Product Description
Sodium benzoate appears as white granules or crystal powder, odorless or slightly odorous with benzoin, slightly sweet, astringent, stable in the air, easily soluble in water, and soluble in ethanol. The advantage of sodium benzoate is that it is relatively stable in the air and has low cost. But in a sealed state. But the antibacterial effectiveness of sodium benzoate depends on the pH value of the food. As the acidity of the medium increases, its bactericidal and bacteriostatic effects increase, but in alkaline media, the bactericidal and bacteriostatic effects are lost. The optimal pH value for antisepsis is 2.5~4.0.
