Sodium carboxymethyl cellulose is also a kind of thickener, because of its own good functional properties make it widely used in the food industry, it also promotes the rapid and healthy development of the food industry to a certain extent. For example, because it has a certain thickening emulsification effect, it can be used to stabilize yogurt drinks and increase the viscosity of the yogurt system; because it has a certain degree of hydrophilicity and hydrophilicity, it can be used to improve the quality of bread and steamed bread and other pasta, to extend the shelf life of pasta products, enhance the texture; because it has a certain degree of gelation, which is conducive to the formation of better food gel, and can be used in the manufacture of jelly and jam, etc.; it can also be used as an edible food, and can also be used as an edible food, so that the food industry can promote the rapid and healthy development to a certain extent.
