<<Disclaimer: Verify this information before applying it to your situation.>> Hello List: I checked the archives & didn't quite find a complete answer on what sources of foods can be used to create edible-grade glycerin found in foods (a sweetener). I understand glycerin can be vegetable based or from coconut oils. What other sources are used? I'm inquiring since my child's vitamin drops contain glycerin. When I called Morton Pharmaceuticals, IL, the technologist stated that sometimes glycerin can cause adverse reactions to some people, but that it doesn't come from wheat, etc. He sounded a bit uncertain. Thanks for any input. Wendy, PA [log in to unmask]
