Is there gluten in deep frying oil?

Deep frying oil itself does not contain gluten, as gluten is a protein found in certain grains like wheat, barley, and rye. However, if the oil has been used to fry gluten-containing foods, it may become contaminated with gluten particles. Therefore, for those with gluten sensitivities or celiac disease, it's important to ensure that the oil is dedicated to frying gluten-free items to avoid cross-contamination.
