An experiment was conducted to evaluate the conservation of blackberry, cv. Tupy, stored under refrigeration and coated with different edible coatings. Four treatments were carried out: control T1 (uncoated), T2 (chitosan 1.5 %), T3 (cassava starch 2.5 %) and T4 (kefir grains in water 20 %), stored at temperatures of 0 and 10 °C; 1.0 % (m/v) sorbitol/glycerol was added as plasticizers. Chemical and physical-chemical evaluations (weight loss, firmness, pH, titratable acidity, soluble solids, SS/TA ratio and anthocyanins) were made, besides rot incidence. The results showed that cooling to 0 °C combined with T2 showed an effect in reducing the physiological loss of weight (4.41 %), in retaining fruit firmness (19.1 N) and presenting lower incidence of rot (6.19 %). Likewise, in physical and chemical parameters: SS did not alter significantly during the whole period of 18 days of storage.

Ash gourd (Benincasa hispida) is cultivated for its medicinal benefits, with processing enhancing its health properties and shelf life. The processing industries generate significant byproducts, with peel and seeds common across all methods, along with lime (from petha sweet production), brine wastewater (from fermented foods), and pulp from juice processing. This review focuses on peel, seeds, and lime wastewater, which contain valuable compounds like polyphenols, terpenoids, essential oils, and ribosome-inactivating proteins known for their antioxidant and antibacterial properties.

Background: The edible seeds of Ocimum gratissimum and Ocimum basilicum were found to be a potent source of phytochemicals with noteworthy antioxidant, antidiabetic, and antimicrobial properties. This study aimed to investigate the impact of germination and extraction solvents (ethanol (EtOH), distilled water) on the therapeutic properties exhibited and the ability of seed extracts to act as natural food preservatives.
Results: The EtOH extracts of germinated O.

Edible films are significant in prolonging the shelf life of meat products. Herein, we prepared some edible coatings (EW/TNPCSs) based on egg white/chitosan/pectin as polymer matrix, containing tannic acid-nisin composite nano-crosslinker with antibacterial-antioxidant activities. The results of preservation indicated that the prepared EW/TNPCSs reduced the water loss of chilled pork and delayed the changes of taste, texture and surface color.

Starch-based foods are the most common foods in the daily diets. However, starch-based foods are prone to starch retrogradation, resulting in texture hardening, taste deterioration and nutrient loss. This paper reviewed the mechanisms and the influencing factors of starch retrogradation in starch-based foods, and the strategies to mitigate it.

This study aimed to fabricate edible films from tapioca (T) and potato (P) starch, assessing their physicochemical properties and biodegradation across different ratios (T100P0, T70P30, T50P50, and T30P70). The films underwent evaluation for moisture content, thickness, water vapor permeability, and color values. T100P0 and T30P70 formulations exhibited the highest film transparency at 43.
