<<Disclaimer: Verify this information before applying it to your situation.>> I contacted Knott's Berry Farm Foods about their Season Select Strawberry Pure Preserves. The ingredients list "Natural Fruit Pectin" which could include traces of GLUTEN. The Natural Fruit Pectin is purchased from a secondary source and Knott's Berry Farm cannot be absolutely certain if GLUTEN is present. Knott's Berry Farm Salad Dressings - do contain GLUTEN. The person I spoke with was very polite and sympathetic. I thanked her and asked if she would inform the research and development people that I will share this information with the Celiac Community.
