Is milk powder milk? By freezing or heating, almost all the water in milk is removed and dried into powder. After being diluted with water, it can be automatically dispersed into powdery solid suspension for molding. For pesticides with low melting point and difficult to be processed into powder or wettable powder, it is suitable for processing into milk powder.
What's the difference between milk powder and milk powder? The names of "milk powder" and "milk powder" are very similar, but in fact there are differences. What is the difference?
1, different processing methods
Milk powder is made by freezing or heating to remove almost all the water in milk, and then drying.
Milk powder is a powder made by removing water from milk, which is suitable for preservation. Milk powder is a mixed food made of fresh milk or goat's milk by freezing or heating, removing almost all the water in milk, drying and adding proper amount of vitamins and minerals.

Which is better, milk powder or milk? Fresh milk is a complex emulsion, which is mainly composed of water, fat, protein, lactose, minerals and vitamins. The water content accounts for 86%~90%, so its nutrient content is relatively low compared with other foods. The average specific gravity of milk is 1.032, which is related to the solid content in milk. The composition of milk is basically stable except fat content, so the specific gravity can be used as a simple index to evaluate the quality of fresh milk.
The content of protein in milk is 2.8%~3.3%, which is mainly composed of 79.6% casein and 1 1.5% casein.
Milk whey (white) protein and 3.3% lactoglobulin, and a small amount of other protein, such as immunoglobulins and enzymes. Among them, milk protein precipitated at 20℃ and pH4.6, which is called casein. Casein is a heat-resistant protein, but it will precipitate under acidic conditions. Yogurt and cheese are made according to this principle. Casein combines with calcium and phosphorus in milk to form casein colloidal particles, which exist in milk in the form of colloidal suspension.
Milk powder is made of freshly squeezed milk and dried through a series of processes. Rich in nutrition, it can supplement beneficial bacteria to adjust the nutritional balance of intestine.
