Curdlan gum is water insoluble glucan.Curdlan is a new microbial extracellular polysaccharide, which has the unique property of forming inverse gel under heating condition.Curdlan gum is a kind of extremely safe polysaccharide additive which can not be digested by human body and produce no calories. Structure Curdlan complete molecular formula is C6H10O5, Its molecular weight is about 44,000 ~ 100000 and it has no branched structure. Its primary structure is a long chain. Curdlan can form a more complex tertiary structure due to intermolecular interaction andhydrogen bonding. Character Curdlan suspension can form a colorless, odorless, odorless gel by heating. Besides heating, other conditions are required at the same time such as cooling after heating, specified PH ,Sucrose concentration. Performance characteristics Curdlan is insoluble in water and many organic solvents. Soluble in lye, formic acid, dimethyl sulfoxide,and soluble in aqueous solution o…
