Generally, milk can only be divided into two categories, pure milk and yogurt. Yogurt refers to fermented milk, which can be stored at low temperature for 7 to 265,438+0 days. It is better for adults to drink pure milk, because pure milk contains more protein and nutrients. Personally, I suggest drinking ternary pure milk. Because ternary pure milk belongs to our own cows, the quality is reliable. In the melamine incident in 2008, it was also the only well-known trademark enterprise in China that was not detected. For example, Yili Mengniu advertised well, but melamine was still found out. It's not true!
