This study introduces a sustainable approach to simultaneously produce pectin and phenolic compounds from pistachio industrial waste and applies them in the formulation of low-phenylalanine cookies. The co-optimization process was performed using the microwave-assisted technique and a Box-Behnken design, considering four variables and two responses...

The pectin from different sources varies in view of major domains (homogalacturonan HG, rhamnogalacturonan, RG-I or RG-II) and extent of esterification determining major functional properties such as gelling, viscosifying, or stabilizing. The mechanism of sustainable extraction methods (ultrasound, US; microwave, MW; pulsed electric field, PEF; ult...

BACKGROUND The rind from cantaloupe is an agricultural waste of cantaloupe industrial processing. The current study tried to (i) evaluate the potential use of cantaloupe rind as a pectin source, (ii) optimize the factors of microwave‐assisted extraction process using Box–Behnken design, and (iii) characterize the isolated pectin using various physi...

Background: Eggplant (also known as aubergine) by-products, which consist mostly of peel and calyx, are generated in substantial amounts by industrial food processing sections and usually discarded as waste without further utilization. However, studies have demonstrated that these by-products are superb sources of bioactive compounds. Therefore, th...

In this study, unrippen grape pomace as a valuable source for pectin extraction was investigated using acidic extraction method. For this purpose, Box-Behnken design with four independent variables in three levels (Time (30-90 min), Temperature (70-90℃), pH (1.5-3.0) and liquid to solid ratio (20-40 v/w)) was used to optimize the pectin extraction...

Abstract Microwave-assisted extraction of pectin from walnut green husk (WGH) was optimized using Box-Behnken design. The effects of microwave power, pH, irradiation time, and liquid/solid ratio on the extraction yield were investigated. The characteristics of WGH-pectin extracted at the optimal condition were evaluated through physicochemical, str...

In this study, microwave-assisted extraction of pectin from Cucumis melo peel as food waste was optimized. For this purpose, Box-Behnken design with three independent variables of microwave power, irradiation time and pH at three levels was used to achieve the maximum extraction yield. The results showed that the maximum extraction yield (19.4 ± 0....

In this study, Box–Behnken design was applied to optimize the ultrasound-assisted extraction (UAE) and heating extraction (HE) conditions for pectin production from pistachio green hull (PGH). The pectin extraction yield at optimal condition for UAE (ultrasound power of 150 W, pH of 1.5 and time of 24 min) and HE (temperature of 70 °C, time of 90 m...

The microwave-assisted extraction of pectin from sweet lemon peel (SLP) was optimized using Box-Behnken design. The highest pectin yield (25.31%) was observed under optimal condition (microwave power of 700 W, irradiation time of 3 min and pH of 1.5). The physicochemical, structural and some bioactivity of the SLP pectin isolated at optimum conditi...

The ultrasound-assisted extraction of pectin from walnut processing waste was optimized by Box-Behnken design. The highest extraction yield (12.78±0.83%) was obtained at ultrasound power of 200 W, sonication time of 10 min, pH of 1.5 and LS ratio of 15 v/w. The resulting pectin in these conditions was rich in galacturonic acid (69.44%) and was high...

Based on a bio-refinery concept, the valorization of eggplant peel wastes (EPW) in the production of multiple value-added products was aimed. The acid-free extraction process was applied in the simultaneous recovery of pectin and phenolic compounds. The extraction variables were optimized by response surface methodology using a Box-Behnken design a...

Eggplant peel as a new source was used for pectin extraction using ultrasonic method. The extraction process factors were optimized using Box-Behnken design (BBD) and under optimal conditions (ultrasound power of 50 W, irradiation time of 30 min and pH of 1.5), the predicted extraction yield (35.36 g/100 g) was validated by the experimental results...

In the present study, the various properties of pectin extracted using microwave-assisted extraction (MAE) from eggplant peel and eggplant calyx (as food processing wastes of eggplant) were compared with each other. The eggplant peel pectin (EPP) exhibited higher extraction yield (29.17%) than eggplant calyx pectin (ECP; 18.36%). Both of EPP and EC...

In this work, a Box-Behnken design (BBD) with three variables (ultrasound power, irradiation time and pH) in three levels was applied for pectin extraction optimization. The optimization process showed that the maximum extraction yield was 28.07 ± 0.67% in ultrasound power of 150 W, irradiation time of 10 min and pH of 1.5 (as optimum conditions)....
