Abstract
The accelerated shelf-life tests (ASLT) can be developed to predict shelf-life of products to reduce time and cost. ^Dodol^, semi-wet food, is easily damaged by microbial activity. In this study, the pineapple dodol was wrapped with edible film with and without antimicrobial-antioxidant and polypropylene plastic. 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 oC for 42 days, analyzed periodically to determine total plate count, moisture content, and free fatty acid. The results showed that 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 total plate count, the shelf life of dodol wrapped with polypropylene plastic, an edible film with antimicrobial-antioxidant, and edible film without antimicrobial-antioxidant were 32, 26, and 22 days, respectively
