Food Science and Human Wellness 2025年

作者： wei-yi zhang Yang Yang Chun-min Ma Bing Wang Xiao-fei Liu Yan Wang Xin Bian Guang zhang na zhang College of Food Engineering， Harbin University of Commerce

Resistant starch (RS) comprises starch fractions that resist digestion in the small intestine and reach the colon， where they are fermented by the microbiota. Resistant starch harbors functional properties and health-promoting ingredients that can regulate blood glucose and lipid levels， prevent cancer， and enhance the quality of life. Consequently， new technologies for the preparation of RS are continually being developed to support its industrial production. This review describes the structural and nutritional properties of RS and examines recent advancements in RS preparation methods. Emphasis is placed on how RS structure influences its properties and the physiological mechanisms in vivo. This review aims to stimulate further research into the preparation methods， functional characteristics， and utilization of RS， thereby supporting ongoing developments in the food industry.
