East chem Corn Starch

Superiority:

Corn starch, also known as maize starch, is a type of starch extracted from corn and is widely used in various fields such as food, industry, and medicine. The following is the relevant introduction:

Properties

• Appearance: It is a powder with a slight pale yellowish tint on a white background.
• Odor: It has the unique odor of corn starch and no peculiar smell.
• Solubility: It is insoluble in cold water. When in hot water, it will undergo gelatinization to form a paste with a certain viscosity.
• Chemical Properties: It is composed of many glucose molecules polymerized together and belongs to polysaccharides. Under the action of acids or enzymes, it can be gradually hydrolyzed to produce maltose, glucose, etc.

Production Process

• Corn Cleaning: Remove impurities in corn, such as stones, metals, dust, etc., to ensure the product quality.
• Soaking: Soak the corn in an aqueous solution containing sulfurous acid to soften the corn, making it easier for subsequent grinding and starch separation.
• Grinding and Crushing: Crush the corn through grinding equipment to separate the starch granules from other components.
• Starch Separation: Use methods such as centrifugal separation and filtration to separate the starch from the corn slurry to obtain crude starch milk.
• Purification: Further purify the crude starch milk to remove impurities such as proteins, fats, and fibers, and improve the purity of the starch.
• Drying: Dry the purified starch milk to obtain the finished corn starch product.

Applications

• Food Industry: It is a commonly used thickener, stabilizer, and filler in the food industry. It is used to make various pastries, biscuits, bread, etc., which can make the products have a delicate taste and a soft texture. When added to sauces and soups, it can increase the consistency. It can also be used in meat processing to keep the meat moist and tender.
• Industrial Field: In the paper industry, it is used for the surface sizing and internal addition of paper, which can improve the strength and gloss of the paper. In the textile industry, as a sizing agent, it can make the yarn surface smooth and reduce the breakage rate. It is also an important raw material for producing chemical products such as glucose, alcohol, and citric acid.
• Medical Field: It can be used as an excipient for drugs to help form tablets, capsules, etc. In some topical medications, it can also play the roles of moisture absorption and heat dissipation.

Storage Method

• It should be stored in a cool, dry, and well-ventilated warehouse, avoiding direct sunlight and a humid environment to prevent the starch from getting damp, caking, and becoming moldy.
• It should be stored separately from items with strong odors because corn starch easily absorbs odors, which will affect its quality.
• The storage temperature is generally preferably controlled at 10 - 25°C, and the humidity is around 60% - 70%. At the same time, pay attention to regularly checking the inventory to prevent pests and rodents.
