The main difference between Mengniu's concentrated milk and pure milk is its ingredients and processing. Mengniu thick milk is a kind of modified milk, 80% of the recovered milk as raw materials, and then add food additives or nutritional enhancers to make it. In contrast, pure milk is made by simply processing raw cow's milk without adding any other ingredients.

There is also an anhydrous cream added to the milk, which gives it an extra rich flavor. This is another difference between Mengniu's concentrated milk and pure milk. Anhydrous cream is fat from milk, which, like milk fat, is natural and contains fat-soluble vitamins found in milk, such as vitamins A, D, and E, which are needed for children's growth and development. However, because the fat content of this milk is higher compared to pure milk, people who are particularly mindful of fat intake need to choose carefully.
