Sodium benzoate
Benzoic acid and its salts are broad-spectrum antimicrobial agents, but their antibacterial effectiveness depends on the PH value of the food. With the increase of acidity of the medium, its bactericidal and bacteriostatic effect increased, but in alkaline medium, it lost its bactericidal and bacteriostatic effect. The optimum pH value of corrosion protection is 2.5~4.0
Application
1. Sodium benzoate is also an important preservative of acid type food. It transforms into effective form of benzoic acid during application. See benzoic acid for application range and dosage. In addition, it also can be used as fodder preservative.
2. Preservatives; antimicrobial agent.
3. Sodium benzoate agent is a very important preservative of acid type fodder. It transforms into effective form of benzoic acid during application. See benzoic acid for application range and dosage. In addition, it also can be used as food preservative.
4. Used in the research of pharmaceutical industry and plant genetic, also used as dye intermediates, fungicide and preservatives.
5. The product is used as food additive (preservative), fungicide in pharmaceutical industry, dye mordant, plasticizer inp lastic industrial, and also used as organic synthetic intermediate of spices and others.
