East chem Pre-gelatinized starch

Superiority:

Pre-gelatinized starch is a modified starch, also known as compressible starch, which is made by partially or completely gelatinizing starch granules through physical or chemical methods. The following is the relevant introduction:

Properties

• Appearance: It is a white or off-white powder, odorless and tasteless.
• Fluidity: It has good fluidity, which enables convenient measurement and processing in industries such as pharmaceuticals and food.
• Compressibility: It has relatively good compressibility. Under the action of pressure, it can form solid tablets or other solid dosage forms, which helps to improve production efficiency and product quality.
• Solubility: It can be partially dissolved in cold water and can quickly form a uniform paste. This characteristic gives it an advantage in some applications that require rapid dissolution and thickening.

Production Process

• Usually, starch-containing raw materials such as corn, potatoes, and wheat are first screened and cleaned. Then, the starch in the raw materials is extracted through processes such as crushing and grinding to obtain crude starch. Subsequently, the crude starch is refined to remove impurities such as proteins, fats, and fibers, so as to obtain high-purity starch. The refined starch is dispersed in water to form a starch milk, and then heated to a certain temperature to make the starch granules gelatinize. During the gelatinization process, the structure of starch molecules changes, and the molecular chains gradually stretch and interweave with each other to form a viscous paste. Finally, the gelatinized starch is dried to reduce its moisture content to a certain extent, and the pre-gelatinized starch product is obtained.

Application Areas

• Pharmaceutical Industry: It is a commonly used pharmaceutical excipient, mainly used as a binder, diluent, and disintegrant for tablets. It can increase the adhesiveness of drug powders, making it easier for drugs to form tablets during the tableting process. At the same time, after the tablets enter the human body, they can disintegrate rapidly, release the drug components, and improve the dissolution rate and bioavailability of the drug.
• Food Industry: It can be used as a thickener, stabilizer, emulsifier, etc. in various foods. In baked foods, it can improve the processing performance of the dough, increase the toughness and extensibility of the dough, and make the baked products softer and larger in volume. In dairy products, it can prevent the separation of whey and improve the stability and taste of the products. In meat products, it helps to retain moisture, increasing the tenderness and elasticity of the products.
• Other Industries: In cosmetics, it can be used to adjust the texture and consistency of products, making cosmetics have better spreadability and stability. In the paper industry, it can improve the strength and surface smoothness of paper. In the textile industry, as a sizing agent, it can improve the abrasion resistance and weavability of yarns.
