Is Soybean Flour Gluten Free?

Yes, soybean flour is naturally gluten-free as it’s made from ground soybeans which do not contain the proteins found in wheat, barley, or rye. However, those with celiac disease or gluten sensitivity should check product labels to ensure the soybean flour hasn’t been processed in facilities that also handle gluten-containing grains, which could lead to cross-contamination.
