Abstract:

The American taro rice cake, made by adding fermented glutinous rice and Apios americana Medikus, is a type of functional rice cake. Since the main component of this kind of rice cake is starch, which ages quickly after maturation, the shelf life of rice cakes is generally only 1-2 days.How to extend the shelf life of this kind of rice cake using healthy additives is an urgent issue that needs to be addressed. Inulin is a functional natural oligosaccharide,which has effects on lowering blood lipids and regulating the intestinal environment.Due to its excellent water retention properties, inulin can improve the texture of foods. This study added inulin to the raw materials of rice cake adding fermented glutinous rice and Apios americana Medikus by a single factor experiment and investigated the impact of inulin addition on the quality of the rice cake through sensory evaluation and texture analysis, and determined the shelf life of the rice cake using microbial testing.The results showed that when the inulin content was 3%, the quality of the rice cake was optimal. Adding inulin can slow down the aging process of the rice cakes, better maintain the softness and elasticity of rice cakes. Microbial testing confirmed that the shelf life of rice cake is 4 days.
