Inulin is most often extracted from sunchoke and chicory root. It is a group of polysaccharides that are primarily long chains of fructose with a few glucose units. Inulin is considered as a functional food ingredients since it can affect physiological and biochemical processes in human beings, resulting in better health and reduction in the risk of many diseases. The soluble fiber is often incorporated into processed foods to add fiber, bulk and a sweet flavor. Inulin can also be used for the preparation of oligofructose and fructose syrups.

1, control blood lipid
Ingestion of inulin can effectively reduce serum total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C), increase the ratio of high-density lipoprotein to low density lipoprotein, and improve the blood lipid status.
2, reducing blood sugar
Inulin is a carbohydrate that does not cause a rise in glucose in the urine. It does not be hydrolyzed to monosaccharide on the upper part of the intestine, so it does not raise blood sugar levels and insulin levels. Now studies have shown that the decrease of fasting blood sugar is the result of the short chain fatty acids produced by fructo oligosaccharides in the colonic fermentation.
3, promoting mineral absorption
Inulin can greatly improve the absorption of minerals such as Ca2+, Mg2+, Zn2+, Cu2+ and Fe2+.
4. regulate intestinal microflora, improve intestinal health and prevent constipation
Inulin is a natural water-soluble dietary fiber, which can hardly be hydrolyzed and digested by gastric acid. It is only used in the colon by beneficial microorganisms, so as to improve the intestinal environment. Body immunity. [5]
5. inhibit the production of toxic fermented products, protect the liver, prevent colon cancer
The food was digested in the intestine to the colon, saprophytic bacteria (Escherichia coli and Bacteroides) effect, can produce many toxic metabolites (such as ammonia, nitrosamines, phenol and p-cresol, secondary bile acid), short chain fatty acid and inulin in colon fermentation can be reduce colon pH, inhibit the growth of saprophytic bacteria, reduce the generation of toxic products, reduce the stimulation of the intestinal wall.
6. the prevention of constipation and the treatment of obesity dietary fiber reduces the stay time of food in the stomach and intestines, and increases the amount of feces, effectively treating constipation. Its weight loss effect is to improve the viscosity of the contents, reduce the speed of food from the stomach into the small intestine, and thus reduce the hunger and reduce the food intake.

7. inulin has a small amount of 2-9 oligosaccharides,
