Popular questions
Is phosphoric acid bad for you?
At permitted food levels it’s considered safe (GRAS in the U.S.; EFSA sets a group ADI for phosphates of 40 mg/kg bw/day as phosphorus). Overconsumption—especially via acidic soft drinks—can contribute to dental enamel erosion, and high phosphate intakes may be a concern for people with kidney disease.
Is phosphoric acid a strong acid?
No—it's a weak, triprotic acid (pKa ≈ 2.15, 7.2, 12.3), though concentrated solutions are corrosive.
What is phosphoric acid used for?
In foods it’s used as an acidulant to add tartness and control pH (e.g., in colas) and as a sequestrant/antioxidant to stabilize color and flavor.
What does phosphoric acid do to the body?
It dissociates into phosphate ions, which are essential for bones and energy metabolism, while the acid load is buffered and excreted. High intakes from acidic drinks can erode tooth enamel, and excess phosphate may be problematic in kidney disease or with low calcium intake.
What is the formula for phosphoric acid?
H3PO4.
Is gluconic acid gluten free?
Yes. Gluconic acid (E574) is made from glucose and contains no wheat proteins, so it is gluten‑free by composition.
Can dogs have gluconic acid?
In the small amounts found in pet-safe foods or dental products, gluconic acid is generally fine for dogs; avoid giving concentrated solutions or supplements without veterinary guidance.
Is gluconic acid bad for you?
No—it's considered safe at typical food-use levels (GRAS in the U.S.; no safety concern at reported uses per EFSA), though very high amounts could cause mild stomach upset due to acidity.
Is gluconic acid safe for dogs?
Generally yes at the low levels used in foods and pet products; large or undiluted amounts may irritate the GI tract, so consult your vet before intentional supplementation.
What is gluconic acid in food?
A mild organic acid from glucose used as an acidity regulator and chelating agent, helping control pH, stabilize minerals (as gluconates), and add gentle tartness.
