Popcorn without a hull means less of a seed coat. All popcorn has a hull. The varieties we consider hulless are very tiny in size. When popped, most of the hull disintegrates, leaving a small tender kernel. Hulless popcorn is not suitable for air poppers. Small popcorn, when popped, is tender, rich in antioxidants, and high in fiber. This GMO free whole grain food is not recommended for air poppers.
