In the modern food industry, food additives play a crucial role. They not only improve the quality, taste, and appearance of food but also extend its shelf life and ensure food safety and hygiene. Among the many food additives, food-grade sodium carboxymethyl starch, with its unique properties and wide range of applications, has become an indispensable part of the food industry.

　　Food-grade sodium carboxymethyl starch, also known as sodium carboxymethyl starch or CMS-Na, is a white or off-white powder obtained by chemically modifying natural starch. This substance dissolves rapidly in water to form a clear, viscous solution and has good stability and adhesion. Due to its non-toxic, tasteless, and odorless properties, as well as its excellent thickening, stabilizing, and emulsifying performance, food-grade sodium carboxymethyl starch is widely used in various foods.

　　In the dairy industry, food-grade sodium carboxymethyl starch can be used as a stabilizer and thickener to improve the taste and texture of products such as yogurt and milkshakes. By increasing the viscosity of food, it makes dairy products smoother and more refined, enhancing the consumer experience. At the same time, it can also help dairy products maintain a stable form and prevent layering and sedimentation.

　　In baked goods, food-grade sodium carboxymethyl starch also plays an important role. As an improver for bread, cakes, and other baked goods, it improves the dough's gas retention and elasticity, making the baked goods softer and tastier. In addition, it can also help food retain moisture and extend its shelf life.

　　In addition to dairy products and baked goods, food-grade sodium carboxymethyl starch is also widely used in beverages, jams, condiments, and other foods. In beverages, it can be used as a suspending agent and stabilizer to prevent the sedimentation of particulate matter; in jams, it can increase the viscosity and gloss of the jam, making it more attractive; in condiments, it can be used as a thickener and carrier to improve the stability and solubility of the condiments.

　　It is worth noting that although food-grade sodium carboxymethyl starch plays an important role in the food industry, its usage and application range are strictly regulated. Before use, food producers need to ensure that it meets relevant standards and regulations to ensure food safety and compliance.
