Chicken and eggs are considered the most common product in the world. Microorganisms on the surface and inside these food products reduce the shelf life and may be the causative agents of the disease among consumers. To solve this problem various methods of thermal and chemical treatment are used, which have several disadvantages. Radiation processing is a modern method of suppressing contamination of bacteria and increasing the shelf life of food products. Unfortunately, this technology has a negative effect on the physico-chemical and organoleptic properties of the product. Therefore, for food and hatching eggs the dose level is limited about 3 kGy. However to solve this problem it is possible to use a low-energy electron beam. This approach allows irradiating with a disinfecting dose only the surface and a shallow depth of products. Experiments on the irradiation of chicken meat and eggs were carried out at the accelerators URT-0.5 and URT-1. Studying the effect of irradiation with a nanosecond electron beam (NEB) on edible chicken eggs showed no significant changes in the eggs structure and physico-chemical properties. This is primarily due to the low depth of electron penetration. Therefore, most of the product is not irradiated by electrons. Thus, irradiation using the URT accelerators will reduce the main problem of the food radiation technology.

Abstract Objectives The study was conducted to prolong the shelf life of freshly harvested pomegranate fruits and to find out its physiochemical properties during storage. Materials and Methods Pomegranate fruits of variety ‘Bhagawa’ were stored in 200, 300 gauge high-density polyethylene (HDPE) package, and silicone membrane modified atmospheric storage system at ambient conditions and 10°C. Gas composition inside the package, texture, color, and overall quality parameters were evaluated at these two storage temperatures. The physico-chemical properties such as total soluble solids, titratable acidity, ascorbic acid content, total, reducing, and non-reducing sugars, and physiological loss in weight (PLW) were also determined. Results In ambient storage, the shelf life of pomegranate fruit was 10 days, whereas in modified atmosphere packaging (200 gauge HDPE, 300 gauge HDPE, and silicone membrane system), the shelf life of pomegranate fruits was extended up to 60, 60, 25 days at ambient and 96, 96, 65 days at 10°C temperature, respectively. Conclusions Among the 200, 300 gauge HDPE package, and silicone membrane system treatments T1, T5, and T8, respectively, were found better with respect to all the sensory and quality parameters studied.

This article presents the results of studies of the properties of marmalade with natural plant cryoadditives during storage for 3 months (90 days). To improve the organoleptic characteristics and antioxidant properties of marmalade, plant additives of cryogenic origin were used, namely cryopastes from quince, apple, carrot, pumpkin, grapes, and cryopowders from rose hips, sea buckthorn, and grapes. It is shown that the use of plant cryoadditives makes it possible to increase the biological value and antioxidant properties of new types of marmalade. For new types of marmalade with cryoadditives, during its shelf life, these properties have not been studied earlier. However, it should be noted that such studies are necessary and relevant for solving the problem of preserving the quality indicators and antioxidant capacity of marmalade with cryoadditives. New kinds of marmalade have high organoleptic characteristics during the whole storage period. It is shown that the storage conditions of marmalade, according to current regulatory documentation, are suitable for new marmalade products, since the physico-chemical and microbiological indicators vary, but remain within acceptable limits. Thus, the moisture content decreases to almost 31%, the acidity rises by 12–16%, compared to freshly prepared samples. The content of reducing substances increases by 30–64%. It is determined that the value of the antioxidant capacity of all the samples developed is much higher – almost 2.3–8 times than the same figure for the control sample. After the storage period, the antioxidant capacity is reduced by 15–35%, but this data also significantly exceeds the antioxidant capacity of the control sample. Storage of marmalade with cryopastes and cryopowders for 90 days is possible, since all the basic physico-chemical, microbiological, and organoleptic indicators at the end of shelf life meet the requirements. Indicators of antioxidant capacity for them also remain at a fairly high level. New technologies of jelly-fruit marmalade with plant cryoadditives have been introduced at 4 enterprises. 2 utility model patents have been received, and regulatory documents have been developed and approved for the manufacture of new jelly products.

In this experiment the effect on post-harvest preservation of papaya (Carica papaya L.) fruit coated with either Aloe gel (AG; 100%) or papaya leaf extract with Aloe gel (PLEAG; 1:1) was studied. To evaluate the role of coating on ripening behavior and quality of papaya the uncoated and coated fruits were stored and ripened at room temperature (25 °C-29 °C) and 82-84% relative humidity. Physico-chemical properties were analyzed at 4 day intervals during the storage period. The incidence of disease attack was also visually observed. The overall results showed the superiority of AG and PLEAG coating in lengthening the shelf-life of papaya fruit compared to controls which showed significant decay from 6th day onward and complete decay within 12 days of storage. The AG and PLEAG coated fruits maintained their shelf life for 12 days and decayed at 16th day. The coated fruits also maintained their color, flavor and firmness up to 12 days of storage. An increase in ascorbic acid content (120.2 mg/100 g) was also found in coated fruits in contrast to the control (59 mg/100 g). Only 27% disease incidence was observed in AG and 13% in PLEAG coated fruits as compared to control (100%) during the storage period. The results of this study show that both AG and PLEAG coatings have excellent potential to be used on fresh produce to maintain quality and extend shelf-life.

Vegetable beverage was part of a balanced diet that make sure the vigor and healthy body. Vegetable juices were rich in fiber content which was quickly inducing the feeling of satiety and also improve digestion. The objective of this study was to formulate and prepare ready to serve (RTS) banana pseudo stem beverage. Two banana varieties were selected viz., ottu vazhai (syn Mupaddai) (V1), vayal vazhai (V2). Banana pseudo stem beverage was developed from banana tender core, natural flavorings (lemon, mint)extracts, 2% citric acid as a anti-browning agent, KMS (70ppm) as preservative and CMC (0.1%) as a stabilizer. The proximate composition, physico- chemical analysis, sensory evaluation and microbial study of the pseudo stem beverage was evaluated using standard procedures. The beverages were evaluated at 15 days interval period. During storage conditions the quality of juice with minimum significant changes in chemical properties was observed with the addition of KMS. Based on the sensory evaluation, lemon juice flavored pseudo stem beverage was highly accepted by consumer than mint flavored beverage. Storage study for the pseudo stem beverage was also carried out and significant difference was noticed in beverage. Compare to vayal vazhai (V2), the yield of juice (87.0%) content was higher in ottu vazhai (syn Mupaddai) (V1).The maximum desirable results were obtained from (V1) lemon flavored beverage stored at refrigeration condition. The results were showed that pH (3.28 to 4.75), TSS (12 to 14.0° brix), Acidity (0.35 to 0.26) and vitamin C (0.77 to 0.59). From the storage studies, the lemon flavored pseudo stem beverage (Mupaddai variety V1) was found to be the best in nutrient retention and sensory evaluation than mint flavour beverage and it was accepted up to 45 days.
