Popular questions
Is malic acid bad for you?
No—at normal food levels it’s considered safe (GRAS in the U.S. and authorized in the EU); very high intakes or very sour products can irritate the mouth or stomach.
Is malic acid gluten free?
Yes. Malic acid is inherently gluten-free; check the overall product for other gluten-containing ingredients.
What is malic acid used for?
It’s an acidulant that provides a tart, apple-like sourness and adjusts pH in foods and drinks, commonly in beverages, candies, and fruit preparations.
Is malic acid bad for your teeth?
Acids like malic acid can contribute to enamel erosion with frequent exposure (e.g., sour candies, acidic drinks); limiting contact time and rinsing with water can help.
Is malic acid vegan?
Yes—malic acid is typically vegan, made synthetically or by microbial fermentation without animal-derived inputs, though other ingredients in a product may not be.
Is formic acid a strong acid?
No—formic acid is a weak acid in water (pKa ≈ 3.75), though concentrated solutions are corrosive.
What is formic acid used for?
As E236, it’s used mainly as an antimicrobial preservative and acidity regulator (especially in animal feed and silage), and outside food in leather/textile processing, rubber coagulation, beekeeping, and as a chemical intermediate.
What does formic acid smell like?
It has a sharp, pungent, vinegar-like odor that’s acrid and stingy (reminiscent of ant stings).
What does formic acid do to the body?
At low food-use levels it’s metabolized to formate and then to carbon dioxide, but concentrated exposure irritates and can burn skin, eyes, and airways; large ingestions may cause metabolic acidosis and systemic toxicity.
Does formic acid have hydrogen bonding?
Yes—its carboxyl group donates and accepts hydrogen bonds, often forming dimers, which contributes to its relatively high boiling point.
