Classification of modified starches
At present, there are more than two thousand varieties and specifications of modified starch. The classification of modified starch is generally based on the treatment method.(1) Physical denaturation: pre-dextrinised (alpha-ized) starch, gamma-ray, ultra-high frequency radiation treated starch, mechanical grinding treated starch, moist heat treated starch, etc.(2) Chemical denaturation: denatured starch obtained by treatment with various chemical reagents. There are two major categories: one is to make the molecular weight of starch decrease, such as acid-decomposed starch, oxidized starch, baking dextrin, etc.; the other is to make the molecular weight of starch increase, such as cross-linked starch, esterified starch, etherified starch, grafted starch, etc.(3) Enzymatic denaturation (biological modification): various enzymes treat starch. Such as α, β, γ-cyclodextrin, maltodextrin, straight chain starch, etc.(4) Compound denaturation: denatured starch obtained by using two or more treatment methods. Such as oxidized cross-linked starch, cross-linked esterified starch, etc. The modified starch obtained by compound denaturation has the respective advantages of two kinds of modified starch.

Preparation of preparations of starch
Starch in formulation preparation Overall, starch is water-insoluble, water-dispersible and swells at 60-70°C. It is often used as a diluent, binder, disintegrant and can be used to prepare dextrins and...
