The alkalinity of acidified starch was determined by acid - base titration. The degree of substitution of carboxymethyl starch was determined by complexometric titration. The carboxyl group and carbonyl group in oxidized starch were determined by hot - drop titration and hydroxylamine method. Cation starch was determined by digestion and nitrogen determination. Starch group analysis method. The principle of classic, fast, accurate, for production practice, to obtain satisfactory results.
