Fructo oligosaccharides (FOS) is a mixture of oligosaccharides (GF2, GF3, GF4) which are composed of fructose units connected by ß (2-1) 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”.
This product is an excellent prebiotic and soluble dietary fiber as well. It can improve bowel function, prevent constipation and diarrhea. Currently it has been widely used in food, health products and other industries.
