Sodium Benzoate Powder | Plant Food Preservatives

Sodium Benzoate Powder Preservatives 1 Pound Sodium benzoate has the chemical formula NaC6H5CO2; it is a widely used food preservative, with E number E211. It is the sodium salt of benzoic acid and exists in this form when dissolved in water. It can be produced by reacting sodium hydroxide with benzoic acid. The mechanism starts with the absorption of benzoic acid into the cell. If the intracellular pH changes to 5 or lower, the anaerobic fermentation of glucose through phosphofructokinase is decreased by 95%, thereby inhibiting the growth and survival of micro-organisms that cause food spoilage.
