Popular questions
Is calcium propionate bad for you?
No—at permitted food levels, calcium propionate (E282) is considered safe by regulators (FDA GRAS; EU-approved) and is rapidly metabolized. A small number of people may be sensitive, but evidence of harm at typical dietary exposures is limited.
What is calcium propionate made from?
It’s the calcium salt of propionic acid, usually produced by neutralizing propionic acid with calcium hydroxide or calcium carbonate. The propionic acid can come from petrochemical synthesis or fermentation by Propionibacterium.
Is calcium propionate banned in europe?
No—E282 is authorized in the EU as a preservative in specified foods under Regulation (EC) No 1333/2008, with set maximum levels. It is not permitted in foods for infants and young children.
What is calcium propionate used for?
It’s a preservative that inhibits molds and some bacteria to extend shelf life. In baking, it helps prevent mold and “rope” spoilage in bread and similar products.
What is calcium propionate used in?
Commonly in bread, rolls, tortillas, cakes, and other baked goods; it’s also permitted in some processed cheeses depending on the jurisdiction. Specific uses and limits vary by country and product category.
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.
