I've been using my stash of frozen BM and each time I thaw it, it has a weird smell to it. (I thaw it under cool water, pour it in a bottle, then store it in the fridge and warm it when I'm ready to use it.) The smell isn't bad, it's just kind of odd. It's hard to explain... if I had to describe it, I'd say it kind of smells like a light, burnt plastic smell. It smells like this after I thaw it and after I warm it. When I taste it, it doesn't taste sour. It takes kinda of sweet, but weird (not sure how BM is supposed to taste though). Does this sound normal for frozen BM? My fresh BM doesn't have a smell to it.
Also, is it bad to use frozen BM that has a little bit of freezer burn?
