Milk powder is generally stored for one month after opening, because infant milk powder is rich in nutrients and high in protein, and rich protein and a variety of nutrients are also one of the reasons why bacteria are easy to breed. Milk powder that has been opened repeatedly and has been in contact with the air many times may be contaminated by bacteria in the air, and some nutrients are also prone to oxidation and deterioration. The temperature and humidity of the milk powder will change when the can is opened repeatedly, which can easily cause moisture, caking and deterioration of the baby milk powder.

After opening, the milk powder is usually stored at room temperature, away from light, dry and cool place, and should not be stored in the refrigerator to avoid greater humidity and temperature changes. After each use, the canned milk powder must be tightly covered with a plastic lid, the bag mouth should be tied tightly, the milk powder should be taken and placed, and the hands should be dried to avoid the milk powder getting wet.
