Pendugaan Umur Simpan Biji Kopi Arabika Menggunakan Metode Accelerated Shelf-Life Test (ASLT)dengan Model Arrhenius

Abstract

The high level of coffee consumption in Indonesia is one of the factors that causing an increase in coffee production. The increase in coffee production must be accompanied by maintenance of coffee beans quality, namely by storing and selecting the right type of packaging so as to maintain the quality. A decrease in the quality of coffee beans can cause a decrease in the shelf-life. The shelf-life of coffee beans can be determined based on changes that occur in the quality of the beans during storage using the Accelerated Shelf-Life Test (ASLT) method. Therefore, research on the shelf-life of coffee beans is needed. This study was aimed to estimate the shelf-life of coffee beans using the ASLT method with the Arrhenius model based on caffeine content, moisture content, and taste value parameters. This research was conducted using 4 types of packaging, namely aluminum foil, grainpro, paper, and jute sack, and with 3 temperature levels, namely 30°C, 40°C, and 50°C. From the research conducted, it was found that the ASLT method and Arrhenius model is suitable for estimating the shelf-life of coffee beans, resulting in coffee beans packed with grainpro packaging had the longest shelf life compared to other packaging. With caffeine content as a benchmark, coffee beans can last up to 148 days at 30°C, 59 days at 40°C and 25 days at 50°C. Meanwhile, with moisture content parameter, the beans can last up to 46 days at 30°C, 21 days at 40°C and 11 days at 50°C. In addition, if the taste value is used as a benchmark, the beans can last up to 45 days at 30°C, 21 days at 40°C and 10 days at 50°C.
