Pre-gelatinized starchMain functions: 1. Adhesive function 2. Tensile strength 3. Impact resistance 4. Tear resistance 5. Waterproof performance 6. Acid and alkali resistance.

　　Pre-gelatinized starchIt is made by gelatinizing starch, then drying and pulverizing. It belongs to starch and is newly prepared. Personally, I think it improves viscosity, superior to starch. Pre-gelatinized starch is a modified starch obtained by partially or completely breaking down starch granules through chemical or mechanical methods. It is often used as a binder, diluent, and disintegrant in tablets. Pre-gelatinized starch has a self-lubricating effect, and magnesium stearate should be added as a lubricant when used with other excipients. Pre-gelatinized starch is harmless and non-irritating.

　　Pre-gelatinized starch is a white or grayish-white powder, odorless, with a special taste. In the pharmaceutical field, it is often used as a binder, diluent, and disintegrant for oral tablets and capsules. In the pharmaceutical field, pre-gelatinized starch is used as a binder, diluent, and disintegrant for oral capsules and formulations. Compared with starch, pre-gelatinized starch can increase fluidity and compressibility and can be used as a binder in dry granulation tableting processes. Among them,Pre-gelatinized starchit has a self-lubricating effect. The solubility of pre-gelatinized starch is insoluble in organic solvents, slightly soluble or soluble in cold water, depending on the degree of gelatinization. Screening pre-gelatinized starch into stirred cold water yields a starch paste; the solubility of some pre-gelatinized starch in cold water is 10-20%.

　　UsagePre-gelatinized starchPrecautions:

　　1. Pre-gelatinized starch storage methods should pay attention to storing in a cool, dry, and ventilated place;

　　2. When using a dry binder to directly press the powder, try to use as little alkali metal salt of stearic acid (such as magnesium stearate) as a lubricant as possible to avoid affecting the hardness of the tablets. If necessary, stearic acid can be used as a lubricant, which has a smaller adverse effect on the hardness of the tablets.
