Risks of Gluten Contamination in Popcorn

While plain popcorn kernels naturally do not contain gluten, problems arise during processing or preparation. Many store-bought popcorn products, especially flavored ones, may contain gluten containing ingredients or face cross-contamination in facilities that also handle wheat-based products.

Flavored varieties, such as kettle corn, movie theater butter popcorn, or caramel corn, may contain ingredients like wheat starch, barley malt, or other gluten-containing additives. Always read labels carefully to check for gluten free certification.

2. Movie Theater Popcorn

Movie theater popcorn can be tricky. While the kernels themselves are gluten free, the buttery flavors or seasoning powders may include gluten containing ingredients. Additionally, cross-contamination during preparation is common. If you’re unsure, ask theater staff about their popcorn’s gluten status.

3. Microwave Popcorn

Some brands of microwave popcorn contain additives or flavorings that may not be gluten free. It’s crucial to look for products labeled as certified gluten free to ensure safety.
