Application of biopolymer film for edible coating on fruits and vegetables to increase their shelf life.

Sunita Mishra, Jagriti Joshi

In this study, kiwifruit and apple coated with biopolymer film by dipping method were stored at Room Temperature (RT for 15 days and investigated. The effectiveness of biopolymer coating on all treatment was studied by using physiochemical characteristics such as pH, TSS microbiological testing, morphological changes within the samples by SEM and EDX to find the different elements of composition present in biopolymer coating and in 15 days of storage period. The result indicates minimal changes in physicochemical parameters during the storage period, such as TSS, pH and microbial count of coated samples as compared to uncoated samples. Coating apple and kiwifruit with starch-based biopolymers reduces water loss and prevents microbial growth. The application of biopolymer coating on kiwifruit and apples is useful for increasing the stability of perishable fruits such as kiwifruit and apples.
