Sodium benzoate is a broad-spectrum antimicrobial agent, but its antimicrobial effectiveness is dependent on the pH of the food. As the acidity of the medium increases, its bactericidal and bacteriostatic effects are enhanced, but in alkaline medium, the bactericidal and bacteriostatic effects are lost. The optimum pH value of its anticorrosion is 2.5~4.0.
