Popular questions
  1. Is potassium sorbate bad for you?

    Generally no; potassium sorbate (E202) is a low-toxicity preservative approved by major regulators, though high concentrations can irritate and rare sensitivities occur.

  2. Is potassium sorbate safe?

    Yes—it's considered safe at permitted food levels by authorities like FDA, EFSA, and JECFA; occasional mild sensitivities have been reported.

  3. How much potassium sorbate per gallon of mead?

    Typically about 0.6–1.0 g per US gallon (≈150–250 mg/L) to inhibit refermentation; add after fermentation is complete and alongside sulfite.

  4. How much potassium sorbate per gallon of wine?

    Commonly about 0.6–1.0 g per US gallon (≈150–250 mg/L); use with sulfite and check any local limits on sorbate levels.

  5. Is potassium sorbate gluten free?

    Yes—it's a synthetic preservative and contains no gluten, so it's suitable for people with celiac disease.

  1. Is potassium nitrate soluble in water?

    Yes—it's readily soluble in water (about 32 g per 100 g water at 20°C, increasing sharply with temperature) and only sparingly soluble in alcohol.

  2. Why is potassium nitrate classified as an electrolyte?

    Because it dissociates completely into potassium (K+) and nitrate (NO3−) ions in water, allowing the solution to conduct electricity as a strong electrolyte.

  3. How to make potassium nitrate?

    Industrial and food-grade potassium nitrate is made by neutralizing nitric acid with a potassium base (e.g., potassium hydroxide or carbonate) and then purifying/crystallizing; it should not be made at home, and food use requires regulated, food-grade material.

  4. What does potassium nitrate do for teeth?

    In desensitizing toothpastes, it helps reduce sensitivity by calming dental nerves (via potassium ions), with benefits building over several days to a few weeks of regular use.

  5. What is potassium nitrate used for?

    As E252, it's used in certain cured meats and cheeses as a preservative/curing aid under strict limits; outside food it’s used in fertilizers, some toothpastes for sensitivity, and pyrotechnics.
