低聚果糖沙棘红茶粉调节肠道菌群人体试验研究

Human Experimental Study on Regulation of Intestinal Flora by Fructooligosaccharide Seabuckthorn Black Tea Powder

研究低聚果糖沙棘红茶粉调节人体肠道菌群的保健功能。采用自身对照及组间对照设计,试食组食用低聚果糖沙棘红茶粉,连续食用15 d;对照组采用空白对照组。观察受试者试食前后肠杆菌、肠球菌、产气荚膜梭菌、拟杆菌、乳杆菌、双歧杆菌数量。试食后试食组乳杆菌和双歧杆菌数量与试食前比较均有增加,差异有显著性(P<0.01);试食后试食组乳杆菌和双歧杆菌数量显著高于对照组(P<0.05);试食后产气荚膜菌减少(P<0.05),肠杆菌、肠球菌、拟杆菌数量均无明显变化。两组受试者试食后血压、心率、血、便、尿常规和血生化指标等均无明显异常改变,试食期间未观察到明显不良反应。低聚果糖沙棘红茶粉具有调节人体肠道菌群的保健功能。

Study the health function of fructose-oligosaccharide sea buckthorn black tea powder in regulating human intestinal flora.Self-control and intergroup control design were used.The test group was fed fructose-oligosaccharide sea buckthorn black tea powder for 15 days.The control group was a blank control group.The quantity of enterobacterium,enterococcus,clostridium perfringens,bacteroides,lactobacillus and bifidobacterium were observed before and after the test.The quantity of lactobacillus and bifidobacterium in the test group increased significantly after the trial compared with that before the trial(P<0.01).The number of lactobacillus and bifidobacterium in test group was significantly higher than that in control group(P<0.05).The number of perfringens decreased(P<0.05),and the number of enterobacter,enterococcus and Bacteroides had no significant change.There were no significant abnormal changes in blood pressure,heart rate,blood,stool,urine routine and blood biochemical indexes after the test,and no obvious adverse reactions were observed during the test.Fructooligosaccharide seabuckthorn black tea powder has the health function of regulating human intestinal flora.
