The whole grain dietary fiber structures are an important factor affecting the gastrointestinal health, oats is a healthy whole grain rich in dietary fiber. Studies have shown that thermal processing can affect the characteristics and structures of the DF, however, the structural changes of the whole-grain oats DF with differ-ent thermal processing methods and its impact on the gastrointestinal health have been rarely studied. This paper reviews the mechanism of thermal processing causing oats DF structural changes, express the relationship of DF structure and gastrointestinal healthy.%全谷物膳食纤维(Dietary Fiber,DF)结构变化是影响胃肠道健康的重要因素,燕麦是一种含有丰富DF的健康全谷.一系列研究表明热加工可以影响DF的结构性质,但不同热加工方式下全谷燕麦膳食纤维的结构变化及其对胃肠道健康的影响鲜见系统研究.综述不同热加工方式下全谷燕麦膳食纤维的结构变化及其胃肠道健康效应的影响.
