Introduction

Fructose- oligosaccharides(FOS) is a mixture of oligosaccharides (GF2, GF3, GF4) which are composed of fructose units connected by ß (21) links. These molecules are terminated by a fructose unit. The total number of fructose or glucose units (Degree of Polymerization or DP) of oligofructose ranges mainly between 2 and 4.

Fructose-oligosaccharides(FOS), is also know as Fructo- oligo, it directly enters into large intestine without being digested and absorbed by human body, and in intestine it rapidly promotes reproduction of bididobactirium and other probiotics, so it is also called “Bifidus Factor”. 

Application

Crystalline fructose is a monosaccharide, is the most chemically active sugar in sugar, naturally occurring in honey and Jerusalem artichoke, chicory and other composites. Fructose sweet, fruity, low calorie, metabolism faster than glucose in the body, easily absorbed by the body, and does not depend on insulin, little effect on blood glucose, glucose metabolism and liver dysfunction in patients with additional energy. In the human body can promote the growth and reproduction of beneficial bacteria such as bifidobacteria, inhibit the growth of harmful bacteria, improve gastrointestinal function and metabolism, reduce blood lipids, not dental caries, diabetes, obesity patients, children's food ideal sweetener.
