What is the reason why corn kernels can explode into popcorn?

Corn kernels turn into popcorn because of air pressure.

Specifically, corn seeds contain a certain amount of starch and water. When corn is heated, water begins to evaporate, and the water in starch particles is converted into steam. Since the volume of steam is much larger than that of water, the pressure of steam will gradually increase. At the same time, starch will gelatinize under the action of heat to form a gelatinous substance.

When the steam pressure reaches a certain level, the shell of corn seeds can't bear the pressure and will burst. In the process of popping, steam is released rapidly, which makes the volume of corn seeds expand rapidly, and gelatinized starch also forms fluffy structure, making popcorn soft and fluffy.

Classification of popcorn:

1, original popcorn. The original popcorn was made of corn, sugar and oil, and it tasted very sweet.

2. Chocolate popcorn. Popcorn is wrapped in chocolate. The smell of chocolate and popcorn fills your mouth and makes you want to stop.
