FOS

Sweetener Natural sugar Oligofructose (FOS) are a mixture of oligosaccharides (GF2, GF3, GF4), which are composed of fructose units connected by ß (2-1) links. These molecules are terminated by fructose units. The total number of fructose or glucose units (degree of polymerization or DP) of fructo oligosaccharides is mainly between 2-4. Fructo oligosaccharide (FOS), also known as fructo oligosaccharide, enters the large intestine directly without being digested and absorbed by the body, and rapidly promotes the reproduction of bifidobacteria and other prebiotics in the intestine, so it is also called fructo oligosaccharides . "Bifidus Factor".
