Abstract

In this experiment the effects of aloe vera gel coating on storage behavior of papaya at room temperature (290C-310C) was studied. Physico-chemical parameters such as color, physical changes, moisture, ash, acidity, vitamin C, protein, fat and total soluble solids (TSS) of papaya and aloe vera was determined at 3 days interval during the storage period. Among the physico-chemical parameters, color, physical changes, total weight loss and TSS contents increased significantly, whereas moisture content, vitamin C and titrable acidity decreased during storage. Control and 0.5% aloe vera treated papaya decayed from 6 days onward and completely decayed within 12 days of storage. On the other hand, 1% and 1.5% aloe vera gel coated papaya maintained their shelf-life for 9 and 12 days, respectively. Some of 1.5% aloe vera coated papaya decayed after 15 days. Papaya treated with 1.5% aloe vera solution, maintained their color & physical changes compared to other treatments up to 12 days of storage. The overall results showed the superiority of 1.5% aloe vera gel coating in extending the shelf-life of papaya upto 15 days compared to that of 0.5%, 1% aloe vera gel coating and control papaya. The present study describes the preparation and potential application of aloe vera gel coatings for enhancing the postharvest life and quality of papaya.
