the milk Commonly contains the necessary protein and calcium to grow bones and cells, especially in children, but how is milk drying? Do the basic components of powdered milk compare to other types of milk such as liquid milk? Is it a health hazard caused by the consumption of powdered milk?
The process of manufacturing powdered milk or drying milk in several stages and processes of liquid milk, which is in the final stages of the drying agents, to learn together these stages:
- Milk is obtained from dairy farms where milk is obtained from some farms. Milk is manufactured and marketed, or some of it goes to the milk powder factories. Milk enters a special filter to be inspected and then checked for quality standards. Milk is introduced into a special temperature incinerator, in order to remove some ratios of water to increase the proportion of solids in it to up to 50%.
- Milk is then introduced in a pasteurization process to reduce the bacteria under a temperature of about 79 degrees Celsius for twenty seconds to be cooled. The milk is then separated from any layers that may appear on the top surface of the cream and others, and these layers are kept for other purposes. Milk is then standardized and homogenized depending on the proportions of the solids depending on the type of milk to be processed, whether full fat, low fat and fat free.
The remaining milk is used in the milk powder industry through two different methods:
- The first method is drying the roller roller, and the milk sprinkle a large cylinder and the presence of appropriate temperature make the water ratios in the milk evaporates to keep the milk dried on the cylinder.
- The second method is the spray drying where the milk is sprayed in a room of suitable size and the hot air is poured on it, to dry the milk drops very quickly and fall down, and then scraped and packed in bags or appropriate packaging.
Both types of fresh milk and dried milk contain the same proportions of certain ingredients and ingredients. One cup of fresh skimmed milk or skimmed milk contains about 80 calories, 8 grams of protein and 30 percent Of the daily needs of calcium.
Some say milk drying makes milk more susceptible to oxidation, especially cholesterol, and oxidized cholesterol is harmful to cardiovascular health.
