Popcorn is a puffed food made of corn, ghee, and sugar that are put into a popcorn machine. It tastes sweeter.
Put an appropriate amount of corn into the popcorn pot, seal the top cover, and then turn the popcorn pot on the stove to make it evenly heated, and then pop the popcorn.
First discovered in the Inca Empire thousands of years ago, popcorn is one of the oldest snacks in the world.
Put an appropriate amount of corn (or rice) into the popcorn pot, seal the top cover, and turn the popcorn pot on the stove to make it evenly heated, and then you can pop out delicious popcorn.
This is because during the heating process, the temperature in the pot continues to rise, and the pressure of the gas in the pot also increases. When the temperature rises to a certain level, the rice grains will gradually soften, and most of the moisture in the rice grains will turn into water vapor. Due to the high temperature, the pressure of the water vapor is great, causing the softened rice grains to expand.
But at this time, the pressure inside and outside the rice grains is balanced, so the rice grains will not burst in the pot. When the pressure in the pot rises to 4-5 atmospheres, the top cover of the popcorn pot is suddenly opened, the gas in the pot expands rapidly, and the pressure decreases rapidly, making the pressure difference between the inside and outside of the rice grains larger, resulting in high-pressure water vapor in the rice grains. The rapid expansion, the instantaneous popping of rice grains, becomes popcorn.
