Why it's used
In foods, phosphoric acid is primarily used as an acidulant to provide a tart or sour flavor, especially in soft drinks. It also acts as a preservative by lowering pH, which can inhibit the growth of bacteria and molds. It is commonly found in sodas, processed cheeses, and some baked goods.
Health notes
Phosphoric acid is generally recognized as safe (GRAS) by the FDA for use as a food additive. JECFA has evaluated phosphoric acid and related phosphates and set an acceptable daily intake. EFSA has also evaluated phosphoric acid and concluded it is safe at current use levels. Some studies suggest that very high intake, particularly from soft drinks, may be linked to concerns regarding bone health and dental erosion, though evidence is mixed and often related to overall dietary patterns rather than phosphoric acid alone.
