Sodium benzoate is an organic substance with a chemical formula of C7H5NaO2. It is a white granular or crystalline powder,odorless or with a slight benzoin smell, slightly sweet and astringent. Also known as sodium benzoate, the relative molecular mass is 144.12. It is stable in air and easily soluble in water. Its aqueous solution has a PH value of 8, and it is soluble in ethanol. Benzoic acid and its salts are broad-spectrum antimicrobial agents, but its antibacterial effectiveness depends on the pH of the food. As the acidity of the medium increases, its bactericidal and antibacterial effects increase, but it loses its bactericidal and antibacterial effects in alkaline media. The optimum PH value for its corrosion protection is 2.5~4.0.
Application Of Sodium Benzoate:
1.Sodium Benzoate is used in acidic foods and drinks and products to control bacteria, mold, yeasts, and other microbes as a food additive. It interferes with their ability to make energy.
2.Sodium Benzoate is used most prevalently in acidic foods such as salad dressings (vinegar), carbonated drinks (carbonic acid), jams and fruit juices (citric acid), pickles (vinegar), and condiments.
3.Sodium Benzoate can alos be used in medicine, tobacco,printing and dyeing.
