3, well, yards, ready to receive a pot of water, and then put a little bit of sugar in the water, remember, put a little bit on the line, because when the corn is cooked, itself will be out of sugar.

This is because in the heating process, the temperature inside the pot continues to rise, the pressure of the gas inside the pot is also increasing. When the temperature rises to a certain extent, the rice will gradually become soft, most of the water within the rice into water vapor. Because of the higher temperature, the pressure of water vapor is very large, so that the softened rice grain expansion. But at this time the pressure inside and outside the rice is balanced, so the rice will not burst in the pot. When the pressure inside the pot rose to 4-5 atmospheric pressure, suddenly open the top cover of the popcorn pot, the rapid expansion of the gas inside the pot, the pressure is quickly reduced, making the rice grains inside and outside the pressure difference becomes large, resulting in high pressure within the rice grains of water vapor is also rapidly expanding, instantaneous bursting of the rice grains, that is, into the popcorn.

Popcorn Contraindications and Side Effects

? Street converter-type popcorn is relatively outdated, the pot contains lead, in the high-pressure heating,

Popping a certain amount of lead in the pot will melt, and some of the lead will turn into steam and lead smoke, contaminating the ingredients. Especially in the final "burst" moment, lead is more likely to adsorb loose rice flowers. Lead is absorbed by the body, will harm the nervous, hematopoietic and digestive systems. Chronic lead poisoning is very likely to occur, and can lead to children's appetite, diarrhea, irritability, purple gums, decreased resistance, slow growth and development. In addition, some popcorn is also added a lot of saccharin, which is also not beneficial to the body. Therefore, parents do not let children often eat such popcorn.

However, this margarine brings us excess energy and trans fatty acids, extra energy will make obesity closer to us, trans fatty acids will reduce the body's high-density lipoproteins, increase low-density lipoproteins, increase the risk of cardiovascular disease, and too much intake of artificial colors may trigger the development of children with ADHD.

Of course, as long as you pay attention to the degree of control, additives can still bring us a lot of flavor and fun.

Studies have found that the chemicals in bags, including perfluorooctanoic acid (PFOA), cause infertility, liver, testicular and pancreatic cancer. Microwaves cause these chemicals to evaporate into the popcorn and thus into the body.
