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 gluconic acid gluten free?

    Yes. Gluconic acid (E574) is made from glucose and contains no wheat proteins, so it is gluten‑free by composition.

  2. 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.

  3. 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.

  4. 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.

  5. 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.
