Analog rice is rice made from some or all non-rice ingredients and was created as a food diversification product so that it can be an alternative staple food to replace rice produced from rice. The shelf-life of food products can be determined using the ASLT method, which in principle accelerates the rate of deteriorating quality of stored products measured by selected critical parameters, such as color, aroma or moisture content. The aim of this research was to establish critical parameters and determine the shelf-life of analog rice made from porang glucomannan flour without packaging and with vacuum packaging. In this study, the critical parameters for the shelf-life of analog rice were the moisture content and the degree of whiteness. Based on the results, the parameter with the lowest activation energy was the moisture content, and thus had the most influence on the deterioration of analog rice samples. The shelf-life of unpackaged analog rice at 35° was found to be 50.32 days while the shelf-life of vacuum-packed analog rice at the same temperature was 150.82 days. The results show that vacuum packaging could considerably improve the shelf-life of analog rice
