Sodium Carboxy Methyl Cellulose symbolized as Sodium CMC which is the sodium salt of Carboxymethyl Cellulose. It is available in a white color to cream colored powder. Sodium Carboxymethyl Cellulose is mostly used as a common form of Carboxymethyl Cellulose which is also known as cellulose gum. This chemical combination is widely used as a thickener in food production, especially in the gluten-less product. Without any doubts, this chemical combination is generally accepted as safe food additives in many countries will all authentic variables.
A Brief Note
Eatables like ice cream, mouth fresher like toothpaste, laundry detergents, and artificial teardrops, all of these counts upon synthetic gum which is Sodium Carboxymethylcellulose. This develops the creamy taste, the squeeziness, lifting strength and lubricating effect in these products. Sodium CMC is derived from natural cellulose and is treated with chloroacetic acid. Also, Sodium Carboxymethylcellulose is classified and recognized as safe for use as a food additive.
The dry form of sodium CMC is a white or slightly yellow and gray colored powder that are both odorless and tasteless. This chemically blended cellulose dissolves readily in water and is hygroscopic, which means it holds moisture in the best way. The hygroscopic properties are partly responsible for it’s functioning as a food and drug additive. Here are some of its ultimate uses that are described as—
Used as a Thickener
Sodium Carboxymethyl used to add in some products as a thickener. The best thing about it is that the amount of Sodium Carboxymethyl added can be controlled with quantity. As a thickener, sodium CMC makes easier for ingredients to get dispersed evenly throughout the mixture and also stay evenly dispersed. It helps in keeping solids suspended in liquids as keeping lotions and creams from separating.
Used as Thick Pouring Material
Adding Sodium Carboxymethylcellulose to liquids can change the viscosity of the liquid. Its molecules bind to each other where water squeezes in and breaks up the bonds. The viscosity of pouring of a liquid depends on the amount of sodium CMC added into it. Therefore, it can be used to make thick, slow-pouring gels or soothing and eye lubricants similar to natural tears.
Use as Food Additive
Sodium CMC is regularly added to foods as a stabilizer as it is commonly recognized as a safe ingredient. Further, it is also added as a bulking agent, emulsifier, firming material, gelling agent and more. It is also found in chocolate milk, cocoa, condensed milk, seasonings, soups, sauces, daily spreads, processed fruit, sausage casings, custards, dietetic foods, beer, powdered milk, cheeses and in many food ingredients.
Hence, these are some of the primary uses of sodium CMC.
