After the milk powder is opened, will it expire if it is not eaten for a month?

After the milk powder is opened, it needs to be drunk within a month, and it takes a long time If it is not stored properly, it may deteriorate due to moisture, and the milk powder needs to be drunk in time after it is brewed, and if it is more than an hour, don't drink it, especially in summer, the temperature is high, and the nutritional value of milk powder is also high, and it is easy to breed bacteria and deteriorate, so you can feed the baby with a small number of meals, so as to avoid drinking more than an hour later, you can not drink it again.

The shelf life is not equal to the last before time, and after the expiration date, its quality may deteriorate to some extent. Due to the long storage time, the flavor and texture have undergone some changes, the taste is not fresh, the vitamin content has also decreased, and the fat may be slightly oxidized. Because even within the expiration date of food may shorten the shelf life due to improper packaging or storage, everyone should pay special attention.

Expired food may also undergo chemical changes when it is infected by bacteria, producing nitrosamines, acrylamide and other substances, resulting in chemical poisoning, inducing cancer, cardiovascular diseases and even genetic mutations.

How to store unopened milk powder:

1. Room temperature. Some people think that the refrigerator will keep it fresh, so they store the unopened milk powder they bought in the refrigerator. 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.

2. Protect from light. Milk powder should be kept away from light, because light can destroy the vitamins and other nutrients in milk powder. If some mothers like to use transparent and beautiful glass jars to divide milk powder, then they need to put blackout paper on the outside.

3. Drying. Although unopened milk powder is sealed and generally not susceptible to moisture, long-term exposure to humidity is not conducive to the preservation of milk powder, and canned milk powder cans are also prone to rust in moisture.

4. Cool. The thermal stability of some nutrients in milk powder is poor, such as vitamins, and long-term storage at high temperatures will affect the quality of milk powder, so special attention should be paid to storing milk powder in a cool place.

Infant milk powder is an important nutrient for the baby's health**, now there are many types of milk powder on the market, many parents will buy a milk powder suitable for the baby, about the storage and shelf life of the milk powder.

A lot of novice parents.

I don't know much about it, so can I still drink milk powder if I open the can for 3 months without getting wet? Let's take a look at it with the questions.

Milk powder can be opened for three months, although there is no dampness, but it is also not allowed to drink, because the shelf life of milk powder after opening is only one month, and the milk powder after opening will continue to be in contact with the air, which will breed a large number of bacteria.

situation. And three months after the milk powder is opened, the nutrients may be lost, so it is recommended that the milk powder should be eaten within a month once the can is opened, and it must be protected from light when preserved, and placed in a relatively cool environment. It is necessary to pay attention to the fact that the milk powder cannot be stored in the refrigerator to avoid the deterioration of the milk powder.

Remind parents that if the milk powder has been opened for a month and has not been eaten, it is not recommended to eat it at this time, and the baby's stomach is relatively weak, if you drink these milk powder, it will cause harm to the stomach.

Unopened milk powder expires for 2 months, and it is necessary to judge whether it can be eaten according to the condition of the milk powder. Milk powder due to the lack of water, its shelf life is generally long, if the expiration time is not long, and there is no dark color, impurities or foreign bodies can be seen with the naked eye, and there is no stale smell, musty smell, hala smell, etc., you can also eat.

The shelf life of a food is the period during which the food maintains its quality under the indicated storage conditions. The shelf life is determined by the manufacturer according to the characteristics of the food produced, accelerated experiments or test results, which is equivalent to the commitment given by the company to consumers for the product - within this period, the flavor, texture, and safety of the food are all the best, and you can eat it with confidence.

No, you cannot. The milk powder has expired for 2 months, and if it expires for a year, the milk powder has basically deteriorated, and the milk powder that has expired for one year smells abnormal and the powder is agglomerate. Spoiled milk, whether it is drunk by infants or adults, can easily lead to gastrointestinal problems, especially the gastrointestinal function of infants and young children is relatively weak, so the milk powder cannot be drunk if it has expired for one year.

Precautions: For the sake of physical health, it is recommended not to drink expired milk powder at ordinary times, and at the same time, do not buy too much at one time when buying milk powder.

Milk powder should be drunk within a month after opening the can, and it can be drunk for more than a month. Reason: Because the sugar content of baby milk powder is relatively high, the particles are fine, and it is easy to regurgitate after opening, so you should try to eat it within a month.

Don't put the open baby milk powder in the refrigerator, because the refrigerator is a closed, humid environment, baby milk powder is very easy to absorb moisture and clump in the room, accelerating the qualitative change. When the milk powder can is opened, it carries the air with germs, oxygen and water vapor molecules. Even if the lid is closed again, the milk powder can may be filled with a large number of germs, oxygen and water vapor molecules.

After the infant formula is exposed to environmental contamination by bacteria and oxygen and water vapor molecules, a lot of nutrients are leaked out. After the milk powder can is opened, even if it is drunk for a week, the milk powder will lose more than 10-15% of nutrients, and more than 20-30% of nutrients will be lost in 2-3 weeks.

When the milk powder can is opened, store in a cool, dry place. For canned milk powder, try to close the plastic bottle cap tightly after each opening and use. If you take it every time you take it and close it on the contrary, the baby milk powder can seal the lid and can be stored for a long time.

The bagged milk powder should be firmly sealed after each use and stored at room temperature. In order to facilitate storage and access, after the bag of milk powder is opened, it is best to store it in a clean milk powder can, and scrub the milk powder can with a clean and dry cotton towel when using it, and do not wash it with water to prevent corrosion. If you use glassware, it is best to have colored glass, never transparent bottles.

Since infant milk powder should be stored away from light, the light source will destroy the vitamins and other nutrients in the milk powder.

How to identify high-quality milk powder: Look at the hue of the milk powder, and the difference in color can be very obvious. It should be noted that the color of baby milk powder is not too yellow or too white, and yellow-brown ones like this will be better.

Compared with infant milk powder, if the baby milk powder is not clumpy, the texture is loose, and the particles are evenly proportioned, it can be said to be a good milk powder. If the milk powder is lumpy, it may be caused by the poor sealing of the baby milk powder, or it may be that the baby milk powder itself is relatively clammy and cold. Dry baby milk powder is good for storage after opening the can, and if the baby milk itself is clammy and cold, it is very easy to clump after opening the can.

If the baby formula is very easy to clump and there are more particles in the hand, it means that it is more clammy and cold.

Because these milk powders are vacuum-packed, the shelf life is a certain period, although the time is very long, but it will affect the taste and quality will also add some bacteria, more than a month can still be drunk, but try to drink it all.

Under normal circumstances, the milk powder must be drunk within a month after the lid is opened, and if the milk powder is not finished for a long time, it is easy to deteriorate. In general, there are no additives in milk powder, so you should drink it as soon as possible after opening.

The milk powder can't be eaten for a month after the canning has been opened.

Reasons: 1. You should know that the milk powder can is in a vacuum state before it is opened, and the milk powder can keep it fresh.

2. However, once the can is opened, the air carrying bacteria, oxygen and water vapor molecules will take advantage of the void to enter, the environment and air humidity in the milk powder can will change, and the active substances and nutrients in the milk powder will begin to gradually lose.

Therefore, after one month of opening, don't drink the milk powder anymore, it will cause physical discomfort. For milk powder, the more important draft is the expiration date after opening, consume as soon as possible, such as 400 grams of milk powder after opening and taking within two weeks, 900 grams of milk powder within one month, and to be sealed and preserved.
