What is Sodium Benzoate?

Sodium Benzoate is a common food additive used as a preservative to prevent the growth of bacteria, yeast, and fungi in various applications. It is the sodium salt of benzoic acid, a naturally occurring compound in many fruits and spices. Sodium Benzoate is effective in acidic environments and is commonly used in acidic food and beverage products, such as soft drinks, pickles, and salad dressings, to increase their shelf life.

The manufacturing of Sodium Benzoate occurs through a chemical process that involves reacting benzoic acid with sodium hydroxide or sodium bicarbonate. The reaction results in the formation of a sodium salt of benzoic acid, which is then purified and dried into a powder form. The manufacturing process of Sodium Benzoate involves stringent quality control measures to ensure the final product is of high purity and quality.
