Process for making a thermal converting starch by modification of oxidized starch with aluminum salts

摘要

Process for preparing a thermal converting starch by reacting an alkaline hypochlorite oxidized starch with a water soluble aluminum salt. The treatment provides a starch product which when pasted at high temperatures will degrade to give a low viscosity material. The process includes the steps of slurrying oxidized starch in water and treating the oxidized starch with a water soluble aluminum salt.
