A bottle of milk a day was able to create a real miracle and save a baby who had nothing to feed.

However, there are other stories that say that the child's body could not absorb the nutrients in the drink, and milk had to be replaced with other products. Most likely, parents already know how their baby tolerates lactose found in milk, and they know how it (milk) can be replaced in modern conditions. Everything that is written above was written about full and real milk.

From what age?

At what age can you give pasteurized milk to a child? Modern nutritionists are adamant. They do not recommend introducing store-bought dairy products into a child's diet before the age of three. The thing is that in a bottle of milk there may be various additives not intended for children's use. Although, most likely, a similar incident happens more often with cheaper products. Formula-fed babies are allowed to introduce pasteurized milk into the diet from the age of one.

What's the use?

And now let's remember what is the use of milk for the human body. Milk regulates the body's metabolism. It provides us with a decent amount of calcium, thanks to which the teeth and bones of a person remain for a long time strong and healthy.

According to GOST

And now about how they get pasteurized according to GOST. The product is heated up to sixty degrees. After one hour, the milk is rapidly cooled. Thanks to this method, drinking milk, pasteurized according to GOST, bacteria that can cause spoilage of the product die. At the same time, a large number of various pathogens that may be in a fresh steam product die.

The method is good because the milk remains almost as useful as if it had just been from under the cow. But fresh product would never have endured the road to the store, so that city children and adults could feast on them. And the shelf life of pasteurized milk is significantly increased compared to the shelf life of a fresh whole product.

About types of processing

Outlets today provide a wide range of dairy products. Before all that milk hit supermarket shelves, it had to go through some processing.

In addition to the pasteurized product, you can also find sterilized and ultra-pasteurized.

sterilized milk

The sterilized was subjected to heating (boiling) for several minutes. When asked how long milk is stored in the refrigerator if it has been sterilized, manufacturers say that ten days is not the limit. Even the absence of a refrigerator for milk that has undergone sterilization is not an obstacle. However, an opened bottle or other packaging is still recommended to be stored in a cold place.

UHT milk

UHT occurs at higher temperatures than pasteurization and sterilization. Milk during ultra-pasteurization undergoes instant heat treatment, being in temperature regime more than one hundred and twenty degrees, and immediately packed. Such a drink is able to stand without a refrigerator and not turn sour in a sealed form for at least six months.

Shelf life of pasteurized milk

And yet the most "live" product can only be considered pasteurized. It is subjected to less stringent measures to increase its shelf life than sterilized and UHT milk.

What will be the shelf life of pasteurized milk depends on the conditions in which it will be. It is also important that the package with milk is opened or hermetically sealed and has not been opened. If you brought from the store milk product, sealed in an airtight container, then it will last longer.

Inside, the packaging is arranged in such a way that it does not allow light to break through to the product and begin its destructive effect. And in the dark and cool, microorganisms multiply less willingly. In this case, the milk should not be opened and kept in a cool place.

If you had to keep the milk open, it must be placed in the refrigerator at temperatures from zero degrees to plus five. In this state, milk will be well stored for three days. Rigid packaging is equipped with a screw cap, stopping the strong flow of oxygen into the product.

Soft packaging

Soft containers shorten the shelf life of pasteurized milk. The thing is that such packaging does not have a lid that allows you to close the opened box. Air, of course, gets inside the bag, and microorganisms develop much more actively. Therefore, the shelf life of pasteurized milk in a closed soft container will be no more than three days. And the opened package ceases to protect the product after thirty-six hours. Milk turns sour after this time. However, it can still be eaten using in baking.
