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.
Where does propionic acid come from?
It occurs naturally, produced by Propionibacterium in fermented foods (like Swiss-type cheeses) and in the human gut, and is also made commercially by microbial fermentation or petrochemical synthesis.
Is propionic acid a strong acid?
No—it's a weak carboxylic acid (pKa about 4.9), similar in strength to acetic acid.
What is propionic acid used for?
As a food additive (E280), it acts as a preservative that inhibits mold and some bacteria, commonly used in bread, baked goods, and cheese; its salts (e.g., calcium or sodium propionate) are also used.
How is propionic acid made?
It’s produced industrially via petrochemical routes (e.g., hydroformylation/oxidation of ethylene or hydrocarboxylation) and by fermentation using Propionibacterium on sugars or glycerol.
How to reset a sansa e280?
This question is unrelated to the food additive E280 (propionic acid); for resetting a Sansa e280 media player, please consult the device manual or the manufacturer’s support site.
