Popular questions
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.
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.
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.
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.
Is potassium sorbate gluten free?
Yes—it's a synthetic preservative and contains no gluten, so it's suitable for people with celiac disease.
Is sodium bisulfite bad for you?
At approved food-use levels, sodium bisulfite (E222) is considered safe; regulators set a group ADI of 0–0.7 mg/kg body weight expressed as SO2. However, sulfite‑sensitive people—especially some asthmatics—may experience reactions like wheezing, hives, or headaches and should avoid it.
What is sodium bisulfite used for?
It’s an antioxidant and preservative that prevents browning and oxidation and helps control microbes, commonly used in products like wines, dried fruits, shrimp, and cut potatoes.
What is sodium bisulfite in food?
It’s a sulfiting agent (E222) that releases sulfur dioxide to protect color and flavor and extend shelf life; it must be declared on labels when present above about 10 ppm (as SO2).
How much sodium bisulfite to neutralize chlorine?
Approximately 1.5 mg of sodium bisulfite (NaHSO3) is needed per 1 mg of free chlorine (as Cl2) per liter, stoichiometrically. In practice use a slight excess and confirm with a chlorine test; the reaction releases heat and SO2, so handle carefully.
Is sodium bisulfite gluten free?
Yes—sodium bisulfite is a synthetic mineral salt and contains no gluten; any gluten risk would come from other ingredients, not the additive itself.
