Why Do Some Popcorn Kernels Not Pop?

If a popcorn kernel doesn’t contain enough water, it won’t pop.

Popcorn is one of the most popular popcorn snacks. Popcorn kernels are often popped in a popcorn maker or microwaved and eaten as-is or with salt and butter. But what about popcorn kernels that don’t pop? Why does this happen, and how can we prevent it? If you’re looking for popcorn answers, keep reading!

It comes down to one simple reason: water.

Popcorn is popcorn because of the moisture content. The popcorn must be about 14% water to pop, but some kernels contain as little as 12%.

When a kernel doesn’t pop, there wasn’t enough water for the popcorn’s starch and protein coatings to expand during popping. Water-soaked popcorn becomes too moist which can also prevent the kernel from popping.

As well as the water content within your kernels, the hull can also affect whether your popcorn kernel will pop. The hull of a popcorn kernel is the crispy outside layer that encases what’s inside.

When heated, it turns into an airtight seal to help contain any water escaping from within (unless there are leaks). At 212 degrees Fahrenheit, water trapped in kernels boils and becomes steam, pushing against the tightened outer shell; as soon as pressure reaches 347 degrees F – POP!

So that’s it. For the popcorn to pop, there needs to be enough water available in a kernel’s starch and protein coatings – without it, they simply won’t expand during popping.

Why do some kernels not pop?

There are several reasons why some popcorn kernels may not pop:

  • Incorrect Moisture content: Popcorn kernels contain a small amount of water inside their hulls. If the kernel is too dry, it may not have enough moisture to create the necessary pressure buildup to pop. Conversely, if the kernel is too moist, it may not pop properly.
  • Heated to the wrong Temperature: Popcorn kernels require a specific temperature range to pop. If the temperature is too low, the kernel may not pop at all, or it may only partially pop. If the temperature is too high, the kernel may burn before it has a chance to pop.
  • Your Kernels are too old: Popcorn kernels can become stale over time, affecting their ability to pop. As kernels age, they lose moisture and become harder, making it more difficult for them to pop.
  • LowQuality Kernels: The quality of the popcorn kernel can also affect its ability to pop. Low-quality kernels may be more likely to have defects or inconsistencies that can prevent them from popping properly.
  • Bad Storage: Popcorn kernels should be stored in a cool, dry place to prevent moisture from building up inside the hull. The kernels may not pop properly if they are stored in a humid environment.

Overall, popcorn kernels that do not pop are usually due to one of these factors or a combination of them.

Remember, even under ideal conditions; there will always be a few kernels that don’t pop.
