Milk is a special nutritive substance. Everyone should drink more milk every day to supplement his body's nutrition, but sometimes he can't drink cold milk. When he drinks a little in winter, he feels like he has ice in his normal temperature, so it's necessary to heat the milk. Sometimes he needs to do double skin milk or ginger juice to collide with the milk, so how to boil the milk is Is science right?
The first point: it is not suitable to cook milk for too long. Milk must not be boiled for too long, because the nutrients contained in milk are easily damaged by air oxidation, thus reducing the nutritional value of milk. Someone will say, can I solve it quickly with high temperature? The answer is No. But it should be noted that milk is also not suitable for cooking in high temperature. It's wrong for some people to cook milk in high temperature for a long time in order to disinfect thoroughly. The protein contained in milk is easy to be destroyed under high temperature. In addition, there are some extremely unstable phosphates in the milk. Under high temperature, the acid phosphates will be converted into insoluble neutral. In this way, the quality of milk will be greatly reduced. Therefore, milk should not be cooked in a slow fire, but not in a high temperature for a long time.
Second point: soymilk and milk can't be cooked together. Soymilk and milk are nutritious food. Some people have come up with the idea that if I cook these two foods together, it will increase the overall nutritional value, which is wrong. You should know that although soymilk and milk need to be heated and boiled for drinking, they have different ingredients and different natural cooking methods. Soybean milk contains trypsin inhibitor, which can stimulate gastrointestinal tract and inhibit trypsin activity. If the soymilk is not boiled, it is easy to cause poisoning. The milk only needs to be boiled at low temperature. If it is boiled at high temperature continuously, the nutritional elements in the milk will be destroyed, thus reducing the nutritional value of the milk.
The third point: it is not suitable to add sugar when boiling milk. Some people are not used to pure milk, so they will add some sugar when they cook the milk. They will think that the milk cooked in this way is sweet and delicious. In fact, this is the wrong way. Because, add sugar when boiling milk, lysine and fructose in milk will produce a toxic substance -- fructose lysine under high temperature. This kind of substance can hurt people's body and cause diarrhea. So don't add sugar to boiled milk.
