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. Can dogs have rosemary extract?

    Yes—small amounts of rosemary extract (E392) used as a food preservative are generally safe for dogs; avoid giving concentrated essential oils and stop if stomach upset occurs.

  2. Can dogs eat rosemary extract?

    It’s commonly used in dog foods as a natural antioxidant and is considered safe at low levels, but consult your vet if your dog is prone to seizures or is pregnant/lactating.

  3. Can cats have rosemary extract?

    In the tiny amounts used as a preservative, rosemary extract is generally considered safe for cats; do not use rosemary essential oil, as cats are very sensitive to concentrated oils.

  4. How to extract rosemary oil?

    Rosemary essential oil is typically obtained by steam distillation of the herb, producing a highly concentrated oil that is not the same as E392 and isn’t intended for ingestion without expert guidance.

  5. How to make rosemary extract?

    Commercial E392 is made by extracting rosemary with food‑grade solvents (e.g., ethanol), then purifying and standardizing carnosic acid/carnosol levels; at home you can approximate it by steeping dried rosemary in high‑proof food‑grade alcohol and filtering, though it won’t be standardized.
