Slowly Digestible Starch

Slowly digestible starch (SDS) is digested within 20–120 min in the human body, resulting in the slow and prolonged release of glucose into the bloodstream, coupled to a low glycemic response. The potential benefits of SDS are linked to stable glucose metabolism, diabetes management, mental performance, and satiety. SDS can be widely used in solid or liquid processed food products, nutritional supplements, and drug preparations. Future research should focus on the stabilization and protection of flavors, lipids, bioactive agents, and drugs from oxidation and enzyme hydrolysis. In this chapter, the preparation, structures, physicochemical properties, functions, and potential applications of SDS were reviewed.
