Different treatments did not affect the sensory quality of chicken samples. Hence, it was concluded that irradiation dose at 1.5 kGy with the addition of MLP and vacuum packaging may enhanced the safety, quality as well as stability of chicken meat during storage intervals. The health benefits of meat and its products make them popular among the consumers. Hence, this study indicates the significance of irradiation (at low dose) in preserving the meat for long time without causing immense deteriorative changes in its quality. Moreover, the addition of moringa leaf powder (MLP) (a natural antioxidant) and type of packaging (vacuum packaging) plays a vital role in maintaining the shelf life and stabilizing the safety of meat without causing major changes in its physicochemical, functional, and sensory characteristics.

The present study was carried out to develop low fat buffalo meat cookies incorporated with Poppy seeds (Papaver somniferum) powder (PSP) as fat replacer. Meat cookies were incorporated with 0.5%, 1.0% and 1.5% seed powder to replace 20%, 30% and 40% hydrogenated vegetable fat. The formulation was maintained with addition of water. There was significant difference (P<0.05) between control and treatments for physico-chemical properties except pH, thickness and diameter of cookies. The cooking yield of cookies was comparable upto 1% level, but decreased significantly (P<0.05) at 1.5% PSP incorporation. There was a significant increase (P<0.05) in moisture, protein and ash percentage but fat percentage decreased significantly (P<0.05) with PSP incorporation in cookies. Mean spread ratio decreased significantly (P<0.05) at higher level. There was significant decrease (P<0.05) in all sensory attributes of cookies with PSP incorporation except crispiness. Carabeef cookies with 0.5% ground poppy seeds powder replacing 20% fat had highest overall acceptability scores among all treatments. There was no significant difference in hardness and adhesiveness among control and treatments, but shear force value was significantly higher (P<0.05) at 1.5% level. There was no significant difference for redness, yellowness, chroma and hue angle values. Therefore, on the basis of various physico-chemical properties and sensory evaluation, incorporation of 0.5% poppy seeds powder was selected as optimum to replace 20% of hydrogenated vegetable fat in carabeef cookies without compromising quality attributes.

As a promising non-thermal decontamination technique, γ-irradiation has been practically used to ensure microbial safety of meat and meat products, but its effects on the properties of meat have not yet been fully understood. So, this study mainly investigated the effects of different doses irradiation (0, 3, 5 and 7 kGy) on the muscle protein conformation, surface hydrophobicity, solubility, particle size, turbidity and thermal stability. The results of CD spectroscopy showed that 3 kGy disrupted the beta-sheet to form unordered structures in SP while increasing dose level recovered the ordered structures in SP, especially the increased alpha-helix content of SP after 7 kGy irradiation. In case of MP, beta-turn exhibited a dose-dependent reduction and 7 kGy irradiation resulted in a dramatic increase in beta-sheet compared with MP control (P < 0.05). The DSC and SDS-PAGE results indicated that 3 kGy irradiation could promote the actomyosin formation in MP, but ≥5 kGy irradiation favored its depolymerization. And after irradiation, the solubility and particle size of SP was reduced significantly (P < 0.05). Consequently, turbidity of SP and MP reached their maximum value at 5 kGy and 3 kGy irradiation, respectively. Upon irradiation, WHC of both SP and MP gels dropped significantly (P < 0.05) with increasing dose level. Rheological analysis demonstrated that, during thermal gelation, the G′ and G″ of SP decreased as irradiation dose increased due to greater protein denaturation. Microrheological behavior and Turbiscan results showed that irradiated SP samples exhibited significantly higher TSI compared with SP control, but ≥5 kGy irradiation exhibited a stronger EI and MVI value in MP, indicating the enhanced inter-droplet resistance force inside MP.

Oxidative damage is one of the main reasons for loss of quality in sheep and goat meat and meat products. Synthetic antioxidants are the current solution to stabilize oxidative process and extend the shelf life of such products; however, the negative impact on health may impose a risk to consumers. Natural antioxidants, extracted from several vegetable sources, have been considered an attractive alternative for this conflicting situation. Phenolic compounds are minor components in herbs, spices, tea and fruits that display potential application against the progression of lipid and protein oxidation and their consequences for meat quality, which can even overcome the protective effect of synthetic compounds. This review aims to discuss the mechanisms associated to lipid and protein oxidation and their implications on meat quality attributes and provides recent data regarding the application of natural antioxidants in sheep and goat meat products, which have a high susceptibility to oxidative processes compared to other red meats.
