Phosphoric acid (H₃PO₄) is an inorganic mineral acid that occurs as a transparent, colorless, and viscous liquid.

Phosphoric acid (E338) is a fundamental additive in the food industry, valued for its powerful acidifying and pH-regulating capacity, especially in carbonated beverages, which provides precise control of acidity without altering the flavor or color profile of the products.

In this way, phosphoric acid is an essential tool for manufacturers seeking to optimize the quality, stability, and appeal of a wide range of food products.

Regulatory Status and Safety Considerations

Phosphoric acid is a widely studied food additive and is considered safe for human consumption at the doses permitted by major regulatory authorities, including:

U.S. Food and Drug Administration (FDA): Classifies it as a “generally recognized as safe” (GRAS) food ingredient for use as an acidulant and pH regulator.
European Food Safety Authority (EFSA): Classified as a food additive (E338) and considered safe, with maximum use limits established in various food categories.
Joint FAO/WHO Expert Committee on Food Additives (JECFA): Has established an acceptable daily intake (ADI) for phosphates (expressed as phosphorus) of 70 mg/kg of body weight.
