Popcorn without hulls has minimal seed coats. All popcorn has a hull. The popcorn we consider hulless are very small in size. Once the popcorn pops, most of the hull disintegrates, leaving a tender kernel. Avoid using hulless popcorn in air poppers. Small popped popcorn is tender and packed with antioxidants and fiber. This whole grain food is GMO-free and not suitable for air poppers.
