Carboxymethyl starch sodium industrial grade modified starch

Carboxymethyl starch Sodium carboxymethyl starch, also known as carboxymethyl starch, is an anionic starch ether with the chemical formula [C10H19O8Na]n. It is a white or yellow powder and is an electrolyte that is soluble in cold water. It is a kind of modified starch and belongs to ether starch, which is a water-soluble anionic polymeric compound. It is tasteless, non-toxic, not easy to mold, and easily soluble in water when the degree of substitution is more than 0.2. Properties It is usually used as its sodium salt, also known as (CMS-Na) Shape: White or yellow powder, odorless, tasteless, non-toxic, heat-absorbent. Soluble in water to form colloidal solution, stable to light and heat. Insoluble in ethanol, ether, chloroform and other organic solvents. The aqueous solution is more stable in alkali and less stable in acid, generating free acid insoluble in water and reducing viscosity, so it is not suitable for strongly acidic food. When the aqueous solution is heated above 80℃ for
