2.Lactic acid milk and acidic beverages
Acidic-resistant CMC can play a stabilizing role, with the characteristics of preventing precipitation and stratification, improving taste, improving quality, high-temperature resistance and so on. Good stability, not easy to precipitate; can extend the shelf life of products; strong acid resistance, PH value in the range of 2-4, can improve the taste of beverages, smooth entrance. The usage is about 4-5‰.
CMC can suspend and emulsify soymilk stably. It can prevent fat from floating and sinking, and has a good effect on whitening, sweetening and removing bean smell of soymilk. The dosage was added in the proportion of 5‰ of the total amount.

The dosage was added in the proportion of 5‰ of the total amount.
5. Bread and pasta
The application of CMC in bread production can make the bread honeycomb uniform, increase its volume, reduce slagging and not collapse, and also has the function of heat preservation and freshness preservation. CMC used in instant noodles and rolled noodles can enhance the toughness of noodles, maintain length, boil resistance, and make the taste delicate and lubricated. At the same time, when stirring and calendering, it has strong stickiness and water retention and contains water, and it is easy to stir; after steam heating, it produces a film protective layer with smooth and lustrous surface, which is easy to process; it consumes less oil in frying; it can improve the strength of the surface, and is not easy to break in packaging and handling; it has a good taste and boiling bubbles are not pasty. In addition, the application in instant noodle production can save medicinal oil, reduce costs and increase benefits. The dosage was added in the proportion of 5‰ of the total amount. It can be seen that CMC in food is widely used and has good market prospects.
