Properties:
Medicinesodium benzoate is white pellet mostly, nothing smelly, has tiny benzoin smell, taste is tiny sweet, sodium benzoate difficult to dissolve in water at normal temperature, tiny volatility in air (especially hot air), has hygroscopic property, dissolve in hot water, and also dissolve in ethanol, chloroform and non-volatility oil.
Sodium benzoate is also the acidity aseptic, without sterilize, restrain bacterial effect at alkalescent medium; It is antiseptic capability is the best.
Sodium benzoate easy to dissolve in oil, easy to penetrate cytomembrane enter the cellular inner, disturb the cytomembrane penetrability, restrain the cytomembrane absorb amino acid; Enter cellular inner to ionization and acidification cellular alkali reserves, restrains cellular breath enzyme system activity, prevent acetophenetidin coferment a condensation reaction, thereby to antiseptic effect of food.
Be used as food and the medicine aseptic, be used for antifreezing liquid of automobile, steel rust protection. As Food Additive be broad used for soy, vinegar, jam kind, sorbet, can etc.
