How long can a newly opened can of milk powder be kept? Misconceptions about milk powder storage

Milk powder is a very common healthy drink. We often see people making milk powder to drink. Milk powder tastes sweet and delicious. It is a very favorite drink for many people. It is also rich in nutrients and has many benefits for our body.

Infant formula is not sterile. If the formula is not consumed within three weeks (21 days) after opening, it can only be stored for a month at most, because the nutrients in the formula are lost after a month. If it is more than 21 days old, but less than 60 days old, adults can eat it, but it is best not to eat it if it has been opened for more than two months.

Myth 1: The refrigerator can keep food fresh

Some mothers believe that refrigerators can preserve milk powder very well, so they put the unopened milk powder they bought in the refrigerator. The milk powder is put in and taken out of the refrigerator again and again. The temperature and humidity differences inside and outside the refrigerator can easily cause the milk powder to deliquesce, clump and deteriorate. In fact, as long as the milk powder is within the shelf life, it is more conducive to the preservation of milk powder at room temperature.

Myth 2: Store milk powder in transparent glass jars

Milk powder should be kept away from light, because light will destroy the vitamins and other nutrients in the milk powder. If some mothers like to use transparent glass jars to store milk powder, they can stick light-shielding paper on the outside.

Myth 3: Milk powder is placed in a humid environment such as the kitchen or near the refrigerator

Being in a humid environment for a long time is not conducive to the preservation of milk powder, and the iron cans of canned milk powder are also prone to rust in moisture.

Myth 4: The milk powder cap is not tight and not sealed

If the milk powder is not tightly covered and sealed, it is prone to oxidation, deterioration, moisture and other problems.

1. Canning and sealing

Compared with other packaging, canned milk powder has better sealing performance. After opening, the milk powder can be stored at room temperature, away from light, in a dry and cool place, and should be consumed within one month. Do not store the milk powder in the refrigerator. After scooping out the milk powder each time, be sure to close the lid of the milk powder can tightly.

2. Bag sealing

After opening the bagged milk powder, the bag mouth should be tied tightly. For easy storage and taking out of the milk powder, after opening the bagged milk powder, it is best to store it in a clean milk powder can. Before using the milk powder can, wipe it with a clean and dry cotton towel, do not wash it with water. After opening the milk powder, follow the regulations on the use time and consume it within about half a month.

3. Sealed in box

Boxed milk powder is usually packed in bags inside paper boxes. Its sealing convenience is not as good as that of canned milk powder. For the storage of boxed milk powder after opening, you can use the storage method of bagged milk powder. After opening, tie the bag tightly or put it in a clean milk powder can and consume it within half a month.

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

2. For canned milk powder, be sure to cover the plastic cover tightly after opening the can. For bagged milk powder, tie the bag tightly after each use.

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 use time of milk powder after opening. Most infant formula milk powder packaging clearly stipulates that milk powder should be used up within one month after opening. After opening, it should be discarded after more than one month. It is worth reminding that the expiration date on the milk powder packaging is the date when it is unopened and stored in appropriate conditions. Once opened, this date cannot be used.

4. Milk powder may clump within the specified use date. Normal milk powder should be loose and soft. After opening, the milk powder may absorb moisture due to moisture in the air or a small amount of water droplets inevitably introduced during the preparation of the milk powder, which may cause the milk powder to absorb moisture and easily clump. If the clumps break when squeezed, the quality of this milk powder has not changed 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.
