Sodium Benzoate and Benzene As Food Preservatives
Sodium benzoate, a widely used food preservative, curbs the growth of bacteria, yeasts, and molds in products like soft drinks, sauces, and jams. Its prowess lies in pH reduction, which creates an environment hostile to microorganisms. By extending shelf life and preserving quality during storage, sodium benzoate finds its way into foods and beverages. The catch? Mixing it with ascorbic acid or citric acid can birth benzene, a potentially dangerous compound.
Concerns about the interaction of sodium benzoate with ascorbic or citric acid leading to benzene formation have spotlighted potential health impacts. Benzene, a carcinogenic compound, links to diverse cancers. Though regulated, the levels of benzene produced from the reaction are generally low. Yet, cumulative exposure from various sources matters. The risk peaks with heat or light exposure, speeding up the chemical reaction. To dodge risks, opt for products with different preservatives and storage conditions that curb benzene formation potential.
