Sodium acetate: (i) sodium acetate, (ii) sodium diacetate (E262) – what is it?
Sodium acetate is the sodium salt of acetic acid. Sodium diacetate, also designated as E262, is its organic ester. Both substances are commonly used as food additives with a variety of applications.
Properties of sodium acetate
Sodium acetate comes in the form of a white, crystalline powder with a characteristic acetic acid smell. It is easily soluble in water and alcohol, making it convenient for use in the food industry. Sodium diacetate, on the other hand, has similar physical and chemical properties.
Uses of sodium acetate
Sodium acetate is widely used as a preservative, acidity regulator and flavoring agent in the food industry. It is also used in the production of vinyl acetate, cellulose acetate and other organic chemicals. Sodium diacetate is often used as an anti-clumping agent for powdered products such as spices, flour and baking powder.
Where to buy sodium acetate?
Sodium acetate and sodium diacetate are available in chemical stores and some grocery stores. They can be sold both as pure substances and as ingredients in finished food products.
Sodium acetate and its functions in food
Sodium acetate has many functions in the food industry. As a preservative, it helps extend the shelf life of food products by preventing the growth of microorganisms such as bacteria and mold. In addition, as an acidity regulator, it can be used to regulate the pH of various products, which affects their taste, texture and shelf life. Sodium diacetate, on the other hand, prevents loose substances from sticking together, making them easier to package, store and use by consumers.
