How to skim milk properly?

Whole cow's milk tastes amazing. It is also good for health. People who cannot tolerate high-fat foods or are on a diet opt ​​for skim milk. How to make low-fat milk at home, as well as how it is defatted in production, will be discussed further.

Peculiarities

Skimmed milk is a product containing 0.1% fat. It can be obtained using a special apparatus designed to separate cream from milk (separator). Skimmed cow's milk is consumed as a finished food product or used as a component in the preparation of various dishes, such as omelettes, pastries, cocktails.

Skimmed milk retains many vitamins and healing components that a person needs for a full life. The composition of such a product includes potassium, magnesium, copper, calcium, iron and many other elements. The fat-free product also contains vitamins D, C, A, B, E, etc. This set of vitamins helps to actively strengthen the human immune system. At the same time, the calorie content of the product is only 35 kilocalories per 100 grams.

Industrial degreasing technology

The procedure for defatting a product in a dairy consists of several steps.

  • Fresh products are poured into cans and cooled so that their shelf life is significantly increased. After that, the milk is sent to the factory for processing.
  • At the factory, it goes through a stage of processing on a separator for cleaning from bacteria and dirt at a temperature of 45 degrees Celsius.
  • Then the product is driven through special apparatus for the separation of cream and skimmed milk, which is also called "reverse". As a result, the fat content is reduced to 0.1%.
  • After that, the reverse goes through another processing to create a more homogeneous structure.
  • An obligatory step is pasteurization, which consists in heating the product to 65-90 degrees Celsius for re-cleaning of contaminants.
  • At the final stage of production, the product is cooled and poured into special containers. Then it is sent for sale to retail outlets.

On packs of pasteurized milk, a shelf life of up to 7 days is usually indicated at a temperature of 2 to 5 degrees Celsius. With an increase in temperature, the shelf life of the product is reduced.

Skimming milk at home

According to the generally accepted typology, the reverse has a fat content of 0.1% or less. Therefore, it is important to note that it will not be possible to obtain such a low percentage of fat content at home due to the lack of special equipment used in the dairy.

Various methods can be used to obtain a fat-free product. The hot method gives faster results, while the cold method has a slower effect. Let's consider them in more detail.

hot way

Whole milk should be poured into a saucepan with a thick bottom. On a low heat, you need to bring the product to a boil, after which you should remove the pan from the heat and cool its contents. With this approach, the cream will go up, they can be removed with a spoon. So you get a product with a lower degree of fat content.

cold way

If there is not enough milk, then you can pour it into a container with a wide neck, or into a deep plate. The container should be placed in the refrigerator for 10-12 hours. During this period, a natural process of separation of milk and fatty parts will occur. Then the cream can also be simply skimmed off with a clean spoon.

At home, you can cook obrat with a mixer. Pour whole milk into a tall container, lower the mixer there and turn on the highest speed. After a while you will be able to see small lumps. This is how the process of separating fat occurs. After that, you will only need to strain the liquid through cheesecloth. The result is butter and skimmed milk.

Benefit and harm

The main advantage of a low-fat product is that it can be eaten during a diet. Such a drink helps to strengthen the skeletal system, improves the functioning of the cardiovascular system, regulates the metabolism in the body.

However, according to some doctors, skimmed milk is significantly inferior to whole milk. When milk fat is removed, the amount of vitamins is also reduced, which are many times more in whole milk. It is also worth considering that any dairy product contains lactose, therefore people with an allergy to this component should refuse to use even a low-fat version.
