后生元及其在乳制品中的应用研究进展

后生元是近年来出现的一种干预肠道生态系统的新手段.后生元是指由活细菌分泌或细菌裂解后释放的可溶性因子(产物或代谢副产物),如酶、肽、磷壁酸、肽聚糖衍生的多肽、多糖、细胞表面蛋白和有机酸等可调控宿主健康的小分子.尽管目前国际益生菌和益生元科学协会尚未发表关于后生元的共识,但作为与益生菌密切相关的概念依旧引起了人们的关注....

Recent Progress in Postbiotics and Their Applications in Dairy Products

Postbiotics are a new means of intervention in the intestinal ecosystem that has emerged in recent years. Postbiotics refer to soluble factors (products or metabolic by-products) secreted by living bacteria or released after bacterial lysis, namely small molecules that regulate the health of the host, such as enzymes, peptides, teichoic acid, peptides derived from peptidoglycan, polysaccharides, cell surface proteins, and organic acids. Although the International Symposium of the International Scientific Association for Probiotics and Prebiotics has not yet published a consensus on postbiotics, this concept closely related to probiotics still attracts people’s attention. This paper briefly clarifies the classification and preparation methods of postbiotics, and discusses the advantages and potential application of postbiotics as functional ingredients in dairy products.
