The weather is cold, and drinking room temperature milk may cause diarrhea in the child's stomach, but he is worried that it is too cold. If milk is heated, on the one hand, there is a concern about nutrient loss, and on the other hand, it can be dangerous if it is not heated properly.
Recently, while browsing the circle of friends, I saw a friend share her experience of ** after heating milk in the microwave. She was creative in her way of heating: she didn't want to wash the cups to save trouble, so she cut open the top end of the milk carton and put it directly in the microwave.
To her surprise, the milk burned in the microwave for ......She specially reminded everyone in her circle of friends: never put milk directly in the microwave.
Inspired by a friend's circle of friends, Wenwen's father decided to search the Internet for information about "milk heating", as the child often drinks milk. After looking it up, he was surprised to find that if the following three mistakes were made during the heating of milk, not only would the nutrients be lost, but also the toxins could be generated, turning "hot milk" into "poisoned milk".
01. The three major taboos of heating milk must be avoided.
If you're still using these three ways to heat milk, be sure to stop!Otherwise, the nutrients of the milk will be lost, and it may also become "poisoned milk", which will cause harm to the child's health.
Milk is brought to a boil and heated.
Some parents pour milk directly into the pot and boil it for convenience, and this heating method is completely wrong!According to a study by the Academy of Agricultural Sciences, if the milk is heated for more than 62 years, the protein and calcium in it will coagulate into a gel and be deposited at the bottom of the pot.
As a result, key nutrients such as B vitamins, proteins, and calcium in milk can be lost due to heating, resulting in a significant reduction in its nutritional value. Therefore, it is important to remember that milk should not be poured directly into the pot and boiled, otherwise it will be drunk for nothing.
Heat the milk carton directly in the pot.
Inadvertently, Wenwen's father often uses this method to heat the milk, filling a small milk pot with water, putting the room temperature milk whole into the pot, and then placing it on the fire to heat it.
After checking the information, I learned that this way of heating milk is equivalent to drinking "poisoned milk". This is because the innermost layer of the milk carton is polyethylene aluminum foil, which is intolerant to high temperatures and boiling in hot water will release harmful substances into the milk.
Therefore, the heated milk not only loses nutrients, but may also have a negative impact on human health, and the gains outweigh the losses.
Microwave heating, there is a danger.
Just like the friend in Wenwen's father's circle of friends, obviously to save trouble, he put the milk directly into the microwave when he got up in the morning, but it almost caused **.
Why does the milk carton burn and even ** when heated directly in the microwave?Anyone who knows the material of milk carton packaging understands that milk carton is mainly composed of paper, plastic polymers and aluminum foil on the inner wall. Items made of this material are not suitable for direct microwave heating, otherwise the high temperature will produce sparks and cause combustion.
Therefore, heating milk directly in the microwave oven may slightly damage the microwave oven, and in severe cases, it may lead to**, or even start a fire. Therefore, it is important for everyone to pay extra attention!
How many of the above three pitfalls have you encountered?Now that we know the wrong heating method, what is the correct heating method?
02. Three correct methods of milk heating, be sure to keep in mind.
Everyone knows that milk is rich in protein, vitamins, calcium and other rich nutrients. So, how do you heat it to avoid the loss of these nutrients?
CCTV Life Tips" column group has professionally tested the effect of milk heating on nutrients. The results showed that during the milk heating process, the nutrients did change somewhat as the temperature increased.
When the heating temperature of milk exceeds 62, the lactoferrin, vitamins and proteins in milk will be significantly affected. The longer the heating time and the higher the temperature, the more severe the nutrient loss.
Therefore, in order to keep the nutrients in milk from being lost, it is important to know the heating temperature and duration. There are three correct methods of milk heating to keep in mind:
The first is to use the waterproof heating method.
First of all, boil an appropriate amount of hot water, and control the water temperature at about 60;Then put the room temperature milk carton in hot water and heat it for 5-6 minutes to reach the right temperature.
Heating the milk in this way ensures that the milk is kept at a temperature of around 40 °C at the intake, thus effectively retaining the rich nutrient content of the milk.
Special care should be taken not to use boiling water, as the innermost layer of carton milk is polyethylene, which is intolerant to high temperatures. The use of hot water that is too hot may result in the release of toxic substances.
The second method is to use a microwave oven for heating. Although the previous article may lead one to think that microwave ovens are not suitable for heating milk, this is not the case. As long as the microwave is used correctly, it is perfectly possible to use it to heat milk.
When using the microwave to heat the milk, first pour the milk into a special container, then place it in the microwave and heat it over medium-low heat for 1-2 minutes.
It is important to remember not to heat the microwave for too long to avoid the milk being too hot. At the same time, when heating milk, the container should not be covered with a lid. Finally, unopened packaged milk should not be placed directly in the microwave.
The third method is to use a pot for milk heating. First make sure the small milk pot is cleaned, then pour the milk into the pot and heat it slowly over low heat. While boiling milk, be sure to stir while boiling to prevent the milk from clumping. When the surface of the milk starts to bubble, turn off the fire in time.
Some scholars believe that in addition to the need to heat milk slightly in winter, it is recommended to drink room temperature milk directly in other seasons, which is more conducive to providing comprehensive nutritional supplements, especially for children, complete milk nutrition is more beneficial to their growth and development.
