低聚果糖和低聚半乳糖的肠道益生功能研究

Study on Probiotic Function of Fructooligosaccharides and Galacto–oligosaccharides on Intestinal Microflora

益生元低聚糖是一种可被选择性发酵并调节肠道中有益菌群的组成和活性的食物成分。其中功能性低聚糖在人体肠道内可被双歧杆菌和乳酸杆菌等肠道益生菌利用,进而促进肠道益生菌的生长和增殖。采用传统体外培养与体内试验方法,以调节婴儿肠道有益菌群为目的,评价低聚果糖和低聚半乳糖的益生功能。结果表明:两种功能性低聚糖均对肠道有益菌有较好的增殖作用;能有效调节肠道菌群失衡的情况;动物试验中对照组与试验组差别较大。

Prebiotic oligosaccharides is a food composition which can be selectively fermented and it can regulate composition and activity of intestinal flora.Functional oligosaccharides are good substrates for bacteria of the type bifidobacterium and lactobacillus,and can promote the growth and proliferation of intestinal probiotics.This study is useful for the purpose of regulating infant intestinal microflora and evaluating the probiotic function of fructooligosaccharides（FOS） and galacto-oligosaccharides（GOS） by using the traditional culture in vitro and in vivo test.The results show that： two kinds of functional oligosaccharides have probiotic effects and can effectively adjust the balance of intestinal flora.There is difference between two experimental groups.
