Description
Curdlan is a high molecular weight linear polymer made up of β-(1->3)-linked glucose residues, which is produced as a water-insoluble polysaccharide by the soil bacterium, Alcaligenes faecalis. It is a type of polysaccharide that can form both hard and elastic, thermally irreversible gels and thermally reversible gels, and is commonly used as a food additive for its gelling and thickening properties. Its applications extend to the production of biomedical materials, drug delivery systems, cosmetics, paints, and other industrial products.
