Can milk be heated at high temperatures, can milk be heated at high temperatures?

Can pure milk be heated? Let's take a look.

No. Milk at room temperature, the enzyme is inactivated, after high temperature heating, the enzyme will be activated, which will lead to a part of the protein precipitation, if cooled, heated and activated again, it will lead to more protein precipitation, and even the formation of tofu brain. This kind of milk, the nutritional status is completely changed, although it is non-toxic, but it is not recommended to drink.

So, still don't heat it anymore.

First, let's take a look at how milk changes when heated.

1. After the protein in milk is heated at high temperature, it will change from a sol state to a gel state, and precipitate will appear, thereby reducing the nutritional value.

2. Milk contains lactose, and milk will produce lactic acid, acetic acid, and formic acid after being heated at high temperature. The balance of ions is broken, the milk turns brown, and caramelization occurs.

3. Although the fat in milk does not undergo chemical changes at high temperatures, the globulin in milk combines with fat, making the cream difficult to decompose.

4. In the process of heating milk above 63, the calcium and phosphorus in it combine to form calcium phosphate precipitate, which is difficult to dissolve.

5. After high temperature heating, water-soluble vitamins will be affected. For example, there is a large loss of vitamin B and vitamin C in milk.

6. There are many people who like to heat up with packaging bags. Although milk pouches are safe for normal use, the main component of the packaging material is polyethylene. At temperatures of more than 115 degrees, this ingredient decomposes and changes, dissolving harmful substances and threatening our health.

From the above analysis, we can conclude that the nutritional value of milk is not only reduced after high temperature heating, but also produces substances that are difficult to dissolve. However, heating with packaging is more likely to produce harmful substances and threaten health.

So, what should people who like to drink hot milk do?

1. Pasteurized milk bought in supermarkets and other formal channels can be drunk directly without heating. If you are not used to drinking cold milk, soak the bag of milk in warm water for a few minutes.

2. If the milk is poured into a container and heated on a gas stove, the heating temperature should not be too high. The milk can be drunk warm and does not need to be boiled.

2. Try to buy milk with a short shelf life, buy and drink now. The shorter the shelf life, the fresher the milk. The more nutrients are retained by low-temperature sterilization.

3. The unpacked milk should be drunk at one time, and the longer the storage time, the more nutrients will be lost.

Milk can be heated. You can drink it warm, but don't let it boil too fast or it will overflow. It can also be used as a food ingredient to make bread and cakes.

It can be heated, and the milk tastes better when heated.

Can be heated. Don't drink raw milk, drink fresh milk at high temperature to prevent illness from entering the mouth;

Some people are accustomed to drinking milk on an empty stomach to prepare for hail, which is not scientific. Because eating on an empty stomach, the bowels move quickly. In addition, the protein in the milk will be quickly converted into energy and consumed.

The nutrients in milk are not yet digested. Absorption, it is discharged to the large intestine, invisibly causing waste. It is best to eat something before drinking milk or drink while eating food.

80% of the protein in milk is casein, when the pH of milk is below, a large amount of casein will agglutinate, precipitate, difficult to digest and absorb, and in severe cases, it may also lead to indigestion or diarrhea. Therefore, acidic drinks such as fruit juice should not be added to milk.

Some people like to use milk instead of boiled water to take medicine, in fact, milk obviously affects the absorption of drugs by the human body, milk is easy to form a covering film on the surface of the drug, so that the calcium, magnesium and other minerals in the milk react with the drug chemically to form non-water-soluble substances, thereby affecting the release and absorption of the efficacy of the drug. Do not drink milk 1 hour before and after taking the medicine.

It is not advisable to drink more cold milk, because cold milk will affect gastrointestinal motor function, cause mild diarrhea, and make most of the nutrients in milk unable to be absorbed and utilized by the human body.

Milk can be heated. Heating does not affect the nutrients in the milk.

There are mainly proteins and trace elements in milk, heating denatures proteins, but denatured proteins can be absorbed by the human body, boiled eggs are also protein denaturation processes, high temperature will not affect the quality of trace elements, may affect the quality of some vitamins, but the vitamin content in milk is very small.

Milk can be heated, but the temperature is easy to drink just right, too high a temperature will destroy its nutrients, and it is best to drink fresh milk is the kind that is delivered every day. When the milk is heated to 130 degrees Celsius, it is fully sterilized, but at the same time it loses its nutrients. However, heating at home generally does not reach such a high temperature, and if it is heated to a temperature, the nutrient loss is not large.

Benefits of Drinking More Milk:
