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 for food 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.
