The invention discloses composite
modified starch for replacing fat as well as a preparation method and application of the composite
modified starch, and belongs to the field of
modified starch foods.The preparation method of the composite modified
starch comprises the following steps: (1) size mixing; (2) alkalization; (3) crosslinking; (4) primary esterification; (5) secondary esterification; (6) washing and
dewatering; (7) pre-gelatinization treatment. The composite modified
starch product produced by the invention has
viscosity, emulsibility and stability similar to those of fat; the composition has good compatibility and foam retention with essence, spices and other seasonings; compared with fat, the product has better processability,
high resistance to high-concentration acid, sugarand salt and high
mechanical resistance, can effectively reduce the application of fat in dairy products, frozen desserts, sauces, salad dressings, meat products, baked foods, chewing gums and candies, and achieves the purpose of reducing the production cost; the composition has the characteristic of being soluble in cold water, can be compounded with other products for use in the use process andis convenient to use.
