Shelf-life prediction of pineapple dodol packed with edible film using accelerated shelf life tests

Abstract

The accelerated shelf-life tests (ASLT) can be applied to predict the shelf life of products to reduce time and cost. 'Dodol', semi-wet food, is easily damaged by microbial activity. This study aims to predict the shelf life of pineapple dodol packed by an edible film with and without the addition of antioxidant and antimicrobial. ASLT with the Arrhenius model was used to estimate the shelf life of the dodol products. The dodols with different packaging were stored at some temperatures of 20, 30 and 40°C for 42 days, analyzed periodically to determine total plate count, moisture content, and free fatty acid. The results showed that the shelf life of dodol packed with polypropylene plastic was the longest. In addition, dodol wrapped with edible film with antimicrobial-antioxidant had a longer shelf life than that of without antimicrobial-antioxidant. Based on the total plate count, the shelf life of dodol wrapped with polypropylene plastic, the edible film with antimicrobial-antioxidant, and the edible film without antimicrobial-antioxidant were 32, 26, and 22 days, respectively.
