Also known as sodium benzoate, the relative molecular mass is 144.12. It is stable in air and easily soluble in water. Its aqueous solution has a PH value of 8, and it is soluble in ethanol. Benzoic acid and its salts are broad-spectrum antimicrobial agents, but its antibacterial effectiveness depends on the pH of the food. As the acidity of the medium increases, its bactericidal and antibacterial effects increase, but it loses its bactericidal and antibacterial effects in alkaline media. The optimum PH value for its corrosion protection is 2.5~4.0.
