Everyone has known milk since childhood, both in liquid and in powder form. Today, when every second began to think about a healthy lifestyle, many say that before using it, it is necessary to skim milk powder. However, this also applies to a conventional liquid product. Let's talk more about the benefits of degreasing.
Features
Such a product is obtained by separating (in other words, separating) ordinary milk to extract milk fat from it. As a result, 90% of the initial mass remains. 70% of solids and 99% of vitamins and other minerals pass into skim milk. In fact, such a product is no different from the whole. The exception is fat soluble vitamins. They are not available in the revised version. In general, the proportion of fat in it should not exceed 1.5%.
Skim milk: benefits or harms
Specialists were divided into two groups: some zealously protect the product, the second, on the contrary, insist on its harm. You can argue about this for a long time, but the truth is this: milk with a lower fat content is simply necessary for people suffering from obesity or atherosclerosis. Its use is useful for diseases of the kidneys, as well as during dieting.
How to degrease homemade milk?
Currently, supermarkets in large cities offer us milk for every taste. The fat content in it can vary from 1.5% to 6%.
But it is in large cities. And what should residents of small towns and villages do, where there is no such choice? Milk there is sold very oily. The mass fraction of fat is usually not less than 3%. The answer is simple: learn how to skim milk, and do it yourself.
Let's talk about one of the easiest ways. You will need gauze, a wide-necked container (an ordinary jar is suitable), a mixer.
- Leave the milk in a cool place for a day and forget about its existence.
- The next day you will notice that the fat part has risen up. This is cream (they can be used to make sauces, cakes, instead of sour cream).
- Carefully remove the top. All that remains below is skim milk.
- If it seems to you that the product is fat after that, beat it with a mixer at high speed. Fats turn into small pieces of oil.
- Strain the whipped milk through 4-ply cheesecloth. The greasy part will remain on the canvas. Such a product has indicators of fat content - 1.5-2.2%.
Powdered milk
It comes in 3 types: whole, instant and fat-free. They began to use a powder product a long time ago, back in the 19th century. But one must be careful, because not always such a powder can be of high quality. Few people think about how to skim milk powder. And in vain. Some manufacturers add deodorized vegetable fats to it, rather than milk fat. Determining the composition of an inexperienced buyer is difficult, and almost impossible. Therefore, it is better to give preference to trusted brands.
Skimmed milk powder production
The production of milk powder is delivered to the conveyor today and does not create any special difficulties. According to the method of production, it is of 2 types:
- Spray. It is produced by spray drying.
- Film. Drying takes place on roller plants.
The first production method is most in demand, it is also called spray drying.
- The milk is filtered, then separators come into play and the fats are separated from it.
- Next comes the pasteurization process, which is carried out to disinfect the product.
- The prepared milk is cooled, then evaporated and homogenized.
- The next step is to spray dry the product.
- After this operation, it is sieved and cooled.
As you can see, manufacturers do not have a special task - to skim milk powder. Everything happens in the production process.
The use of milk powder
Today, a powdered product is quite popular. It is used in many industries and is present in:
- confectionery products;
- bakery products;
- baby food and dry mixes;
- drinks (we are talking about therapeutic cocktails);
- alcohol products.
Also used in cosmetology (for the production of creams and masks), in agriculture (as animal feed).
Powdered milk can be eaten. To do this, it is diluted with warm water in a proportion of one to three. It is better to drink it early in the morning or late in the evening. Sometimes cardamom or fennel is added to the prepared drink - substances that calm the nervous system.
Fat-free milk powder means saving yourself from health problems. In addition, a drink from such a product perfectly saturates and kills the feeling of hunger. Be that as it may, skim milk has many beneficial properties. And in some cases, its use is simply necessary.
