I found this on the internets:
"Scanning the bags of supermarket baked goods, to my dismay I found that the vast majority of them are
not vegan as they included whey or dry milk in their ingredients. Pretty much all of them contain mono- or di-glycerides, which are most likely derived from a plant source, but if you want to be extra careful, well I can't tell you for sure.
One great way to locate vegan bread on your shelves is to look for Jewish or Kosher-friendly brands. Nearly all of these are made with no milk products whatsoever; It's against Jewish dietary law to mix milk with meat, and those manufacturer's don't want you to buy bread that you can't put pastrami on! If you like rye bread, you're in luck.
Pepperidge Farms bread is not vegan, including their burger and hot dog buns.
Thomas' English Muffins are not vegan either, though I found several vegan-friendly brands sitting right next to them on the shelf. Just about every brand and type of bagels is vegan (except egg bagels, obviously), The popular
Lender's and
Thomas New York Style brands included.
Arnold brand bread is a mixed bag. Their regular white and whole wheat pullman loaves are vegan, but most of their "Country," "Health-full," or "Grains & More" line are not, as they contain milk products. Their hamburger buns
are vegan, which is good news, as they placed second in our
hamburger bun tasting. I have a bag of their white bread and their burger buns on my shelf right now.
My beloved Martin's Potato Rolls are not vegan, unfortunately, but Arnold's potato rolls are. Other largely vegan-friendly bread brands include
Cobblestone Mill,
Dutch Country, and
Baker's Inn."
