益生元及其应用研究进展

Research Progress of Prebiotics and Their Application

益生元通常是指一些多糖、低聚糖、微藻类、天然植物等,来源比较广泛。新兴的益生元主要在藻类、果汁、果皮、种子、中药、微生物中被发现,涉及多糖、多酚、多肽聚合物等。益生元可选择性地刺激特定肠道菌的生长,具有改善肠道微生态、调节免疫、抵抗病原体、影响代谢、增加矿物质吸收、增强机体健康等功能,涉及领域有医疗保健、食品、化妆品和畜牧养殖等。此外,益生元与益生菌通常可结合使用,发挥协同功效。本文主要综述益生元、新兴益生元及益生元应用现状,为进一步深入研究其应用和功效提供理论参考。

Prebiotics usually refer to some polysaccharides,oligosaccharides,microalgae,natural plants,etc.,which have a wide range of sources.New prebiotics are mainly found in algae,fruit juice,pericarp,seeds,traditional Chinese medicine,microorganisms,involving polysaccharides,polyphenols,polypeptide polymers,etc.Prebiotics can selectively stimulate the growth of specific intestinal bacteria,improve the intestinal microecology,regulate immunity,resist pathogens,affect metabolism,increase mineral absorption,and enhance body health.The fields involved include medical care,food,cosmetics and animal husbandry,etc.In addition,prebiotics and probiotics can usually be used in combination to achieve synergistic effects.This article mainly reviews the status quo of prebiotics,emerging prebiotics and application of prebiotics,and provides theoretical reference for further research on application and efficacy of prebiotics.
