1, the harm of eating popcorn
Most street stalls in China use cast iron popcorn for machining, and the produced fake popcorn has certain security risks.
When the popcorn machine is heated, it must be sealed to generate high air pressure inside. When the popcorn machine is heated, some lead in the popcorn machine will overflow in the form of lead vapor and lead smoke, which will directly pollute the food. When the pressure is rapidly reduced, lead is more easily absorbed by loose popcorn.
If this lead enters the human body with popcorn, it will damage the nervous system and digestive system. In particular, children's detoxification of lead is weak, and eating popcorn with high lead content is prone to chronic lead poisoning, resulting in loss of appetite, diarrhea, irritability, purple gums and slow growth and development.
2. Beware of popcorn that tastes too fragrant
When some street vendors fry popcorn with aluminum pot to save money, they will use vegetable cream made of hydrogenated vegetable oil instead of butter, and add various flavors and pigments.
When popcorn is heated in a microwave oven, the fragrance emitted contains a substance called diacetyl. A small amount of this substance is not harmful to human body, but if it is often exposed to too much of this substance, it will definitely bring health hazards to human body.
Experts remind consumers that when using microwave oven to heat popcorn at home, they should stay away from the heating area for at least two meters. After heating, it is best to open the packaging bag and put it in a ventilated place to give off the smell before eating.
When processing popcorn, some vendors will add a lot of margarine to make it sweeter. Director Ju Juan said that the trouble with margarine is that it contains trans fatty acids, which can easily lead to obesity and endanger cardiovascular and cerebrovascular health.
2. Tips for choosing popcorn
The selection of popcorn can be made from the following aspects: the high-quality popcorn is full of granules and tastes sweet, and its quality is largely influenced by the ingredients such as butter, while the inferior popcorn is uneven in sweetness and thin in granules, and the taste is greatly discounted because of the stingy use of ingredients during production. As can be seen from the color, the high-quality popcorn has a faint champagne color of butter, while the inferior popcorn is white.
3. Reminder of eating popcorn
Street-style converter-type explosion pot is relatively backward, and the pot contains lead. When heated at high pressure, a certain amount of lead in the popcorn explosion pot will melt, and some lead will become steam and lead smoke, which will pollute the raw materials. Especially at the last moment of "explosion", lead is more easily adsorbed on loose rice flowers. When lead is absorbed by human body, it will harm nervous system, hematopoietic system and digestive system. Chronic lead poisoning is easy to occur, and it can lead to children's loss of appetite, diarrhea, irritability, purple gums, decreased resistance and slow growth and development. In addition, some popcorn also adds a lot of saccharin, which is not good for the body. Therefore, parents should not let children eat this kind of popcorn often.
Nowadays, in order to make the taste of popcorn more attractive, a lot of margarine is added, and some flavors of popcorn will be added. In order to make the popcorn more beautiful, some pigments were added to it and he was dressed in a beautiful coat.
However, this margarine brings us extra energy and trans fatty acids. The extra energy will bring obesity closer to us. Trans fatty acids will 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.
Of course, as long as we pay attention to it, additives can still bring us a lot of delicious and fun.
With the progress of science and technology, the popcorn machine has also been greatly improved. Now the popcorn machine made of stainless steel has gradually replaced the converter-type machine in the past; The popular aluminum popcorn machine in previous years has been gradually replaced by stainless steel popcorn machine with people's understanding of the harm of aluminum tableware, and the pollution in production has gradually disappeared.
Many high-grade popcorn is made from non-trans fats such as coconut oil and palm oil, and corn itself is rich in nutrients, which can make popcorn delicious and nutritious, so it can also be very healthy!
Popcorn is processed from corn, and it is also a common snack. Many people especially like to eat popcorn. Popcorn is very sweet, and you don't want to stop eating it. Popcorn produced by regular production and processing can be eaten in moderation! But you can't eat too much popcorn. Eating too much is easy to make people gain weight. Children should eat less popcorn, and don't eat popcorn that is too fragrant!
