Description

Preservative; antimicrobial agent, inhibits growth of bacteria, yeast, and molds

Risks

Notes

Sodium benzoate is created by combining benzoic acid (which naturally occurs in cranberries and other fruits) with sodium hydroxide, also known as lye. This process creates the sodium salt form of benzoic acid, which dissolves much more easily in water than plain benzoic acid. The reaction produces a white, odorless powder that's highly effective at preventing microbial growth. This preservative acts as a powerful antimicrobial agent, fighting against bacteria, yeast, and molds that would otherwise spoil your food. You'll encounter sodium benzoate in a wide variety of everyday products including soft drinks, fruit juices, salad dressings, jams, pickles, and many processed foods. It's especially popular in the beverage industry because it dissolves completely and doesn't affect taste when used in proper amounts. Sodium benzoate is synthetically produced and suitable for vegetarians, vegans, and most religious dietary requirements. It's one of the most widely used and well-studied preservatives, with regulatory approval in countries worldwide. Some individuals may be sensitive to benzoates, and like other benzoate compounds, it can potentially form benzene when combined with vitamin C under specific conditions, though food manufacturers carefully control for this.
