Pre-gelatinized starch, a specially processed modified starch, possesses multiple excellent characteristics and a wide range of applications. This article introduces the preparation methods, properties, and applications of pre-gelatinized starch in various industries.

　　The preparation methods of pre-gelatinized starch mainly include physical and chemical methods. The physical method uses physical means such as grinding and sieving to break down starch granules into smaller particles. Although simple and easy to implement, the pre-gelatinized starch produced has uneven particle sizes and low production efficiency. In contrast, the chemical method involves adding an appropriate amount of cross-linking agent to form cross-links between starch molecules, thereby reducing the starch particle size, resulting in uniform particle size and higher production efficiency. These two methods each have advantages and disadvantages, and the appropriate preparation method can be selected according to specific needs.

　　Pre-gelatinized starch has many excellent properties, such as thickening, stability, adhesion, and film-forming properties. These properties allow it to play an important role in many fields. For example, its thickening property can be used to improve the taste and texture of food; its stability helps maintain the long-term quality of products; its adhesion makes it an important auxiliary material in the pharmaceutical and papermaking industries; and its film-forming property has broad application prospects in the cosmetics and textile industries.

　　Application Fields of Pre-gelatinized Starch

　　Food Industry: In the food industry, pre-gelatinized starch can be used as a thickener, stabilizer, and texture modifier in the production of foods such as ice cream, jams, and bread. Its excellent thickening and stability properties help improve the quality and taste of food.

　　Pharmaceutical Industry: In the pharmaceutical industry, pre-gelatinized starch can be used as a drug carrier and disintegrant, improving drug solubility and bioavailability. Its adhesive and disintegrating properties aid in the release and absorption of drugs in the body.

　　Papermaking Industry: In the papermaking industry, pre-gelatinized starch can be used as a paper coating agent and reinforcing agent to improve the quality and performance of paper. Its film-forming and adhesive properties help improve paper strength and surface quality.

　　Textile Industry: In the textile industry, pre-gelatinized starch can be used as a fabric softener and wrinkle-resistant agent to improve the feel and appearance of fabrics. Its film-forming and lubricating properties help enhance the wearing comfort and aesthetics of fabrics.

　　Cosmetics Industry: In the cosmetics industry, pre-gelatinized starch can be used as a thickener and stabilizer in cosmetics to improve the stability and effectiveness of cosmetics. Its excellent thickening and stability properties help maintain the texture and quality of cosmetics.

　　In summary, pre-gelatinized starch, as a multifunctional modified starch, has broad application prospects in various fields such as food, pharmaceuticals, papermaking, textiles, and cosmetics. With continuous technological advancements and expanding application fields, the production technology and application methods of pre-gelatinized starch will continue to innovate and develop. At the same time, we should also pay attention to potential safety issues to ensure compliance with safety standards and regulations during use.
