后生元的功能及应用研究进展

Function and Application of Postbiotics:A Review

后生元是指给宿主带来健康益处的无生命的微生物或其成分的制剂,是微生态制剂领域的新兴概念。后生元具有平衡肠道菌群、增强肠道上皮屏障功能、增强免疫调节和促进新陈代谢等多种功效,并且具有稳定性高、安全性高以及易储存等优点,使其在食品、保健品、化妆品、饲料等领域应用前景广阔。目前对后生元的研究和开发应用尚处于起步阶段,在阐明活性成分及剂量、明确作用机制及靶点,以及制定相应的法规与标准等方面仍需进行更深入的探索。该文从后生元的功能特性、制备方法、鉴定方法、市场应用等方面进行阐述,为后生元的研究及开发应用提供参考。

Postbiotic,a new concept in the field of microecologics,refers to the preparation of inanimate microorganisms and/or their components that confer a health benefit on the host.With functions such as balancing intestinal flora,enhancing intestinal epithelial barrier function and immune regulation,and promoting metabolism,it has the advantages of high stability,high safety,and easy storage,allowing it to be widely used in food,health care products,cosmetics,feed,and other fields.At the moment,the research,development and application of postbiotics are still at the initial stage,and more efforts should be made to clarify the active ingredients,dose,mechanism of action,and targets,and formulate sound relevant regulations and standards.In this paper,the functional characteristics,preparation methods,identification methods and market application of postbiotics were reviewed,which can provide convincing reference for the research,development,and application of postbiotics.
