Research On The Physiological Functions Of Fructo-oligosaccharide

Fructo-oligosaccharide also known as cane FOS,its molecular structure is on sucrose(GF)molecules to ?-1,2 glycosidic bond of 1 to 3 molecules of fructose.Its composition is mainly kestose(GF2),nystose(GF3)and fructofuranosylnystose(GF4).FOS usually presence in higher plants,especially onion,burdock,asparagus,bananas and other high content of plants.FOS has the function of improving the intestinal flora,anti-caries,promoting mineral absorption,enhancing immunity,improving lipid metabolism,lowering cholesterol and other effects features.The effect of FOS on triglyceride(TG)and total cholesterol(TC)in serum and liver tissue of mice was studied in the experiments,and the adsorption of FOS to lipid under different pH conditions was observed in vitro.At the same time,evaluate the intestinal motility in mice and defecation by studying mice stool,ink advance rate,the first row of black stools time of feces,weight and moisture content.The results are as follows:1.Serum TG of experimental mice content was significantly lower than the control group(P <0.01).Absorption rate of FOS to animal serum cholesterol is 44.98% in hyperlipidemia model.When the pH 3.0,pH 7.0,the FOS has a strong adsorption capacity;pH 7.0,the FOS have a strong adsorption capacity to pairs of peanut oil and cholesterol.2.Advance rate of ink of the mice fed FOS was significantly higher than the model control group,compared with the model group,the first black grains will be significantly shorter,while defecation and weight to be significantly increased,indicating Fructo-oligosaccharide can significantly promote bowel movements,increased fecal grains and weight.
