Effects of Storage Conditions on Quality Change of Minimally Dried Jackfruit (Artocarpus heterophyllus Lam.) Bulbs

Quality of minimally processed jackfruit bulb was evaluated during storage at different storage times, temperatures, and types of packaging. The jackfruit pulps were first dried at 45 °C, stored in polypropylene plastics, zipper bags and plastic boxes. Quality parameters were evaluated every 5 days and based on phytochemical changes such as vitamin C, polyphenol, and antioxidant activity. Results revealed that polypropylene plastics were the best packaging product for retention of vitamin C content (5.837 mg/100g) antioxidant activity (7.458%) and phenolic compounds (2526.603mg/100g) after 30 days of storage. Figures for plastic boxes were 5.641 mg/100g, 5.249% and 2361.657 mg/100g, respectively. Similarly, zipper bags were 5.32 mg/100g, 5.895 % and 2173.867 mg/100g respectively. Sensory evaluation in terms of taste, color, texture, and overall acceptability showed that polypropylene packaging gave favorable scores and the products were highly accepted by trained evaluators.
