sodium benzoate are broad spectrum antimicrobial agents, but their antimicrobial effectiveness depends on the pH value of the food.As the acidity of the medium increases, its bactericidal and bacteriostatic effects are enhanced, but in alkaline medium bactericidal and bacteriostatic effects are lost

sodium tripolyphosphate is neutralized by phosphoric acid into sodium orthophosphate by soda ash, and then condensed. There are two methods of producing phosphoric acid, wet method and thermal method. The wet method is to react phosphate rock with inorganic acid (usually sulfuric acid, but also hydr
