目的探讨一种活性乳酸菌饮料对人体肠道菌群的影响作用。方法采用卫生部《保健食品检验与评价技术规范》调节肠道菌群功能检验方法进行检验。结果试食组试验前后自身比较:肠道内双歧杆菌、乳杆菌数量明显增加(P<0.01),肠球菌数量增加(P<0.05),产气荚膜梭菌数量明显减少(P<0.01),肠杆菌和拟杆菌无明显变化;试验后对照组与试食组组间比较:双歧杆菌数量明显增加(P<0.01),乳杆菌的数量增加(P<0.05),肠杆菌、肠球菌、产气荚膜梭菌和拟杆菌无明显变化。结论活性乳酸菌饮料具有调节人体肠道菌群、改善肠道内环境的作用。
Objective To investigate the effect of an active lactobacillus beverage on human intestinal microflora. Methods The Ministry of Health “health food testing and evaluation of technical specifications” to regulate intestinal microflora functional test methods for testing. Results The number of Enterobacter cloacae and Enterobacter cloacae significantly increased (P <0.01), the number of enterococci increased (P <0.05) and the number of Clostridium perfringens significantly decreased (P <0.01) (P <0.01), the number of Lactobacillus increased (P <0.05), enterobacteriaceae, Enterobacter and Bacteroides spp. No significant changes in the test group; , Clostridium perfringens and Bacteroides no significant change. Conclusion The active lactic acid bacteria beverage has the function of regulating the human intestinal flora and improving the intestinal environment.
