摘要： Grain proteins, lipids, and non-starch polysaccharides form structural barriers, inhibiting starch digestion; heating and in vivo physicochemical processes significantly alter the microstructure of these barriers, reducing their inhibition of starch digestion. Wet and dry heating affect the structural integrity of the barriers in markedly different ways, whereas the structural disassembly of the barriers in oral-gastrointestinal tract largely determines their contribution to starch digestibility. The internal and external factors that affect the structural barriers impeding starch digestion have yet to be thoroughly scrutinized. Here, we review the intrinsic properties of the different scale structural barriers in grains. Specifically, we provide a summary of the effects of wet and dry heating on the structure and function of grain barriers, as well as the mechanical and biochemical degradation of the structural barriers by oral, gastric, and intestinal digestion. This review delves into the regulation of structural barriers in whole grains by heating and in vivo physicochemical processes, and provides valuable strategies for processing slow-digested healthy grains.
