<<Disclaimer: Verify this information before applying it to your situation.>> I recently purchased some salad dressing at the health food store that appears GF (rice vinegar, etc.) BUT it contains keltrol - a natural emulsifier. Does anyone have a clue what this might be? If it's natural, I assume it must be some form of plant or animal life, so it might be GF, but I have allergies to numerous other things. Jennifer Duke
