Detailed explanation-1: -Benzoic acid (BA) is a commonly used antimicrobial preservative in food and beverages, especially in carbonated beverages, as it presents its strongest antibacterial activity at pH 2.5–4.0. BA has inhibitory effects on the proliferation of bacteria and yeasts, a major cause of food spoilage.
Detailed explanation-2: -Benzoic Acid is a white, crystalline (sand-like) powder with a faint, pleasant odor. It is used to make other chemicals, in perfumes and flavorings, and as a food preservative and anti-fungal agent.
Detailed explanation-3: -The six major additives (Figure 1) consist of three artificial sweeteners (saccharin, aspartame, acesulfame K), a stimulant (caffeine) and two preservatives (sorbate, benzoate).
Detailed explanation-4: -Benzoic acid and sorbic acid are widely used for food preservation. These preservatives are generally recognised as safe. The aim of this study was to determine the level of benzoic and sorbic acid in food samples that are usually consumed in Iran.
