摘要：
Adsorption isotherms of gari (cassava semolina) were determined at 15, 25 and 35-degrees-C, and the Guggenheim, Anderson and de Boer (GAB) isotherm model was applied to the data. At high water activities, the moisture content increased with rise in temperature, resulting in crossing of the isotherms at a(w) between 0.5 and 0.7. This sorption phenomenon can be explained by changes occurring in the starch structure and modifying the availability of water adsorption sites. Estimated shelf-lives of gari are calculated and recommendations for its packaging and storage conditions are given.
