1, mainly used as food preservative, but also used in the production of drugs, dyes, etc
2, used in the pharmaceutical industry and plant genetic research, also used as dye intermediates, fungicides and preservatives
3. Preservative;Antimicrobial agents.
4. Sodium benzoate is also an important acid food preservative.When used, it is converted to the effective form of benzoic acid.See benzoic acid for scope and usage.In addition, it can also be used as a feed preservative.
5. The product is used as food additive (preservative), bactericide in the pharmaceutical industry, mordant in the dyestuff industry, plasticizer in the plastic industry, and also used as intermediate in organic synthesis of spices.
6. Used as a cosolvent for serum bilirubin test, food additive (preservative), bactericide in pharmaceutical industry, mordant in dyestuff industry, plasticizer in plastic industry, and also used as intermediates in organic synthesis of spices.
Sodium benzoate, also known as sodium benzoate, is a kind of organic matter, chemical formula is C7H5NaO2, is a white particle or crystal powder, odorless or microband benzoin odor, slightly sweet taste, convergence taste, relative molecular weight is 144.12, stable in the air, easily soluble in water, the pH value of its aqueous solution is 8, soluble in ethanol.
Benzoic acid and its salts are broad-spectrum antimicrobial reagents, but their antimicrobial effectiveness depends on the pH value of the food.With the increase of the acidity of the medium, its bactericidal and bacteriostatic efficacy is enhanced, but it loses its bactericidal and bacteriostatic effects in alkaline medium.Its optimal pH value for corrosion protection is 2.5~4.0.
