Abstract

Coating of papaya fruit (Carica papaya L. cv Hongkong) with gum arabic (GA) has been found to enhance their shelf-life and postharvest quality. The objective of this study was to determine the effect of gum arabic on the antioxidant activity, physicochemical properties, sensory quality and microbial analysis of papaya fruits. Gum Arabic in aqueous solutions of 5% and 10% was applied as edible coating to green-mature papaya and stored at 13°C±1 for 15 days. The result of the study showed that papaya fruits coated with 10% GA and stored for 7 days had significantly (P<0.05) higher antioxidant capacity (TPC, TFC, FRAP, DPPH and ABTS) and sensory evaluation than the sample control or other treated fruits. In general GA affected significantly (P<0.05) the physicochemical properties (color, pH, TA, moisture and TSS) in papaya fruit at different concentrations with storage days the highest values were recorded in sample control (untreated) and the lowest values in GA10% and GA5%. In addition, the 10% concentration depicted a significant (P<0.05) decrease microbial records when stored with 10% GA. The results suggested that gum Arabic 10% preservative material, could delay the ripening process by inhibiting the respiration rate in the papaya fruit and improves the postharvest quality during cold storage.
