Corn Starch CAS NO.9005-25-8

Corn starch is a type of starch extracted from corn and it is a polysaccharide carbohydrate. The following is a detailed introduction and its applications:

Basic Information

• Appearance: Usually a white powder with a slight pale yellow tint, and it has a fine texture.
• Composition: It is mainly composed of glucose molecules polymerized together, and contains a small amount of impurities such as proteins, fats, and ash.
• Properties: It is odorless and tasteless,In hot water, it can gelatinize to form a transparent paste with a certain viscosity. Its gelatinization temperature is generally between 62℃ and 72℃.

Applications

• Food Industry
  • Thickening Agent: It is used in the production of various soups, sauces, puddings, jellies and other foods to give them an appropriate consistency and texture. For example, when thickening a dish, mixing corn starch with water to make a starch solution and pouring it into the pot can thicken the soup, enhancing the color and taste of the dish.
  • Leavening Agent: In baked goods such as cakes and breads, when used in combination with leavening agents like baking powder, it can make the products more fluffy and soft. Corn starch can absorb excess water, helping to maintain the moisture and structure of the dough or batter.
  • Sugar Coating and Candy Making: It is used to make the sugar coating of candies, making the surface of the candies smooth and glossy, and also preventing the candies from sticking to each other. In the production of some hard candies, soft candies and chewing gums, corn starch also plays an important role, such as adjusting the texture and taste of the candies.
  • Preservative: It can be one of the components of food preservatives, used to extend the shelf life of food. For example, in the preservation treatment of some fruits and vegetables, using a preservative containing corn starch can form a protective film on their surface, reducing water evaporation and oxidation.
• Pharmaceutical Industry
  • Tablet Excipient: It is one of the commonly used auxiliary materials for making tablets, and can be used as a diluent, binder and disintegrant. It can increase the volume and weight of the tablets, enabling the drug powder to be compressed into shape. At the same time, in the human gastrointestinal tract, it can help the tablets to disintegrate quickly and release the drug ingredients.
  • Capsule Filler: It is used to fill capsules. Mixing the drug powder with an appropriate amount of corn starch and then filling it into the capsule shells helps with the storage and administration of the drug, ensuring the release and absorption of the drug in the body.
• Industrial Field
  • Paper Industry: It is used for the surface sizing and internal addition of paper. Surface sizing can improve the surface strength, smoothness and water resistance of the paper, reducing the phenomena of powdering and fluffing during the printing and writing processes of the paper; internal addition can increase the stiffness and flexibility of the paper.
  • Textile Industry: As one of the main components of textile sizing agents, it is used for the sizing treatment of yarns. It can improve the strength, abrasion resistance and smoothness of the yarns, reducing the breakage rate of the yarns during the weaving process and improving the quality of the fabrics.
  • Adhesive Production: In the formula of some adhesives, corn starch can be used as a thickening agent and stabilizer to improve the performance of the adhesives, making them have better adhesion and stability.
  • Biodegradable Materials: It can be used as one of the raw materials for the production of biodegradable plastics. When mixed with other polymer materials, it can improve the biodegradability of the plastics and reduce environmental pollution.
