Does vanillin contain gluten? My mother made gluten free choc chip cookies for my son and she called the manufacturer and they said that they were gluten free and casein free. No wheat or milk derivatives.
But they contain vanillin and I thought that was an “unacceptable”, so what do you think?
I found some answer for my question in a forum that said pure vanillin should be gluten free, but if the vanillin is in an alcohol solution there are chances that it is a grain alcohol which is not gluten free. The chances may be slim but it is best to contact the manufacturer.
