Nature

Usually, its sodium salt, also known as CMS-Na, is used. Its shape is white or yellow powder, odorless, odorless, non-toxic, and easily hygroscopic when heated. Dissolve in water to form a colloidal solution, which is stable to light and heat. Insoluble in organic solvents such as ethanol, ether, chloroform, etc. The aqueous solution of this product is relatively stable in alkali, but poor in acid, generating insoluble free acids and reducing viscosity. Therefore, it is not suitable for strongly acidic foods. If the aqueous solution is heated above 80 ℃ for a long time, the viscosity will decrease. This product has similar properties to carboxymethyl cellulose (CMC), with various properties such as thickening, suspension, dispersion, emulsification, bonding, water retention, and protective colloid. It can be used as an emulsifier, thickener, dispersant, stabilizer, sizing agent, film forming agent, water retaining agent, etc. It is widely used in industrial sectors such as petroleum, textile, daily chemical, cigarette, papermaking, construction, food, medicine, etc., and is known as “industrial monosodium glutamate”. It is an alternative product to CMC. It can replace polyvinyl alcohol in certain fields. Unlike CMC, the aqueous solution of this product is partially decomposed by bacteria in the air (resulting in α- Amylase is prone to liquefaction, causing a decrease in viscosity. Therefore, the prepared aqueous solution is not easy to store for a long time and is not easy to use for seasoning tomato sauce, etc. Dissolution method: According to the required concentration, add water in proportion to the product and stir thoroughly to completely dissolve it. Alternatively, wetting with a small amount of ethanol before dissolving with water is more effective.
