Sodium acetate anhydrous E262

Sodium acetate anhydrous E262 - a preservative used as a food additive. It is a preservative that occurs naturally in food products. It has a buffering effect in the production of food products, eliminating undesirable organoleptic changes in the product. Sodium acetate is one of the few preservatives found naturally in food. Stabilization of food products consists in eliminating undesirable changes in the color, consistency and taste of food products. It has a buffering effect, maintaining a constant pH level. Sodium acetate is also used in physiotherapy as a thermal heater, a component of compresses. It is also used in cosmetics, photography and in fabric dyeing processes as a color fixative. On an industrial scale, anhydrous sodium acetate is often obtained by microbial fermentation, where the medium is, for example, sugar. The physical and chemical properties of sodium acetate are also used in chemical experiments. In school experiments, when creating aqueous solutions, there is an effective crystallization resembling the so-called. "hot ice". The crystallization of sodium acetate occurs as a result of mechanical initiation with the release of heat. This process is used in thermal warmers, compresses, hand warmers. Anhydrous sodium acetate is also used as an ingredient in the pharmaceutical industry.
