Oat Beta Glucan is a kind of polymeric unbranched linear mucopolysaccharide, which contains about 70% of β-(1→4) and 30% of β-(1→3) bonds. In terms of nutrition and processing, the β-glucan solution has unique properties, and people use this physical property to make thickeners and stabilizers. It has been confirmed by numerous studies that β-glucan can lower blood sugar and cholesterol, prevent constipation, reduce the incidence of rectal cancer, promote the reproduction of beneficial intestinal bacteria by fermenting short-chain fatty acids (SCFA), and reduce cardiovascular diseases and prevent diabetes. β-glucan has a large molecular weight and can form a high-viscosity solution when dissolved in water.
