Starch gelatinization
WebbThis process is known as starch gelatinization and is the reason why during cooking starch becomes a paste of high viscosity. For industrial applications and for some food application, starch is sometimes chemically modified. This includes esterification, etherification and oxidation. WebbAl dente" means "to the foot" 2. Dextrinization is the process of forming dextrins 3. Ingredients added is one of the factors affecting starch paste viscosity and starch gel strength 4. Certain type of starch will influence the characteristics of the starch paste viscosity and gel strength 5. Salt will delay or inhibit gelatinization of starch 24.
