木糖醇益生功能研究进展

Research progress on probiotic function of xylitol

木糖醇是食品中一种优良的功能性甜味剂替代品。膳食中的木糖醇被胃肠直接吸收的量很少,大量的木糖醇被肠道微生物消化,在肠道中通过微生物发挥的作用不容小觑。木糖醇对人体肠道内的有益菌有显著的增殖作用,同时能够抑制致病菌,具有改善肠道微生态、促进宿主健康的益生功能。文章综述了目前国内外的学者有关木糖醇对肠道微生物的影响研究,并对代谢机制、研究方法进行了简要概述,同时讨论了存在的问题及未来的研究方向,旨在为木糖醇在食品中的进一步研究提供理论参考。

Xylitol is an excellent functional sweetener substitute in food.Small amount of xylitol in the diet is directly absorbed by the gastrointestinal tract,and a large amount of xylitol is digested by gut microbes.Therefore,the role played by gut microbes cannot be underestimated.Xylitol has a significant proliferation effect on beneficial bacteria in human intestinal tract,while inhibiting pathogenic bacteria,and has a probiotic function of improving intestinal microecology and promoting host health.This article reviews the current research on the effects of xylitol on intestinal microbes by scholars,and gives a brief overview of metabolic mechanisms and research methods.At the same time,the existing problems and future research directions are also discussed,aiming to provide a theoretical reference for the further research of xylitol in food.
