<<Disclaimer: Verify this information before applying it to your situation.>> Greta's Sesame-Soy Marinade and her Chunky Garlic & Herb are GF. I spoke with Greta herself and she said as soon as she runs more labels they will state "gluten-free" on them. Her products are available seasonally at Costco, I'm in the NW and have found them at QFC as well. I spoke with her on the phone and she welcomes all phone calls (209) 835-7174, she is in California. Her website is http://www.gretasmarinade.com The source of the carmel color is corn syrup - she even called and verified that for me. She said she's received many calls from people who are gluten intolerant and has never had a bad report back. I have no interest in her company, they are both very tasty and I don't have the time to always whip something up from scratch. Kim Brier, Washington
