Is Masa Corn Flour Gluten Free?

Yes, masa corn flour is gluten-free as it’s made from corn that has been treated with lime water (calcium hydroxide) in a process called nixtamalization. This makes it safe for people with celiac disease or gluten sensitivity, though consumers should always check specific product labels to ensure no cross-contamination occurred during manufacturing.
