According to experts, the protein that our human body can absorb milk can reach more than 95%, so we usually see the high protein content on the milk packaging box, which shows that the quality of this milk is better and the taste will be more mellow than other milk with low protein.

And according to various news reports, the country has higher requirements for milk products. If the protein content of milk is less than 2.8 mg/1ml, then this bottle of milk will fail. Therefore, when choosing milk, it depends on whether the protein content of this milk is higher than 3mg/1ml. protein is definitely one of the requirements for us to judge whether a bottle of milk is of high quality.

the second thing to pay attention to is the calcium content, which is also a very important indicator for us to judge the quality of milk. Just like the protein content, the higher the calcium content, the more it is worth buying. Normally, the calcium content of every 1 ml of ordinary milk should be between 9 mg and 12 mg, and the premise of this standard is calculated without adding artificial calcium.
