燕麦β-葡聚糖的分子结构特点及其生物学功能研究进展

Research Progress on Molecular Structure and Biological Functions of Oatβ-Glucan

燕麦β-葡聚糖是存在于燕麦胚乳和糊粉层细胞壁的一种非淀粉多糖。文章从燕麦β-葡聚糖的结构特征、含量、生物学功能及其在食品中的应用等方面进行归纳和总结。重点阐述了燕麦β-葡聚糖降胆固醇、降血糖、改善肠道菌群及抗氧化方面的作用,期望能为燕麦β-葡聚糖作为食品功能因子进行深度开发及利用提供科学依据。

Oatβ-glucan is a non-starch polysaccharide which exists in the endosperm and aleurone cell wall of oat.In this paper,the structural characteristics,content,biological functions and application ofβ-glucan in oat are summarized.The effects of oatβ-glucan on lowering cholesterol,lowering blood sugar,improving intestinal flora and antioxidation are discussed,hoping to provide scientific basis for the further development and utilization of oatβ-glucan as a food functional factor.
