Pure milk powder is obtained by dehydrating fresh milk, which retains most of the nutrients in milk. Milk is a nutrient-rich food, containing a variety of nutrients such as protein, fat, carbohydrates, vitamins and minerals. The nutrients in pure milk powder are similar to those in fresh milk, and although there may be some trace losses during the dehydration process, it is still rich in nutritional value overall. Pure milk powder can provide protein to help maintain the normal function of muscles and tissues; fat to provide energy for the body and maintain normal physiological functions; and minerals and vitamins such as calcium and vitamin D, which contribute to bone health and the normal functioning of the immune system.
