Do all mono- and di-glycerides come from animal sources??

Question

For example the ones in Thomas bagels??? If the product is vegan is it likely that the mono&diglycerides come from a vegan source????

Thanks! : )

Answer 1

Ew, grocery store bagels.  If they're not vegan, they're disgusting.

Answer 2

As you found out, mono- and diglycerides can come from either animal or plant sources.  Sometimes contacting the manufacturer is the only way to know for sure.

If a product bears the vegan label, though, those dough conditioners would necessarily be plant-based.
