The principle of making popcorn is the principle of using air pressure.

When popcorn is processed, the corn (multi-grains can be used) is heated in a special container, so that the corn is in a state of high temperature and high pressure, the temperature in the pot keeps rising, and the gas pressure in the pot keeps increasing.

Then, with a bang, the cover of the machine was opened and the corn was suddenly released at normal temperature and pressure. The gas in the pot expands rapidly and the pressure drops rapidly, which increases the pressure difference between the inside and outside of corn kernels, which leads to the rapid expansion of high-pressure steam in corn kernels, which instantly explodes corn kernels into popcorn, and at the same time, the internal structure and properties of corn change. Most popcorn is basically popcorn popped by simply heating popcorn.

Extended data

When popcorn is processed, in order to make the taste of popcorn more attractive, a lot of margarine will be added, and some popcorn flavors will be added; In order to make the popcorn more beautiful, some pigments were added. He was wearing a beautiful coat.

However, this margarine brings us extra energy and trans fatty acids. Extra energy will bring obesity closer to us. Trans fatty acids can reduce high density lipoprotein, increase low density lipoprotein, and increase the risk of cardiovascular and cerebrovascular diseases. Excessive intake of artificial pigments may lead to ADHD in children.

With the progress of science and technology, the popcorn machine has also been greatly improved. Stainless steel popcorn machine gradually replaced the former converter machine; The popular aluminum popcorn machine in previous years was gradually replaced by stainless steel popcorn machine with people's understanding of the harm of aluminum tableware, and the pollution in production gradually disappeared.

Many high-grade popcorn are made of non-trans fats such as coconut oil and palm oil, and corn itself is nutritious, which can make popcorn delicious and nutritious, so it can also be very healthy!
