Chemical Properties:
  1. Primojel is white or yellow powder, odorless, tasteless, non-toxic, and easy to absorb moisture when heated. Sodium carboxymethyl starch is dissolved in water to form a colloidal solution, which is stable to light and heat. It is insoluble in organic soluble Chemicalbook agents such as ethanol, ether and chloroform. The aqueous solution of this product is relatively stable in alkali and poor in acid, generating free acid that is insoluble in water and reducing viscosity, so it is not suitable for strong acid foods. If the aqueous solution is heated above 80°C for a long time, the viscosity will decrease.
  2. Primojel white powder. Odorless and tasteless. It dissolves in water at room temperature to form a colloidal solution. It is easily soluble in water under stirring, or it can be moistened with ethanol and then added to water. Making the aqueous solution acidic will generate free acid that is insoluble in water and reduce the viscosity. Relatively stable to alkali. Adding metal salts will form various water-insoluble metal salts, so it is not suitable for strong acid foods. It is not advisable to have long-term contact with metal when making Chemicalbook. If the aqueous solution is heated above 80°C for a long time, the viscosity will decrease. The aqueous solution of this product will be partially decomposed by bacteria in the atmosphere, reducing the viscosity. It is harder to hydrolyze than ordinary starch. Insoluble in methanol, ethanol and other organic solvents. The pH of 1% aqueous solution is 6.7~7.0. The aqueous solution is more stable in alkali, but worse in acid
  1. Primojel is a modified starch etherified with carboxymethyl. It is tasteless, non-toxic, resistant to mildew, and easily soluble in water. Used in different foods, it exhibits multiple functions such as thickening, suspension, emulsification, stabilization, shape retention, film formation, expansion, preservation, acid resistance and health care. It has better performance than carboxymethyl cellulose (CMC) and replaces CMC. The best product.
  2. Food-grade carboxyl Chemicalbook sodium methyl starch is widely used in milk, beverages, frozen foods, fast food, pastries, syrups and other products. In addition, CMS is physiologically inert and has no calorific value, so it can be used to make food with low calorific value to achieve ideal results. Sodium carboxymethyl starch can be used as emulsifier, thickener, dispersant, stabilizer, sizing agent, film-forming agent, water-retaining agent, etc. It is widely used in petroleum
