E282 - Calcium propionate
By the Daat team · Updated October 30, 2026
E282, calcium propionate, is the preservative in packaged bread.
If sliced supermarket bread does not go mouldy after two days, this is probably why. In our catalog more than half of its uses are in bread, the rest in cakes and pastries. A bakery that sells on the day it bakes usually does not need it.
In Daat’s catalog we found E282 in 129 of 16,831 products (0.8%), mostly in bread and cakes, biscuits and pastries.
