1, in the food application: fast dissolution and adhesion is the main property of pre-gelatinized starch, so it can be used for some of the more stringent time requirements of the occasion, in the food industry can be used to save the heat treatment and require thickening, preservation of the type and so on, can improve the quality of pastries, stabilize the internal structure of the frozen food organization and so on. Pregelatinized starch is mainly used in the food industry to make soft pudding, gravy filling, paste, dehydrated soup, seasoning agent and juice soft candy.
2, in eel farming is the application: usually eel feed for granular, it is rich in vitamins and other nutrients from the feed powder, a certain proportion of the binder, grease, etc., which must have the following characteristics of the binder: non-toxic, easy to digest, nutritious; transparent; until the eel eaten before the end of the particles have been maintained in the overall shape of the particles; not be dissolved by the solutes in the water; do not stick to the equipment. Pregelatinized potato starch is the best eel feed binder, and is usually added at 20%.
3, in the cosmetics industry: talcum powder is a commonly used skin care products, generally made of talcum powder, starch and other auxiliary materials. In recent years, foreign countries use dextrinized starch to replace talc and starch to make new type of talcum powder, in addition to the characteristics of ordinary talcum powder, it also has the characteristics of good skin affinity and strong water absorption.
4, the application of the pharmaceutical industry: general western medicine tablets are composed of medicinal ingredients, starch bonding agent, lubricants and so on. The starch mainly plays the role of material balance. New tablets are made of medicinal ingredients, pre-gelatinized starch and lubricants. The dextrinized starch in them plays the role of a binder in addition to the role of material balance. This reduces unwanted side effects caused by the addition of other binders. As a result of this new formula produced by the tablets in addition to meet the medical requirements, but also has a high strength after molding, easy to digest after serving, easy to dissolve and no toxic side effects and other characteristics.
5, in other industries on the application: pre-gelatinized starch quickly dissolved in cold water and the formation of high-viscosity starch paste characteristics in many aspects of its successful application. Such as in the metal casting for sand binder; in the textile industry is widely used as sizing agent; in the construction industry as water quality coatings, etc.; in addition can also be used as a raw material for further denaturation treatment. Such as in the preparation of starch graft **** polymer, starch raw materials are first pre-pasteurized and then grafting reaction can make the average molecular weight of the grafted branched polymer increased significantly, while the grafting frequency can be greatly reduced.
6, pre-gelatinized starch, also known as pre-gelatinized starch, α-starch, is a simple processing, widely used modified starch. The definition of starch in the International Organization of Standards says that pre-gelatinized starch is "a modified starch obtained by drying starch paste (with or without the addition of chemical reagents), cold water contact or make its gelatinous dispersion, with obvious swelling characteristics.
