The decay percentage of coated fruits stored at 21±1◦C and 75-80% Relative humidity was reduced significantly compared to uncoated sapota. Developments of black spots and shriveling were observed in coating treatments T0 and T1 after 14 days of storage. At the end of storage, the decay percentage of the coated sapota was less than 15 %
in T1 and T2 while that of uncoated ones was 50 %. Ghaouth et al. [16] reported that chitosan induces chitinase, anenzyme which catalyzes the hydrolysis of chitin, which is a component found in the cell walls of fungi that prevents the growth of fungi on the fruit and vegetables [30-31]. In this study, it was found that the decay control of T3 was better than that of T1 and T2 and showed efficacy against decay incidence of sapota fruit.
