Konjac glucomannan (KGM) is a neutral polysaccharide derived from the tuber of Amorphophallus konjac. It is composed of β-(1,4)-linked D-mannose and D-glucose with the ratio of 1.6 : 1, with about 1 glycosyl residue in 19 units being acetylated. Because of its excellent properties, such as thickening, gelatin, and biological compatibility, KGM has been widely used in food additives, pharmaceuticals, biotechnology, and the fine chemical industry. And the derived low-molecular-weight konjac glucomannan has been found to have some special biological functions, such as prebiotics, drug carriers, immunoregulation and suppresses IgE production in mice B cells.
