Dehydroacetic acid is E265; decanal is a flavoring and does not have an E‑number.
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.
