What principle does popcorn use?

Popcorn uses the principle of air pressure.

In the process of making popcorn, corn kernels are first put into a sealed container, and then the container is heated to raise the temperature in the container. With the increase of temperature, the air pressure in the container will gradually increase, and the pressure inside the corn kernels will also increase. When the temperature reaches a certain level, the pressure inside the corn grain will exceed its bearing capacity, which will lead to the explosion of the corn grain.

During the explosion, the outer layer of corn grains will expand outward to form a fluffy structure, while the inner layer will be compressed into a sponge-like structure. This structure makes popcorn crisp in taste and unique in flavor, making it one of people's favorite snacks.

Matters needing attention in making popcorn

1, choose the right corn kernels: the corn kernels for making popcorn usually choose special popcorn kernels, which are more suitable for explosion and taste better.

2. Choose the right pot: the pot for making popcorn should be deep and wide enough to hold enough corn kernels, and at the same time, it should ensure that the pot has enough tightness and can generate enough pressure when heated.

3. Control the temperature and time: If the temperature is too high or the heating time is too long, popcorn may be burnt or harmful substances may be produced, so control the temperature and time. Generally speaking, popcorn will explode when heated to a certain temperature, so turn off the heating in time.
