Abstract
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.
