<<Disclaimer: Verify this information before applying it to your situation.>> I heard from a number of people. All that were using it had no ill effects and two people had checked with the manufacturer who said it was gf. I used some last night on fish and it was great. Please reply to me privately if you have successfully used it to make onion rings. Not that I need them but I haven't had any since diagnosis 2 years ago. Thanks, Barb in Springfield, Ohio, USA
