Comparing E202 - Potassium sorbate vs E225 - Calcium Disulphite

Overview

E202 - Potassium sorbate

Potassium sorbate (E202) is a common preservative that helps stop yeast and mold from growing in foods and drinks. It has a neutral taste, dissolves well in water, and works best in mildly acidic foods. Most food safety agencies consider it acceptable when used as intended.

E225 - Calcium Disulphite

Calcium Disulphite (E225) is a member of the “sulfites” group used to slow spoilage and prevent browning. It acts as both a preservative and an antioxidant, but it is rarely seen on modern ingredient lists and is not widely authorised on its own in major markets. Many products instead use other sulfites like sodium or potassium metabisulphite.

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 sorbate a sulfite?

    No—potassium sorbate (E202) is a sorbate preservative, not a sulfite; E225 refers to sulfite salts such as potassium sulfite used as antioxidants/preservatives.

  2. 17. what forms when hydrochloric acid and potassium sulfite react?

    Acidifying potassium sulfite (E225) with hydrochloric acid releases sulfur dioxide (SO2) and produces potassium chloride and water.

  3. Amountof potassium sulfite to use when racking wine?

    Aim to maintain about 20–40 mg/L free SO2 (pH-dependent); winemakers usually use potassium metabisulfite, but if using potassium sulfite (E225), add an SO2‑equivalent dose to reach that target.

  4. Canon mf4350d system error e225 solution when i try to print?

    That “E225” is a printer error code and unrelated to the food additive E225, which is a sulfite preservative.

  5. E225 equals what in american money?

    E225 is a food additive code, not a currency amount, so it doesn’t convert to US dollars.
