How long is the shelf life of milk powder?

Things like milk powder can generally be stored for a long time if they are not opened, usually 18 months or 24 months. When buying milk powder, we must check the production date and shelf life. This is something we need to pay attention to when buying any kind of food. The shelf life of milk powder will become shorter after it is opened, and everyone should pay attention that milk powder should be placed in a dry environment, not in a humid environment, as it will absorb water.

What is the shelf life of formula milk?

The shelf life of various brands of milk powder products on the market varies. Most are within 18 or 24 months, with the longest being 3 years. Experts point out that the shelf life of milk powder should not usually exceed 2 years. What is more important for milk powder is the shelf life after opening. It should be consumed as soon as possible. For example, 400 grams of milk powder should be consumed within two weeks after opening, and 900 grams should be consumed within one month, and it should be stored in a sealed container.

It is understood that the milk powder currently sold in the domestic market has a labeling time of basically two years for both domestic and foreign products. As early as a few years ago, the shelf life of domestic milk powder was marked as one year, while the shelf life of foreign milk powder was two years. Later, as domestic milk powder continued to catch up with foreign milk powder, it also began to be marked with two years. Taking into account the freshness and degree of oxidation of milk powder, industry experts believe that a one-year shelf life is more scientific and the quality of milk powder is better. However, there has always been controversy over how long the shelf life is.

Whether it is imported milk powder or domestic milk powder, a considerable portion of the packaging is unqualified, including one or two soft packages and most cans. Although it has always been believed that the canning seal is effective, the test results are surprising. The survey mentioned that milk powder is easily affected by moisture after being oxidized, and it is easy for oxygen and water to enter the powder and form powder clumps. Such milk powder is easy to deteriorate and easily produce aflatoxin. This is also the reason why many milk powders receive complaints from consumers. If the oxidation rate is too high, the food will oxidize and deteriorate after four to five months and will be inedible. All products tested at that time were within their shelf life, and many of them even had a shelf life of less than one year.

How to store milk powder after opening the lid

Because infant formula is rich in nutrients and high in protein, the rich protein and nutrients are a breeding ground for bacterial growth and reproduction, and it is also easy to attract insects. Consumers must be careful to preserve the milk powder after opening it.

1. Do not store in the refrigerator after opening. Because of repeated taking out and putting in, the temperature and humidity differences inside and outside the refrigerator can easily cause baby milk powder to deliquesce, clump and deteriorate.

2. After opening, milk powder can usually be stored at room temperature, away from light, in a dry and cool place. After each use, be sure to cover the plastic lid of the canned milk powder tightly and tie the bag tightly.

3. 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, dry cotton towel before use, and do not wash it with water.

4. After opening the milk powder, the use-by-time regulations must be followed. Most baby 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.

5. Put sugar cubes in the milk powder can to prevent moisture. Sugar cubes have the effect of absorbing moisture. After each use, the jar should be sealed so that the milk powder will not be easily affected by moisture.
