Konjac glucomannan is a high-molecular-weight, water-soluble dietary fiber extracted from the tubers of the konjac plant (Amorphophallus konjac), a perennial native to Southeast Asia and long cultivated in China and Japan. For centuries, konjac has been a staple in Asian cuisine, prized for its ability to form a gel-like texture and its traditional use as a digestive aid and satiety enhancer.

Chemically, glucomannan is a polysaccharide composed of β-1,4-linked D-mannose and D-glucose units with branched side chains.

Its exceptional viscosity and gel-forming capacity distinguish it from other dietary fibers, making it a versatile functional ingredient in food, nutraceutical, and pharmaceutical applications.

Our konjac glucomannan is refined to a purity of ≥ 95%, ensuring consistent viscosity and functional performance. It is widely used in weight management supplements, as a thickener in food products, and as a prebiotic in digestive health formulations.
