| Abstract: | Starch is a granular mixture of nomopolymers of α-D-glucopyranosyl units. These polymer molecules are hydrogen bonded and aligned radially in the granule. Starch is an important ingredient in manufacturing a wide range of industrial products such as food, paper, textiles, and building materials. Today, starch is chemically modified for speciality use. Modification of starch properties by derivatization is an important factor in the continued and increased use of starch to provide thickening, gelling, binding, adhesive, and film forming functionality. Carboxymethylstarch (CMS) is one of important starch derivatives. The study in exploitation and use of CMS has been acitvated since 1980s. At present, it is widely used in medicine, functional food, commodity, dope and so on. |
