Acid

Acid refers to low pH in foods and beverages. Acid ingredients (i.e., citric acid, acetic acid, fumaric acid, lactic acid, malic acid, phosphoric acid and tartaric acid) are added to foods and drinks to change pH and influence taste, prevent microbial spoilage and increase food safety by restricting bacterial growth. Acids, particularly lactic, can be naturally produced by bacterial fermentation and can act as natural preservative.
