Product features:
Sodium benzoate (chemical: C6H5CO2Na) is sodium benzoate. Sodium benzoate is an acidic antiseptic in acid environment with better antiseptic effect. It is a commonly used food preservative, which has the effect of preventing metamorphic acid and extending the shelf life.
Sodium benzoate is mostly white granule, odorless or microstrip benzoic, sweet, and astringent. Soluble in water (normal temperature) 53.0g/ 100ml, PH is around 8; Sodium benzoate is also an acidic antiseptic and has no sterilization and bacteriostasis in alkaline media. Its antisepsis optimal PH is 2.5-4.0, and the solution of 5% solution in PH5.0 is not very good. Sodium benzoate is more oil-friendly, it can penetrate cell membrane into cells, interfere with the permeability of cell membrane and inhibit the absorption of amino acids by cell membrane. In the cell, the alkali storage of ionized acid cells was entered, and the activity of the respiratory enzyme system was inhibited, and the acetyl-coa condensation reaction was prevented, thereby serving the purpose of food preservation.
