Abstract
To determine the shelf life of a product, an appropriate method is needed. This research aims to predict the shelf life of instant chocolate by using accelerated shelf life test (ASLT) with the Arrhenius equation. Instant chocolate was stored at 30℃, 40℃, and 50℃ in polypropylene plastic packaging for 42 days under vacuum conditions. Changes in water content, free fatty acids, flavour, clumping and total microbial number were detected. Results showed that an increase in temperature and shelf life duration can increase the water content and free fatty acid levels and reduce the score on the flavour reception of instant chocolate. Shelf life was estimated based on free fatty acid levels and first-order reactions. The shelf life of instant chocolate stored at 30℃, 40℃, and 50℃ is 281.58, 240.99 and 113 days, respectively
