Product Overview

-CAS No:308066-66-2

-MF: C6H12O6


-H.S Code:17029000

Physical Properties

Fructooligosaccharides(FOS)90/95 Powder made from sucrose by Fermentation process which is natural food fiber.FOS (Fructose-oligosaccharides) 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.

Processing properties of FOS as an Ingredient
 - Sweetness of FOS is 0.3-0.6 times of sucrose.
 - FOS is very soluble in water and more soluble than sucrose.
 - It does not crystallize, precipitate or leave a dry or sandy feeling in the mouth.
 - Viscosity is relativity higher than sucrose.

Stability of FOS
In very acid conditions, significant exposure times and temperatures, FOS may hydrolyse into fructose. FOS is more sensitive to acid hydrolysis. This makes the use of FOS in highly acidic ambient products with a long shelf life such as soft drinks rather difficult. In most other applications, such as industrial fruit preparations and fresh fruit juices, the hydrolysis can be limited by controlling the process.
