Popular questions
  1. Is citric acid bad for you?

    At typical food levels, citric acid (E330) is considered safe by major regulators (GRAS; EFSA/JECFA). Concentrated or frequent acidic exposure can irritate the mouth/stomach or contribute to tooth enamel erosion.

  2. Where does the citric acid cycle occur?

    In eukaryotic cells it occurs in the mitochondrial matrix; in bacteria it occurs in the cytosol.

  3. What does citric acid do to your body?

    It is a normal intermediate in energy metabolism and is readily metabolized to carbon dioxide and water. Citrate can bind minerals, which may enhance absorption of some and help prevent certain kidney stones by increasing urinary citrate.

  4. Where does citric acid come from?

    It occurs naturally in citrus fruits, but most food-grade citric acid is produced by fermenting sugars (e.g., from corn, beet, or cane) with Aspergillus niger.

  5. How is citric acid made?

    Industrially, sugars are fermented with Aspergillus niger to produce citric acid, then it is recovered and purified—often by precipitating calcium citrate and converting it back with sulfuric acid or via ion-exchange/crystallization.

  1. 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.

  2. Is malic acid gluten free?

    Yes. Malic acid is inherently gluten-free; check the overall product for other gluten-containing ingredients.

  3. 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.

  4. 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.

  5. 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.
