<<Disclaimer: Verify this information before applying it to your situation.>> Couldn't find a reference to Knorr's on this list, so searched and found the following from the Best Foods home page -- Knorr's section: (I was looking for Chicken Soup base by Knorr's since their label gives no indication that it contains anything containing gluten. I sent an email to their Lebanon plant (Middle East) but never got any reply.I have had no reaction from it.) "Most Knorr products are made with gluten-containing ingredients, and cannot be considered gluten free. Common ingredients that may contain gluten are rye, wheat, oats and barley, and noodles or pasta prepared with any of the previously mentioned grains. HVP and TVP, are likely to contribute gluten as well. They are always listed in the ingredient statement. Because product formulations may change we recommend that you always read individual labels carefully to guide your choice of foods that fit your dietary needs."
