Sodium benzoate is used as a food additive (preservative), a fungicide in the pharmaceutical industry, a mordant in the dye industry, a plasticizer in the plastic industry, and an intermediate in organic synthesis such as spices.
Sodium benzoate is used as a preservative. Sodium benzoate is lipophilic, easy to penetrate the cell membrane into the cell body, interfere with the permeability of the cell membrane, inhibit the absorption of amino acids by the cell membrane, enter the cell body to ionize the alkali storage in the acidified cell, and inhibit the activity of the cell's respiratory enzyme system, prevent the acetyl-CoA condensation reaction, thus serving the purpose of food preservative.
