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 tripotassium phosphate bad for you?
Not at the small amounts used in foods—potassium phosphates are generally recognized as safe (FDA) and EFSA sets a group ADI for phosphates of 40 mg phosphorus/kg body weight/day. People with chronic kidney disease or on potassium‑restricting medications should limit phosphate/potassium additives.
What does tripotassium phosphate do to your body?
It dissociates into potassium and phosphate ions, which the body uses for electrolyte balance, energy metabolism, and bone health; the amounts from typical food uses are small. Excess intake of phosphate or potassium can be problematic for those with impaired kidney function.
How much tripotassium phosphate is in cheerios?
The manufacturer doesn’t disclose the exact amount; it’s used in small quantities as a processing aid/buffer within regulatory limits. For a precise figure, you’d need to contact the brand directly.
What is tripotassium phosphate in cheerios?
It’s E340iii, added as an acidity regulator/buffering and stabilizing agent to aid processing, control pH, and help maintain texture and mineral dispersion. It’s used in small amounts and is not a vitamin or mineral fortificant itself.
What is tripotassium phosphate in food?
Tripotassium phosphate (E340iii) is a synthetic potassium salt of phosphoric acid used as an acidity regulator, emulsifier, sequestrant, stabilizer, humectant, and thickener.
