What is Sodium Benzoate?

Sodium Benzoate is a widely used food preservative. It is the sodium salt of benzoic acid, and is generally produced by reacting benzoic acid with sodium hydroxide. This compound is commonly found in processed foods and beverages due to its effectiveness in preventing spoilage from bacteria and fungi.

Sodium Benzoate is particularly valued for its ability to extend the shelf life of acidic foods such as salad dressings, carbonated drinks, jams, fruit juices, and condiments. While recognized as safe in regulated amounts, there have been debates about its safety, especially when used alongside Vitamin C, where it might form benzene, a carcinogen.

In terms of labeling, it's important to know that Sodium Benzoate is globally accepted for use in food at specified levels, though some consumer groups caution against excessive consumption due to potential health concerns.

Commonly found in: soft drinks, salad dressings, jams, fruit juices, pickles, condiments
