How long can milk powder be stored after opening the lid

Milk powder is a necessary food for babies. The quality of milk powder will also affect the child's physical health to a certain extent, especially some expired and deteriorated milk powder, which will cause symptoms such as diarrhea in children and should no longer be fed to children. The shelf life of milk powder begins after the cap is removed. So, how long can the milk powder be stored after the cap is removed? The following is a detailed introduction to the relevant knowledge!

1. How long can milk powder be kept after opening the can?

Infant formula powder is not sterile. If the opened formula is not consumed within three weeks (21 days), the formula can only be kept for a maximum of one month after opening the can, because the nutrients in the formula will not be much after a month as the nutrients are lost.

If the milk powder is more than 21 days old but less than 60 days old, adults can eat it. However, it is best not to eat it if it has been opened for more than two months.

2. What should you pay attention to when storing milk powder after opening the can?

1. Milk powder should not be stored in the refrigerator after opening. Milk powder is placed in the refrigerator and taken out again and again. The temperature and humidity differences inside and outside the refrigerator can easily cause the milk powder to deliquesce, clump and deteriorate. Opened milk powder can usually be stored at room temperature, away from light, in a dry, cool place.

2. For canned milk powder, be sure to close the plastic lid tightly after opening the can each time. Tie the bag tightly after each use of bagged milk powder.

Warm reminder: To facilitate the storage and removal of milk powder, it is best to store the bagged milk powder in a clean milk powder can after opening. Wipe the milk powder can with a clean and dry cotton towel before use, and do not wash it with water.

3. There are regulations on the usage time of milk powder after opening. Most infant formula packaging clearly states that the formula should be used within one month after opening. After opening, it should be discarded if it is used for more than one month. It is worth reminding that the shelf life on the milk powder packaging is the date when it is unopened and stored under appropriate conditions. Once opened, this date cannot be used.

4. Milk powder may also clump within the specified use-by date. Normal milk powder should be loose and soft. After opening, milk powder may become damp and hygroscopic, and easily clump, due to the entry of moisture from the air or the inevitable introduction of a small amount of water droplets during the preparation process of the milk powder. If the lumps break up easily when squeezed, the quality of the milk powder will not change much.

Warm reminder: However, if the lumps are large, hard, and cannot be broken up, it means that the quality of the milk powder is poor and should be discarded.

3. Misunderstandings about preparing milk powder

Mineral water and purified water are cleaner and safer than tap water

We recommend using tap water to mix formula milk. Mixing milk with mineral water can easily cause constipation in babies, and purified water does not contain any minerals and is not suitable for the baby's development and growth.

Most household tap water has been processed by water plants and its quality meets the standards. After boiling the tap water, let it cool to about 40°C and then use it to make milk powder. Purified water has lost the mineral elements of ordinary tap water, but people's absorption rate of calcium from water can reach over 90%, so it is not suitable to use purified water to make milk. Mineral water contains a lot of minerals and is complex.
