I have a weird question about some bagels I bought at the grocery store. They were in the refrigerator section, very cheap--5 in the package for less than $1. I knew they obviously wouldn't be as good as fresh or bakery bagels, and actually they don't taste too bad once I toast them and put a flavored spread on them.
But, my question is: They have a "sell by" date that's 3 months out... I checked the ingredients and there is calcium propionate and in parenthese it says "preservative". I know store-bought bread has preservatives in it too, but their shelf life is usually about a week.
Are these preservatives at all harmful? It would seem to me that these bagels must obviously have a much higher amount of preservatives to have that long of a shelf life, but if it's not harmful, why don't they use more of it in regular bread? We occasionally have bread that starts to go bad before we finish it, so I would think bread companies would want to extend the shelf life on the bread too...
Any food chemistry experts out there that can enlighten me?
