Applications in the Food Industry:
Rapid dissolution and strong binding properties are the primary characteristics of pre-gelatinized starch. Consequently, it is well-suited for applications where time constraints are critical. In the food industry, it can be utilized to eliminate the need for heat treatment in products requiring thickening or shape retention; it can also improve the quality of pastries and stabilize the internal structural integrity of frozen foods. In the food sector, pre-gelatinized starch is predominantly used in the production of soft puddings, savory fillings, gravies, dehydrated soup mixes, seasonings, and fruit-flavored soft candies.
Applications in Eel Farming
Eel feed typically takes the form of pellets, composed of a nutrient-rich powder (containing vitamins and other essential elements), a specific proportion of binders, and fats. The binder component within this mixture must possess the following characteristics: ① Non-toxic, easily digestible, and nutritious; ② Transparent; ③ Capable of maintaining the pellet's structural integrity until it is completely consumed by the eels; ④ Resistant to dissolution by solutes present in the water; and ⑤ Non-adhesive to processing equipment. Pre-gelatinized potato starch serves as the optimal binder for eel feed, typically incorporated at an inclusion rate of 20%.
Applications in the Cosmetics Industry: Talcum powder is a widely used skincare product, traditionally formulated using talc, starch, and various auxiliary ingredients. Currently, manufacturers abroad are utilizing gelatinized starch to replace conventional talc and starch in the production of novel talcum powders. In addition to possessing the standard attributes of ordinary talcum powder, these new formulations exhibit superior skin affinity and exceptional water-absorbing capabilities.
Applications in the Pharmaceutical Industry
Conventional Western-style medicinal tablets typically consist of active pharmaceutical ingredients, starch-based binders, lubricants, and other excipients. In such formulations, the starch primarily serves as a bulking agent to ensure proper mass balance. Newer tablet formulations, however, are composed of active ingredients, pre-gelatinized starch, and lubricants. In these modern formulations, the gelatinized starch functions not only as a bulking agent but also as a primary binder. This approach effectively minimizes unnecessary side effects that may arise from the inclusion of additional, separate binding agents. Consequently, tablets produced using this novel formulation not only satisfy rigorous medical standards but also exhibit superior structural strength post-compression, ease of digestion and dissolution upon ingestion, and an absence of toxic side effects.
Applications in Other Industries
The characteristic of pre-gelatinized starch-that it dissolves rapidly in cold water to form a high-viscosity starch paste-has led to its successful application in numerous fields. For instance, it serves as a sand mold binder in metal casting; is widely utilized as a sizing agent in the textile industry; acts as an additive in water-based coatings within the construction sector; and is employed in the petroleum industry to enhance the water retention and viscosity of drilling fluids. Furthermore, it serves as a raw material for subsequent modification treatments. For example, in the preparation of starch graft copolymers, pre-gelatinizing the starch feedstock prior to the grafting reaction can significantly increase the average molecular weight of the grafted side chains, while simultaneously substantially reducing the grafting frequency.
