The general method for preparing pregelatinized wheat starch involves adding surfactants to the surface of starch granules and subjecting them to appropriate heat treatment; this causes the granules to gelatinize, thereby forming pregelatinized starch. Currently, the preparation of pregelatinized wheat starch can also be achieved using microwave radiation heating, a method that offers shorter heating times and greater operational convenience.
Moisture Retention and Freeze Prevention: Pregelatinized wheat starch acts as a humectant in food products-such as ice cream, desserts, and bread-helping to retain moisture and prevent the formation of ice crystals.
Increased Viscosity and Enhanced Stability: In condiments and infant foods, pregelatinized wheat starch serves as a stabilizer, increasing the viscosity and overall stability of the finished products.
Replacement for Gums: Pregelatinized wheat starch can effectively replace the role of gums in foods such as soups and sauces, thereby mitigating any potential adverse health effects associated with the consumption of gums.
