Technical Document

Sodium Benzoate Sodium benzoate is the sodium salt of benzoic acid, a highly effective preservative that inhibits yeasts, molds, and bacteria specifically in acidic foods with pH below 4.5. In the food industry, it prevents unwanted fermentation and microbial spoilage in beverages and condiments, maintains crystal-clear appearance without cloudiness or sediment, and enables safe ambient distribution of high-acid products with significantly extended shelf life while preserving fresh flavor profiles.
