How long should raw milk be boiled, and how long should fresh milk be boiled

Fresh milk has high nutritional value, and a glass of fresh milk every morning is a breakfast habit for many people. In the past two weeks, the weather temperature has gradually dropped, the temperature is getting lower and lower, and a glass of fresh milk at room temperature in the morning has made people feel cool. In today's weather, it is more suitable to drink fresh milk after heating.

Fresh milk has high nutritional value, such as: protein, fat, vitamins, calcium, iron, etc., and drinking fresh milk often has great benefits for human health. Heated fresh milk is gentler on the human stomach, but compared to unheated fresh milk.

Fresh milk after heating lasts for a relatively short period of time because some of its ingredients change, leading to a faster depreciation. Therefore, the heated fresh milk must be drunk as soon as possible, generally no more than 24 hours.

The heating time of fresh milk should be well controlled, generally in 3-5 minutes, because milk contains phosphate, if it is heated for a long time, it will form sediment, so do not heat fresh milk for too long. Pour into a bowl and heat in the microwave on high heat for 1 minute, or fresh milk boil for 2-3 minutes.

Fresh milk is stored for a long time in winter, as is the case with fresh milk that has been opened. In summer, it can be stored for about 2 hours at room temperature, and in winter, it can be stored for 1 day at room temperature. Bacteria grow more slowly and deteriorate more slowly in low temperatures.

High temperature heating will lead to a decrease in the taste and nutrition of fresh milk, if you want to avoid loss of nutrients and pure taste. It is more appropriate to pour fresh milk into a glass and put it in a container filled with boiling water.

Some people may have seen that the saying that milk will produce harmful substances when heated and boiled is wrong and has long been debunked. There are only two purposes for heating fresh milk, one is to sterilize and the other is to have a palatable temperature. The best milk on the market has been sterilized, as long as it is drunk within the normal shelf life, there will be no problem, and we don't need to deliberately "heat sterilize".

How it works:

01Hot milk helps sleep, so many people, especially the elderly, are accustomed to boiling the milk they bought before drinking. However, experts note that this approach is not advisable. At present, all the milk sold on the market is a product that has been heated and sterilized.

If the purpose of boiling is to sterilize, there is no need for this at all. Moreover, the temperature requirements for milk disinfection are not high, 3 minutes at 70 and 6 minutes at 60. Generally speaking, UHT milk can be drunk directly, and for fresh milk taken out of the refrigerator, because it is relatively cold, it is enough to heat it to a suitable temperature for drinking.

02If the milk is boiled and the temperature reaches 100, the lactose in the milk may caramelize, which will affect the taste and nutrition of the milk. In addition, after the milk is boiled, the calcium in it will precipitate with phosphoric acid, which will also reduce the nutritional value of the milk. Experts point out that the best way to warm milk is to heat it in hot water for about 5 minutes.

If you choose to use a milk pot to cook milk, it is best not to leave it all the time, because milk is generally heated to a certain temperature and is very easy to overflow.

03 It should be reminded that in order to save time, many people choose to use microwave ovens to heat, this heating method will cause uneven temperature, and bags and cartons of milk containing polyethylene are not suitable for microwave heating, and polyethylene will decompose when heated. Therefore, it is important to read the instructions on the package before heating. In addition, the setting time should not be too long, 250 ml can be heated for 1 minute, otherwise it will also destroy the nutrients.

04 In addition, some people like to drink tea while drinking milk, especially southerners. In fact, this drinking method is not scientific, because milk is rich in calcium ions, and some components in tea will hinder the absorption of calcium ions in the gastrointestinal tract and weaken the inherent nutrients of milk itself.

Fresh milk does not need to be boiled by itself, normal fresh milk has been processed, such milk can be eaten directly, but if you want to add it later, you can also take the way of heating.

Do you need to instruct fresh milk, if I call fresh milk, it should be better, because it can be disinfected and sterilized.

Hello, if it is fresh milk to drink, it must be cooked. Otherwise, it is easy to have diarrhea.
