Factory Supply Sodium Benzoate Preservative Food AdditivesSodium benzoate is an organic substance with a chemical formula of C7H5NaO2. It is a white granular or crystalline powder,odorless or with a slight benzoin smell, slightly sweet and astringent. 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.

Sodium Benzoate is

a white crystalline grain or powder. It is widely used for food preservative produced by reaction from sodium hydroxide with benzoic acid. Sodium Benzoate is a better molds and yeasts inhibitor and since acidity foods grow bacteria, mold and yeast quickly, it is cheapest way to preserve them.
