Pregelatinized starch, a modified starch, plays a vital role in modern pharmaceutical, health product, and food industries. Its unique physical and chemical properties allow pregelatinized starch to be used in many fields.

　　Pregelatinized starch is obtained by chemically or mechanically breaking down starch granules partially or completely. This modification gives the starch better flowability and direct compressibility, facilitating its use in pharmaceutical preparations and food processing. Pregelatinized starch appears as a white or off-white powder, odorless, with a slightly unique taste, making it well-accepted in various applications.

　　In the pharmaceutical field, pregelatinized starch has wide applications. As a binder for oral tablets and capsules, it effectively solidifies and binds drug ingredients. Pregelatinized starch can also serve as a diluent and disintegrant, aiding drug release and absorption in the body. Due to its non-toxic and non-irritating properties, pregelatinized starch is widely recognized in the pharmaceutical field.

　　In pharmaceutical preparations, the recommended dosage of pregelatinized starch varies depending on the type of preparation. For example, as a diluent in capsules, the recommended dosage is 5-75%; as a direct compression binder, the recommended dosage is 5-20%; and as a wet granulation binder and tablet disintegrant, the recommended dosage is 5-10%. These recommendations are based on extensive experimental research and practical production experience, ensuring the quality and stability of pharmaceutical preparations.

　　Besides the pharmaceutical field, the application of pregelatinized starch in the food industry is also expanding. Current research explores its application in pressed candies, compressible foods, etc. These studies indicate that pregelatinized starch has potential roles in improving food texture and taste. Due to the complexity and diversity of the food industry, the specific application of pregelatinized starch in food processing requires further research and exploration.

　　In summary, pregelatinized starch, as a multifunctional modified starch, has broad application prospects in the pharmaceutical and food industries. With continuous technological advancements and expanding application areas, pregelatinized starch will play an even more important role in the future.
