pay attention to distinguishing milk beverage from milk
"first of all, we should pay attention to the category of food packaging bags. the label will inevitably indicate the category of food. the name of the category must be the standard name licensed by the state, which can reflect the essence of food." feng xuehang, head of the food production supervision department of the provincial food and drug administration, said. for example, if the beverage package is marked "coffee milk", to determine whether it is a beverage or a milk product, you can check the food label. if the "food category" item on the label indicates "flavored milk" or "flavored milk", the product is made by adding coffee and sugar to the milk instead of adding sugar, thickener, coffee and a small amount of milk to the water. if the latter is the case, then it belongs to "milk beverage" rather than milk in the food category.
