The role of sodium benzoate

Sodium benzoate is a very common food preservative, which has the effect of preventing deterioration and acidity and prolonging the shelf life. Sodium benzoate is more lipophilic and easily penetrates into the cell membrane, interferes with the permeability of the cell membrane, inhibits the absorption of amino acids by the cell membrane, enters the alkali storage in the ionized acidified cells of the cell, and inhibits the activity of the respiratory enzyme of the cell. The acetyl-CoA condensation reaction is prevented, thereby serving the purpose of food preservation.

Sodium benzoate is widely used in the food industry as a food preservative for the preservation of soy sauce, fruit juice, jam, etc. The pharmaceutical industry is used to prepare drugs such as sedatives such as sodium sulphate and antiseptic for medicinal syrup. It is also used for anti-corrosion and anti-mildew of anti-rust paper, latex paint, shoe polish, glue and fabric. It can also be used in the manufacture of mordants for the dye industry, plasticizers for the plastics industry and as a raw material for the perfume industry.
