Can I still drink milk powder if it is lumpy?

If the milk powder is lumpy, it cannot be drunk.

Milk powder clumping is divided into two situations, one is because the seal is not tight, the milk powder is damp, and the damp milk powder will have diarrhea after drinking it to the baby, so it cannot be given to the baby. Another situation is that the expired milk powder may also be clumped, and the expired milk powder has deteriorated and cannot be given to the baby.

Normal milk powder can not be drunk for a month after opening, and after one month, the milk powder may deteriorate or breed bacteria. The clumping of milk powder indicates that the milk powder has deteriorated, and the spoiled milk powder has no nutritional value, and the baby will drink the spoiled milk powder, which will cause gastrointestinal discomfort or other diseases. So for the sake of your baby's health, don't give your baby clumps of milk powder.

In the past two years, everyone has developed the habit of buying more things in case of emergency, and after a fierce operation, various "...... have appeared in the circle of friendsCan you eat it?" With the arrival of the rainy season, there is a new question in the "Can You Eat" series: can the milk powder be clumped, can it still be drunk?

Only agglomerated by moisture

Milk powder is drinkable

The most common cause of clumping in milk powder is "moisture". Milk powder is a very dry powder, which is very easy to absorb moisture, if the air humidity is high, and the milk powder packaging is damaged, the opening time is long, or it is not properly sealed, etc., it is easy to get wet and agglomerate.

There are also some damp clumps that are the result of "good intentions doing bad things". For example, if you are worried about the spoilage of milk powder in summer, put it in the refrigerator for storage. As a result, the temperature difference caused condensation to form on the inner wall of the milk powder can.

If the milk powder is only wet and agglomerate, and the spoon can touch it open, it can actually be eaten with confidence, without affecting nutrition and absorption, but it may not be so easy to dissolve.

However, if the lumps are hard and need to be crushed vigorously to crumble, it is recommended not to eat them again because there may be a risk of microbial contamination.

To avoid clumping, there are three things to pay attention to

If you want to avoid moisture and agglomeration of milk powder as much as possible, it is recommended to start with the following points:

1.Before opening the milk powder, carefully check the appearance to make sure that there are no damages, cracks, dents, or other conditions that could cause air leakage. If so, contact the seller or manufacturer in time.

2.After opening, store the milk powder in a cool, dry place as much as possible. In addition, regardless of whether it is opened or not, do not put milk powder in the refrigerator, as it cannot be "fresh" in the refrigerator, but it may "moisturize".

3.Seal the milk powder as soon as possible after taking it, and if the milk powder spoon is wet, wipe it dry and dry it before using it (by the way, it is best not to throw the milk powder spoon in the milk powder can, find a clean place to put it).

In some cases

It is a pseudolumpy

Sometimes it is clearly a well-packaged and newly opened milk powder, but when you open it, you find that there are some small pieces inside, and the milk powder falls apart with a gentle pluck with a spoon or chopsticks.

This is called "pseudolumping", and there are two general causes:

One is the electrostatic adsorption caused by the friction of milk powder particles due to vibration and collision during transportation and storage;

The other is because it has been left for a long time, such as being on the shelf without moving. Pseudo-clumped milk powder is even less tangled and can be eaten safely.

Of course, in the end, there is a reason for the clumping of milk powder, that is, the milk powder attracts small insects after it is opened. If consumers do find live insects in the milk powder, it is very likely to be caused by improper storage, such as damaged outer packaging, unclosed lids, unsealed bags, and small insects sneaking in while you are not paying attention during the process of picking and disposing.

In the process of brewing milk powder, there is also a situation of "lumping". However, this kind of "lumping" is often not the lumping of the milk powder itself, but the wrong method of preparation.

The correct way is to add warm boiled water of about 40 degrees to the bottle first, then put the milk powder in proportion, and then shake the bottle, which can basically solve the problem of difficult to flush.

Wen Zhongkai (Director of Kexin Food and Health Information Exchange Center).

The milk powder is lumpy, some can drink, some can't.

If the milk powder has a small lump and breaks it with a light touch of the milk powder spoon, there is no problem with this quality and you can eat it. After the milk powder is clumped, first look at whether the milk powder has changed color and taste, if there is no change, then look at the size and hardness of the clumps, if you press or touch it with a milk spoon, it can be loosened, this is a normal phenomenon, you can continue to eat.

Caking is due to the friction of powdered items during transportation, the gap between the particles becomes smaller, and static electricity is generated between the milk powder particles, which forms loose clumps and adherence or slight agglomeration with vibration, but it does not affect the quality of milk powder products. However, if the milk powder is very lumpy and difficult to crush, it has deteriorated, and this situation is not edible.

How to store milk powder

If it is a canned milk powder, it is recommended to eat it within one month after opening, and if it is a sealed milk powder in the form of a belt, it is recommended to eat it within half a month after opening the bag. There are several points to note in the preservation of milk powder, one is to store the nuclear residue cover at room temperature, and never put it in the refrigerator, because the humidity in the refrigerator is relatively high, and the milk powder is easy to clump or breed bacteria.

