The term hulless popcorn can often mislead consumers into thinking that they are purchasing popcorn that contains absolutely no hulls. Every popcorn kernel has a hull, known as the seed coat, which is responsible for trapping the moisture and pressure inside the kernel during the heating process, resulting in the POP. The term hulless popcorn refers to varieties of popcorn that are significantly smaller in size. During the popping process, these smaller more fragile hulls, disintegrate into tiny pieces. These pieces are small enough that they are no longer an irritation, resulting in a bowl of white, fluffy, tender hulless popcorn.
