Sodium Carboxymethyl Cellulose is also a type of thickener. Due to its excellent functional properties, it has been widely used in the food industry and has contributed to the rapid and healthy development of the sector. For instance, its thickening and emulsifying effects can stabilize acid milk beverages and enhance the viscosity of yogurt systems; its hydrophilicity and rehydration properties can improve the eating quality of bread and mantou, extend the shelf life of bread products, and enhance taste; its gel-forming ability facilitates better gelation in foods, making it suitable for producing jellies and jams. Additionally, it can serve as an edible coating material, which, when combined with other thickeners, can be applied to food surfaces to maximize preservation while posing no health risks due to its edible nature. Therefore, Food grade CMC-Na, as an ideal food additive, is extensively used in food production within the food industry.
