ESTIMATION OF THE SHELF LIFE OD DRY COCOA BEANS (Theobroma cacao) USING THE ACCELERATED SHELF LIFE TESTING (ASLT) ARRHENIUS MODEL METHOD
Keywords:
cocoa beans, shelf life, ArrheniusAbstract
The purpose of this study was to estimate the shelf life of dried cocoa beans (Theobroma cacao) using the Accelerated Shelf Life Testing (ASLT) method with the Arrhenius model approach. The cocoa beans were packed in two types of packaging—jute sacks and plastic bags—and stored at three different temperatures (20°C, 30°C, and 40°C) for a period of 28 days. Quality parameters such as moisture content and free fatty acid (FFA) levels were analyzed, and sensory evaluations were conducted to assess organoleptic attributes during storage. The findings indicated that storage temperature and packaging type significantly affected the increase in moisture and FFA content. These parameters increased over time, especially under higher temperatures. The Arrhenius model showed that the rate of quality degradation followed a zero-order reaction. Based on the rate of moisture increase, the estimated shelf life of cocoa beans stored in jute sacks was 145,013 weeks (1.015 days) at 20°C, 35,359 weeks (247 days) at 30°C, and 9,528 weeks (67 days) at 40°C. For plastic packaging, the longest shelf life was obtained at 20°C with 22,043 weeks (154 days), followed by13,614 weeks (95 days) at 30°C, and 8,671 weeks (60 days) at 40°C. The best shelf life was achieved with jute sack packaging at 20°C. This study concludes that the ASLT method with the Arrhenius model is effective for predicting the shelf life of dried cocoa beans and highlights the significant impact of packaging type and temperature on product quality retention.
