Pregelatinized starch's Characteristic usage
In food applications: fast dissolution and adhesion are the main properties of pre-gelatinized starch, so it can be used in some time-critical applications, in the food industry can be used to save heat treatment and require thickening, shape protection In addition, the quality of the cake can be improved, and the internal structure of the frozen food can be stabilized. Pre-gelatinized starch is mainly used in the food industry for making soft pudding, gravy filling, pulp, dehydrated soup, seasoning agent, and marshmallows.
Application in squid culture: Usually squid feed is granular, it is composed of nutrient-rich feed powder rich in vitamins, a certain proportion of binder, oil, and so on. The binder must have the following characteristics: 1 non-toxic, Easy to digest, nutritious; 2 transparent; 3 until the squid eats, maintain the overall shape of the granules; 4 is not dissolved by the solute in the water; 5 non-stick equipment. Pre-gelatinized potato starch is the best squid feed binder, typically added in an amount of 20%.
Application in the cosmetics industry: talcum powder is a commonly used skin care product, usually made of talcum powder, starch, and other accessories. Nowadays, gelatinized starch is used in place of talcum powder and starch to make a 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.
Application in the pharmaceutical industry: The general western tablet is composed of medicinal ingredients, starch binder, lubricant, and the like. Starch mainly plays a role in material balance. The new type of tablets are made up of medicinal ingredients, pre-gelatinized lakes, and lubricants. Among them, the gelatinized starch functions as a binder in addition to the material balance. This reduces the unnecessary side effects caused by the addition of other adhesives. In addition to meeting the medical requirements, the tablets produced by this new formula also have the characteristics of high strength after molding, easy digestion after service, easy dissolution, and no toxic side effects.
In other industries: the pre-gelatinized starch is quickly dissolved in cold water to form a high-viscosity starch paste, which has been successfully used in many aspects. Such as sand-type binders in metal casting; widely used as sizing agents in the textile industry; as water-based paints in the construction industry; in the oil industry for oil well drilling, increasing water storage and viscosity; It can also be used as a raw material for further denaturation treatment. For example, in the preparation of the graft copolymer, the starch raw material is pre-gelatinized and then grafted, so that the average molecular weight of the graft-branched polymer is significantly increased, and the grafting frequency can be greatly reduced.
