Applying the method of nuclear and issue spectrometry there were determined the qualitative structure and the quantitative content of elements in raw materials (leaves, stalks, flowers) of a summer squash (Cucurbita pepo L.), collected in different stages of vegetation. As concerning quality it was established that leaves, stalks, flowers had ident...

... has been found that all types of the raw materialleaves, stalks and flowers concerning the qualitative aspect have the identical elemental composition presented by 19 elements. For macroelements the regularity of increase in the content at the stages of vegetation was observed (see Fig. 1). There is the following regulari- ty of the elemental content for the raw material: leaves and flowers -K > Ca > Si> Mg > P > Na, stalks -K > Ca > Mg > Si > P > Na. The content of such elements as molybdenum, cobalt and lead is lower than 0.03 mg/kg, arsenic, cadmium and mercury is lower than 0.01 mg/kg. The highest content in 3 types ...

... has been found that all types of the raw material - leaves, stalks and flowers concerning the qualitative as- pect have the identical elemental composition present- ed by 19 elements. For macroelements the regularity of increase in the content at the stages of vegetation was observed (see Fig. 1). There is the following regulari- ty of the elemental content for the raw material: leaves and flowers -K > Ca > Si> Mg > P > Na, stalks -K > Ca > Mg > Si > P > Na. The content of such elements as molybdenum, cobalt and lead is lower than 0.03 mg/kg, arsenic, cadmium and mercury is lower than 0.01 mg/kg. The highest content in 3 types of the raw material is de- termined for potassium. The content of this element in stalk is 3340-5050 mg/kg, and it is higher compared to leaves by 1.2-1.5 times (2850-3354 mg/kg), compared to flowers -by 1.1-1.3 times (3000-4000 mg/kg). In leaves, stalks and flowers the considerable content of calcium (1350-1700 mg/kg, 1000-1576 mg/kg, 1007-1345 mg/kg, respectively), silicоn (1299-1400 mg/kg, 470-500 mg/kg, 1000-1130 mg/kg, respectively) and magnesium (8000- 1086 mg/kg, 759-800 mg/kg, 897-905 mg/kg, respec- tively) has been ...

... Their health benefits are due to their vitamin, mineral, and antioxidant content [1][2][3][4][5][6][7]. Among edible flowers, a prominent role is played by the flowers of the zucchini plant (Cucurbita pepo L.), characterized by a bright yellow color and a delicate flavor, as well as by medicinal and functional properties [8][9][10][11][12]. Zucchini flowers are an important source of phytochemicals, essential amino acids, folic acid, and antioxidant compounds such as carotenoids, polyphenols, and ascorbic acid [13][14][15][16]. ...
To maintain the shelf life of fresh-cut zucchini flowers, low temperatures and wrapping with plastic film have been used. In this study, storage at 5 °C for 8 days has been studied, using polyester (an oxygen permeability reduction of 63%) and low-density polyethylene (LDPE) with an oxygen permeability reduction of 24%. In addition, the novelty was investigating the possibility of introducing washing into the process, a rather difficult operation given the high sensitivity of this product to handling. The washing of flowers could ease the consumption of fresh-cut zucchini flowers as they are ready-to-use. The following measurements were carried out: respiration rate, color, firmness, pH, and sensory analysis. The findings showed the polyester film allows the best conservation, representing a barrier to gas diffusion and maintaining an atmosphere rich in CO2 and poor in O2. The flowers kept a better texture than those wrapped in LDPE. Using polyester film packaging, sensorial and structural characteristics were maintained for a longer period, and the aspect of the ready-to-use fresh-cut zucchini flowers was satisfying until day 5.
... Fiber also helps maintain healthy blood sugar levels and provides energy throughout the day. The presence of high ash content indicates that squash has greater mineral element content, which improves the metabolic process and growth (Elinge et al., 2012;Fedchenkova et al., 2015;Nwofia et al., 2012). We observed similar qualitative properties due to pruning and vermicompost application. ...
The present research was undertaken with the aim of justifying the effect of morphological, physiological, and nutritional properties in organically produced zucchini squash. The experiment consisted of two factors: three levels of pruning (P 0 = no pruning, P 1 = primary pruning at 20 days after transplanting (DAT), and P 2 = secondary pruning at 30 DAT) and four levels of vermicompost application (V 0 = control, V 1 = 5 t/ha, V 2 = 10 t/ha, and V 3 = 15 t/ha). The results demonstrated that morphological parameters, reproductive components, and yield and proximate compositions were significant differences among the treatments. Increased male and female flower production were recorded from primary pruning with 10 t/ha vermicompost treatment plots compared with control treatments. Finally, increased fruit number, individual fruit weight, fruit length, fruit diameter, total yield, carbohydrate, protein, crude fat, fiber, and ash were reported from the same treatment combination (P 1 V 2 ). Taken together, 10 t/ha vermicompost with primary pruning appear to provide maximum output in terms of yield and nutrient value compared with other treatments.
... From these results, the seeds have a high content of the ash therefore the ash content of the seeds is expected to have a high concentration of various mineral elements which are expected to speed up metabolic process, improve growth. [25,26,29,30,31] Due to the high content of the moisture of fruits and fruit pulp of Squash (Cucurbita pepo), as shown in Table (1) (70.25, 75.59 and 5.63%) respectively, therefore the rapid spoilage of fruits or fruit pulp of Squash (Cucurbita pepo) can observe. So we need to store the fruit of Squash in cool condition if they are to be kept for a long period without spoilage. ...
... And also, the Na/K ratio in the body is of great importance for the prevention of high blood pressure. [29,30,31] This study revealed that the fruits, seeds and fruit pulps of Squash (Cucurbita pepo) have high contents of K and Na Therefore, the Squash fruits are very important in the human diet for prevention of high blood pressure. [31] Iron performs several functions in the body, it helps in the formation of blood and it helps in the transfer of oxygen and carbon dioxide from one tissue to another.Iron deficiency results in an anaemia which impairs muscles metabolism, its deficiency in children result in an impaired learning ability and behavioural problems. ...

The nutritional potential of fruits, fruit pulp and seeds of Squash (Cucurbita pepo L.) collected from Giza, Egypt was evaluated for their proximate values and mineral composition. In addition to; the total phenolic and flavonoid contents and antioxidant activities by using (DPPH, ABTS and TAC) of the defatted methanolic extract of fruits, and seeds of (C. pepo) were determined. The results indicated that the fruit pulp and fruits have a high content of moisture and crude fibres whereas, the seeds have high protein, fat and ash contents. The fresh fruit pulp and fruits had a high content of β- carotene. Although fruits and fruit pulp contained high amounts of magnesium, potassium, sodium, phosphorus, manganese and calcium but the seeds have highest values. Parallel to the results revealed the seeds have a high content of phenolic and flavonoid and also higher antioxidant activity. The results also showed a clear relationship between total phenolic and flavonoid contents with the antioxidant activity of the seeds and fruits. From the obtained results, the fruits of (C. pepo) are good alternative source of nutritional content and essential minerals which required to human for a healthy and active life.
