Application Of Chitosan-Based Apple Peel Polyphenols Edible Coating On The Preservation Of Strawberry (Fragaria Ananassa Cv Hongyan) Fruit

This study was determined to investigate the efficacy of chitosan (CS)-based apple peel polyphenols (APP) composite coatings to enhance the storage quality of strawberries. Strawberries were coated with CS-APP1 (0.25% APP), CS-APP2 (0.50%), CS-APP3 (0.75%), CS-APP4 (1.0%), and stored at 20 degrees C and 35-40% RH. The uncoated fruit was considered as control. The fruits were evaluated for weight loss, decay, firmness, bioactive compounds, titratable acidity, and total soluble solids (TSS). The results revealed that CS-APP coatings had a significant effect on all the tested parameters. The weight loss and decay percentage were reduced to 10.91% and 19%, respectively, in the CS-APP4 treatment group. The highest value of TSS (6.8%) was observed in the CS-APP3 treatment group on the 6th day of storage. Coatings with CS-APP4 exhibited the maximum acid content (0.78 g/100 g) as compared to the CS only (0.68 g/100 g). The total phenol content was highest (1.3 mg/g) in the CS-APP2 treatment group at the end of storage. CS-APP2 composite coating could be effectively utilized to extend the postharvest life of strawberries as it retarded the senescence and maintained quality attributes of the fruits during storage.
