Introduction
1. Sodium Benzoate is used as a preservative in food and drinks to prevent the growth of mould, yeast and fungi. In general, salts are preferred over the acid form because they are more soluble in water.
2. Sodium benzoic is a white granule or crystalline powder with an odourless or slightly benzoin odour, a slightly sweet taste and an astringent taste. The relative molecular mass of 144.12. It is stable in air and soluble in water. Its aqueous solution has a pH of 8 and is soluble in ethanol. Benzoic acid and its salts are broad-spectrum antimicrobial agents, but their antimicrobial effectiveness depends on the pH of the food. As the acidity of the medium increases, the bactericidal and bacteriostatic effects increase, and in the alkaline medium, the bactericidal and bacteriostatic effects are lost. The optimum pH value for antiseptic is 2.5~4.0
3. Sodium benzoate is the sodium salt of benzoic acid, white granular or crystalline powder. Odorless, with a sweet astringency. E211 is a commonly used food preservative to prevent deterioration sour the effect of extending shelf life, is widely used in countries around the world
4. Sodium benzoate is primarily added to acidic foods to enhance their flavour. It can be found in pickles, sauces, jams and fruit juices. Foods that contain vinegar, such as salad dressings, typically contain very high levels of sodium benzoate. Benzene, a precursor to sodium benzoate, can be found in very small amounts naturally in some fruits, vegetables, meats, dairy products, and even drinking water.
Application
