Unpopped Popcorn

Have you ever wondered why all popcorn kernels do not pop even when heated to the right temperature? Commonly known as unpopped popcorn, in this article we will try to know more about such popcorn kernels and how we can pop them.
Who doesn't love large pieces of yummy, tender popcorn especially while watching a good movie at the theater? However, while eating your way to the bottom of any bag of popcorn, you get those rock-hard, jaw-rattling unpopped kernels, known as unpopped popcorn. Quite annoying aren't they? So, let us see why some popcorn kernels resist popping into puffy white globes or what keeps these unpopped popcorn from popping.

What Makes Popcorn Pop?

We all know that every kernel of popcorn has some moisture and oil in their starchy center and it's outer shell is impervious to moisture which makes it hard. When these kernels are heated to a temperature which is more than the boiling point of water, the moisture inside the kernel turns into pressurized steam. As the hull is moisture-proof, the steam inside the kernel has no place to go, as a result the starch in the kernel gelatinizes and it becomes pliable and soft. As one continues heating, the pressure and temperature inside the hull further increase and it ruptures. Once the hull ruptures, the pressure inside the kernel drops and the steam expands, causing the starch and proteins to develop into an airy foam. The foam cools fast, and the starch and proteins turn into the crispy piece of popcorn that most of us enjoy eating. Hence, we can say that the key to a kernel explosion actually lies in the composition of its hull.

Why Popcorn Doesn't Always Pop?

As we know, it is the heat at an optimal rate that makes the popcorn pop, if the pop kernels are heated too slowly, they will remain unpopped as the steam will leak out. Besides this, kernels having excessive moisture in them do not pop well. For example, if you heat freshly harvested popcorn which is high in moisture, you might end up eating unchewy or difficult to chew popcorn. Therefore, to pop them properly, kernels need to have the right amount of moisture in them and should be heated at the right temperatures. If either of these two requirements are not satisfied, the popcorn will not pop.

How to Pop Unpopped Popcorn?

Making popcorn from unpopped kernels is easy to do and enables you to restrict the amount of fat used and adjust the flavor by adding salt, butter and other spices as per your taste. Hence, homemade popcorn is healthy and low in calorie, and also serves as the best whole grain snack that can satiate any salty craving.

Things Required
  • 2 inch deep skillet with lid
  • 1 tbsp canola oil
  • ¼ cup popcorn kernels
Directions

Put oil in the skillet and heat for a minute or so on low-medium heat. Sprinkle the kernels into the skillet and spread them evenly on the bottom of the pan in a single layer. Cover the skillet and then hold the skillet handle and lid carefully, and shake the pan to coat the kernels with oil. Allow the skillet to be on the burner and shake it after every 30 - 60 seconds. As soon as the kernels start popping, start shaking the skillet continuously. When the popping slows down, turn off the burner and remove the skillet from the burner. Once the kernels stop popping, remove the lid carefully and transfer the popcorn into a bowl for serving.
