When buying milk at ordinary times, if you want to distinguish between good and bad, you can look at the ingredients list of milk. The first ingredient in the food ingredient list is that this food contains the most materials, so if you look at the ingredient list of milk, its first ingredient must be fresh milk. If other ingredients are in the first place, it means that this milk is of poor quality and low purity, and it is not easy to buy and drink.
Step 2 smell it
You can smell it when you buy milk at ordinary times. There is a great difference in taste between good quality milk and poor quality milk. Fresh and high-quality milk, with strong milk flavor and rich milk fragrance. If you find that the milk tastes very weak when you buy it, it means that the milk is mixed with other ingredients, and the quality is not pure, so it is not easy to buy.
Step 3 look at the state
Usually after buying milk, you can take a small amount of milk and add a little water. If there are some solid substances at this time, it means that this milk is not fresh. In addition, you can also drop milk on your nails. If milk is spherical, it means that milk is fresh. If it is scattered soon after dripping, it means that this milk is not fresh.
