<<Disclaimer: Verify this information before applying it to your situation.>> I finally got a response in writing regarding Ragu Cheese Creations! The spokesperson told me on the phone and then sent out a new listing of Lipton foods that are gluten free, but the cheese sauce wasn't on the list. Guess it is too new. The only questionable ingredient was modified food starch. I received confirmation today that it is derived from corn. It does also contain soybean oil, milk and egg and annato for those who are sensitive to these things too. Just glad to finally have an easy way to make macaroni and cheese for the kids. Diane
