A solid beverage refers to a solid product made of sugar, milk and dairy products, eggs or egg products, fruit juice or edible plant extracts as the main raw materials, and an appropriate amount of auxiliary materials or food additives. Milk powder is a blended food made from fresh milk or goat's milk by freezing or heating, removing almost all the water in the milk, drying and adding proper amount of vitamins and minerals. The raw materials are different, so solid drinks are not milk powder.

Milk powder is made from milk of cattle, sheep or other animals through disinfection, degreasing, dehydration and drying. Milk powder is a reprocessed product, not an original food. It is suitable for storage and easy to carry, and it can be used for brewing and drinking, food processing, canned drinks and other purposes with proper amount of vitamins, minerals and other nutrients. There are two kinds of genuine milk powder, one is domestically produced genuine milk powder, and the other is imported milk powder that meets the standards of China.
