Spices And Sodium Benzoate

Spices are a diverse group of dried plant parts, such as seeds, fruits, roots, bark, or buds, used in small amounts for flavoring, coloring, or preserving food. Sodium benzoate is a salt of benzoic acid, a synthetic compound that occurs naturally in some plants. It is produced industrially by reacting toluene with chlorine and then oxidizing the resulting benzyl chloride.

Spices are used to add flavor and aroma to a wide variety of foods, from savory dishes to baked goods. Sodium benzoate is primarily used as a preservative to inhibit the growth of mold, yeast, and bacteria, extending the shelf life of products like sauces, soft drinks, jams, and pickles.

The FDA lists spices as Generally Recognized As Safe (GRAS) when used for flavoring. Sodium benzoate is also approved by the FDA as a food preservative. When used within permitted levels, it is generally considered safe. However, when sodium benzoate reacts with ascorbic acid (vitamin C) in some beverages, it can form small amounts of benzene, a known carcinogen. Regulatory bodies like JECFA and EFSA have evaluated sodium benzoate and set acceptable daily intakes. Research into potential links between sodium benzoate and hyperactivity in children has yielded mixed results.
