Grandma at the market told what to do to keep the milk fresh for a long time and not sour

If your child likes fresh homemade milk, then, perhaps, you have wondered why the milk sours at the moment when you want to give them a baby and need it to stay sweet and tasty longer? Steamed milk is usually stored for at least a day or even two, if you keep the jar in the refrigerator or other cool place. Then it needs to be finished or boiled, because then the product can curl up during heat treatment. And this indicates that the deadline has expired and the contents of the bank have soured.



But sometimes you have to worry ahead of time. Bring home morning (according to the seller) milk, boil to make your baby porridge or yogurt, and it boils. Do you want to know why milk is souring early? The reasons why it loses its qualities can be different. Let's list some of them.

Prematurely sour home milk in the case when an unscrupulous seller sells deliberately stale products, that is, yesterday’s oodle. In the cold season, some merchants sell milk two days ago, or even older. Only a few admit that it is suitable only for kefir.

It goes without saying that after a certain time, the natural product must necessarily sour: lactic acid bacteria multiply in milk, and as a result of their activity lactic acid is produced, from which the protein gradually folds and serum separates. The higher the storage temperature of dairy products, the faster they deteriorate. It is good that sour milk does not come into complete disrepair, but turns into a dairy product from which you can collect sour cream, get kefir or warm cottage cheese.



Steamed milk will sour too quickly if you pour it into unwashed dishes or strain through unwashed gauze. Milk must be placed in a clean and dry container made of a material that is not oxidized. It is suitable for a vessel of glass, clay, stainless steel or with an enameled coating.

It is recommended to buy dairy products from a familiar hostess, the cleanliness of which you do not doubt. If she does not care for the cow, carelessly washes the udder before milking or uses a dirty bucket, then the milk from her hands will lose its freshness early.



It is better to buy milk in glass jars with a capron cover, although this is impractical. So it retains its freshness longer, sour cream rises better on it, and it will be more. If you buy milk in plastic utensils that are reused, I advise you to choose bottles from ordinary mineral water. Try to avoid plastic in which there was a sweet drink, and do not take milk in beer containers.



What to do so that the milk does not sour as long as possible To keep the milk fresh for a long time, it must be quickly cooled and put in the refrigerator, tightly covered with a lid. It is also well stored in boiled form.

When it is necessary to extend the shelf life of milk, it can be frozen. If after defrosting it has lost a homogeneous consistency, warming or boiling will help to correct the situation.



To prevent the milk from getting sour, some housewives advise adding a pinch of soda, salt or sugar to the jar. I’ve never done this before, so I won’t say it works.



In the old days, milk was stored in the cellar. To prevent it from souring longer, a frog was lowered into a jug. People thought that cold-blooded amphibians cooled milk, so it did not sour. Later, scientists found that the skin of the frog secretes special substances that slow down the reproduction of lactic acid bacteria. This may be true, but I don’t want to check.
