Stachyose
From Wikipedia, the free encyclopedia
Stachyose is an oligosaccharide (tetrasaccharide) consisting of two D-galactose units, one D-glucose unit, and one D-fructose unit sequentially linked. Its molecular weight is 666.6 g/mol. Stachyose is naturally found in many vegetables (e.g. green beans, soybeans and other beans) and plants.
Stachyose is less sweet than sucrose, with about 28% on a weight basis. It is mainly used as a bulk sweetener or for its functional oligosaccharide property. Stachyose is not completely digestible by humans and deliver 1.5 to 2.4 kcal/g (6 to 10 kJ/g).
