Two varieties of rice crackers PRACTICAL APPLICATIONSFor a low-moisture food product, actual storage testing by a long-term stability study involves storing a packaged product under typical storage conditions and examining the product at regular time intervals. costly and time consuming, since most low-moisture food products have a shelf-life of several weeks or even months. This paper describes the shelf-life prediction of two varieties of rice crackers having different compositions using a simulation model based on the relationship between barrier property of the packaging materials and moisture adsorbed by the rice crackers determined by the Guggenheim-Anderson-de Boer (GAB) model. The shelf-life simulation provides a powerful support tool for shelf-life estimation and packaging development.
