Summary
The research was conducted on ber fruit (Ziziphusmauritiana), in which an edible coating of aloe vera gel/tamarind starch/whey protein concentrate was prepared, applied on ber fruit by dipping method, and packed in polyethylene terephthalate (PET), polypropylene (PP) and polyethylene (PE) to evaluate the effectiveness of the edible coating on the postharvest quality and shelf life. A comparative study between uncoated and coated samples at two different temperatures, i.e., 4 ± 1 °C and 25 ± 2 °C was done. Bers' physiochemical analysis and sensory quality were evaluated for 31 days. The weight loss, pH, TSS, titratable acidity, total sugar, total protein and total phenol in coated ber kept in PP were 37.48%, 5.50, 14.4°Brix, 0.14%, 11.99%, 0.55% and 0.17% by the 27th day of storage at 4 ± 1 °C which turned out to be the best storage condition by showing a delay in the physiochemical changes. Edible coating delayed the loss of firmness and the change in the L*, a* and b* values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
