Abstract
The invention discloses a dual derivatizing process for the preparation of cold water swelling starches and foodstuffs thickened therewith. The starch base is first subjected to a primary crosslinking reaction using sodium trimetaphosphate (STMP) according to conventional techniques, then reslurried, treated with additional STMP and drum dried to effect a secondary crosslinking reaction in situ.
