摘要
谷物β-葡聚糖是β-D-吡喃葡萄糖单位通过β-(1→4)键重复连接,再被单一的β-(1→3)键分开而成的无分支线性葡萄糖聚合物,是一种重要的水溶性膳食纤维,主要存在于大麦、燕麦和小麦中。谷物β-葡聚糖在降血糖、血脂,提高免疫活性及改善肠道健康等方面生理活性显著,已广泛应用于食品和化妆品等领域。本文综述了谷物β-葡聚糖的提取纯化、结构特征、含量测定、理化性质、生物活性及其应用,为谷物β-葡聚糖的进一步研究和开发提供参考。
Cereal fi-glucans are a type of linear glucose polymers containing oligosaceharides which are formed by the linkage of β- D- glucopyranosyl units via （ 1→4 ） -β- linkage and separated by single （ 1 →3 ） -β- linkages. They were mainly found in barley,oat and wheat as an important water-soluble dietary fiber.Cereal β-glucans had been widely used in food and cosmetic industries. Due to their significantly physiological activities such as hypoglycemic activity, hypolipidemic activity, immunomodulating and intestinal health,thus,this review focused on the extraction and purification, structural characterization, content measurement,physicoehemieal properties,bioaetivities and applications of cereal β-glucans with the aim of providing reference for further studies.
