Damage of sodium carboxymethyl methylcellulose

FAO and WHO have approved the use of pure CMC for food. It was approved after very strict molecular biology, toxicological scientific research and experiments. The national standard safe intake (ADI) is 25mg/(kg ·D), that is, about 1.5g/d per person. It has been reported that some people have an experimental intake of 15kg without toxic and side effects. CMC is not only an excellent emulsion thickener and emulsifier in food applications , And has excellent freezing and melting reliability, and can improve the taste of the product, increase the storage time. It can be trusted, so its usage will not be limited by China’s food quality standard ADI.

Incompatibility

Sodium carboxymethyl methyl cellulose is compatible with strong alkali aqueous solutions, soluble iron salts, and some other metal materials such as aluminum, mercury and zinc, etc., when PH<2, and when mixed with 95% alcohol , Will cause calmness.

Sodium carboxymethyl methyl cellulose can produce co-aggregates with pectin and gum arabic, and can also produce nitric oxide synthase with collagen, which can settle some positively charged proteins.

Processing technology

CMC is generally a cationic polymer material compound prepared by reacting pure natural methyl cellulose with caustic alkali and monochloroglacial acetic acid, with a relative molecular mass of 6400 (±1000). The key by-products are sodium oxide and sodium alcoholate. CMC belongs to pure natural methyl cellulose modified material. The United Nations Food and Agriculture Organization (FAO) and the World Health Organization (WHO) have announced that it is called “modified material methyl cellulose.”
