Is it better to drink milk, raw or cooked, please 3Q

Milk contains a large amount of high-quality protein (including 8 kinds of amino acids essential to the human body), but also contains fat, lactose, vitamin K and inorganic salts calcium, phosphorus, etc., rich in nutrition, easy to digest and absorb, is the first choice of milk substitute for infants lacking breast milk, and is also the best nutrition for children, the elderly and the infirm. At present, dairy factories in many cities have updated their equipment and innovated their technological processes, using plastic film bag packaging and high-temperature instantaneous sterilization to replace the long-standing bottled and pasteurized method (i.e., heating to 60 for 30 minutes), which not only keeps the nutrients in the milk from being destroyed, but also achieves the purpose of disinfection and sterilization. We have seen many people drink milk in an unreasonable way, which is manifested in the following aspects:

1. Bring to a boil and drink. Boiling will cause the protein in the milk to denature, and the particles will become larger, which will hinder digestion and absorption. In fact, the bagged milk has been strictly purified and sterilized to ensure safety, although it is safe to drink, why boil, just put this bag into hot water and soak it for 5 10 minutes, and you can drink it.

If it is heated directly, it should be mastered at 70 80 is appropriate. 2. Cold drinks. In the cold season, milk should not be drunk cold, as this will promote gastrointestinal peristalsis and cause diarrhea.

3. Drink on an empty stomach. Milk should be eaten with bread, steamed bread and other pastries, and drunk on an empty stomach, as the milk will be quickly discharged into the large intestine through the stomach and small intestine, and the nutrients will be excreted from the body before they have time to be absorbed. 4. Store for too long.

Fresh milk should be taken and drunk, and if it needs to be put in the evening or on the second day, it should be placed under the condition of 0-5 to avoid spoilage or destruction of nutrients.

The raw is nutritious, and if it is in the height increase period, it is especially obvious to drink it often to grow taller.

Milk is still boiled and drunk, because, there are harmful bacteria to people, it is better to boil it hot, after quoting.

Boiling milk over low heat: it will destroy the vitamins in the milk by oxygen.

Boiled milk: Milk is rich in amino acids, at high temperatures, the amino acids and sugar in the milk form fructose-based amino acids, which are not only not digested and absorbed by the human body, but will affect human health, and the colloidal protein particles in the milk will be dehydrated into a gel at 60. The phosphoric acid in milk precipitates from acidic to neutral at this temperature.

Therefore, the heating temperature of milk should not be too high, when heated to 100, the color, aroma and taste of milk are not only reduced, but also the nutritional value is greatly reduced!

So, how do you heat milk properly? In fact, it is most appropriate to use the water insulation heating method. If you use a microwave oven to heat it, be careful not to use it for a long time, because the temperature is high, the nutrients of the milk will still be destroyed, and you should also pay attention to the uneven temperature when using the microwave oven, so you should shake it before drinking it so that it will not be burned.

In addition, people who like convenience often choose milk powder, the nutritional content of milk powder is similar to fresh milk, when brewing milk powder, pay attention to the temperature of the water should not exceed 60.

1. Raw milk has higher nutritional value.

Pure milk and raw milk are different dairy products, among which raw milk is fresh milk that has just been squeezed out, and raw milk has not been filtered and sterilized, so the nutritional value contained in raw milk is more comprehensive.

Pure milk is a dairy product produced after filtration, sterilization and other processes of milk, and some pure milk will be skimmed or added with other additives, and the nutritional value of processed pure milk is relatively lower, but pure milk is relatively easier to be absorbed by digests quietly, because it contains simple nutrients.

2 No, you can't. Because raw milk is freshly squeezed milk, it is a dairy product that has not been transported to any treatment, although the nutritional value is more comprehensive, but the corresponding bacterial substances will be more, and drinking it directly may harm your health, such as abdominal pain, diarrhea and other discomforts.

Therefore, raw milk cannot be drunk directly, especially for some people with weak constitution, lactose intolerance, and weak gastrointestinal digestion, it is not recommended to drink raw milk directly.

3. Need to boil.

Raw milk is a raw dairy product, not sterilized, so it can not be eaten directly, it needs to be boiled and sterilized before drinking, and the temperature of raw milk can not be too low when cooking, otherwise it will not play the due bactericidal effect, but the temperature can not be too high, which will cause a large amount of nutrients in raw milk to be lost.

You can pour raw milk into the pot, first turn on high heat and cook until it boils slightly, then immediately turn off the fire cover, and then turn off the fire again after a while, and then turn off the heat when it boils slightly, so that the raw milk can be cooked 3-4 times.

4. Look at the temperature at the time of cooking.

Raw milk is fresh milk, so it must be boiled before drinking, and the specific boiling time depends on the temperature of the boiled milk, if you cook it at home, you can boil the milk for 25 seconds, but if it is sterilized by pasteurization, it will take about half an hour.

Because the temperature of boiling raw milk also depends on the speed of bacteria being killed, if the temperature of boiling milk reaches 100, the bacteria in raw milk can be killed within half a minute; However, if it is a low-temperature sterilization, that is, pasteurization, such as about 60, it takes about half an hour to kill the bacteria in the raw milk.

Cooked well, raw not only bacteria, the protein in it is also not conducive to human absorption, after cooking, the protein is denatured, it is converted into conducive to human absorption.

Cold milk! Some people have a habit of warming up milk before drinking it, but in reality, the higher the temperature of the heat, the longer the milk loses more nutrients. Fresh milk is the most nutritious, so it is recommended to sterilize the milk with a daily schedule.

Although bus milk has a short shelf life, it is definitely the freshest and most nutritious. The longer the milk is stored, the less nutritious it will be.