The second is that the milk powder must be kept away from light, and the third is that the dry milk powder should be stored in a dry and ventilated place. Fourth, the thermal stability of some nutrients in the cool milk powder is relatively poor, and the fifth is that the clean milk powder should be placed in a clean, pollution-free place, and should not be put together with easily polluted items. Expired milk powder may also be a phenomenon of clumping, so you must not give it to your child.

When the milk powder is damp and clumpy, it is not recommended to continue drinking.

Because milk powder is normally soft and loose, the reason why there is a caking phenomenon may be caused by moisture absorption, and this kind of milk powder is unsafe. If the milk powder itself contains a certain amount of water, and during transportation or handling, it causes water molecules to collide and aggregate to produce agglomeration, but the agglomeration is easy to disperse after shaking again, as long as it is a regular brand and within the shelf life of the milk powder, it will generally not affect the use.

Generally speaking, milk powder is very hard after clumping, and it is not easy to crush, which means that the quality of milk powder is not good. If the milk powder is lumpy, it can be easily crushed, and it usually does not affect the normal consumption of the milk powder.

How to store milk powder

1. Before opening: Before opening in a dry, cool and dark place, the air will not enter the milk powder, so the milk powder is not easy to deteriorate. At this time, just store the milk powder in a dry, cool and dark place.

The main reason for choosing such an environment for storage is to avoid the milk powder cans from rusting in a humid environment.

2. When brewing: there are two ways to wash hands and milk powder contaminated with bacteria and microorganisms, one is the mother's hand, and the other is the preparation table. Therefore, mothers should ensure environmental and hand hygiene when preparing milk powder, first clean the preparation table, and then rinse their hands with warm water.

3. After preparation: The packaging of squeezed air vacuum sealed milk powder is mainly divided into cans, bags and boxes. The three kinds of packaging silver branches are matched in vertical ratio, the canned sealing is the best, as long as the lid of the milk powder can is tightly closed after opening, the milk powder is not easy to deteriorate.

For sachet milk powder, the air in the bag should be squeezed out by hand first, and then the seal should be clamped tightly with a clip. Boxed milk powder is more cumbersome to store, and it is better to pour the milk powder into a milk powder can for preservation.

The milk powder is clumped and cannot be drunk.

Milk powder is usually made from goat's milk or cow's milk, which is rich in nutritional value, containing a lot of protein, vitamins, minerals, etc., and the calcium content is also relatively high.

However, if the milk powder is stored in an abnormal way or placed for a long time, it will lead to the deterioration of the milk powder, and the milk powder will clump after deterioration, and there will be a large number of bacteria, viruses and aflatoxins in the local multiplication, so it can not be eaten. No food should be eaten as long as it has gone bad.

Precautions for the purchase of milk powder:

Clause. First, when choosing high-quality formula milk powder, first look at the milk source.

The quality of the milk source directly determines the quality of the milk powder, and there are two main factors that determine the quality of the milk source: one is the natural environment; The second is the quality and supervision of milk sources. The world's recognized good milk source belt is the first milk source belt in the Netherlands.

Clause. 2. When parents buy milk powder, they must not blindly follow the trend, and pay attention to both nutrition and absorption, the most important of which is the rationality of the nutritional ratio of formula milk powder. When purchasing, you can check the nutrition label on the outer packaging of milk powder.

What is included in the nutrition label, how much nutrients are provided, and what percentage is enough for a certain age group to meet in a day. For example, how much protein is provided per 100 grams, whether DHA is added, whether the product can provide the nutrients your baby needs, etc.

Clause. 3. When purchasing milk powder, you need to pay attention to the taste.

Children love to drink is the last word, if children don't like to drink, no matter how high-end milk powder is, it is useless. Therefore, taste is also an important criterion for selection.

Clause. Fourth, distinguish different versions of imported milk powder.

When it comes to high-end milk powder, the first thing that comes to our mind is definitely imported milk powder. In fact, consumers may not know that there are also three versions of imported milk powder. The first is the "domestic version": that is, it sets up factories in China to process milk powder produced from foreign milk sources.

The second is the "parallel version": milk powder bought through certain channels that is only sold in other countries and regions such as Europe and the United States, such products often do not have a single Chinese on the packaging, and are designed for the constitution and needs of foreign babies, and may not be suitable for Chinese babies, which is what we often call "parallel goods".

The third is the "original imported version": that is, the milk powder is completed in foreign countries from the milk source to the packaging, and is designed for the physique and needs of Chinese babies, which is the real original imported milk powder recognized by our country.

It is best not to drink clumps of milk powder, depending on the situation.

If the milk powder is dry, delicate and powdery under normal conditions, when the outer packaging is opened, the milk powder is in a vacuum environment, and there will generally be no clumping during the shelf life. The outer packaging is open for a short period of time, and it will fall apart when patted with a spoon, usually because the milk powder has absorbed the moisture in the air, and the quality of the milk powder has not changed, and it can be drunk.

There is a large area of clumping in milk powder, and the clumped milk powder cannot be loosened by external force, so it is not recommended to drink. Under normal circumstances, it is recommended to drink the milk powder within a week after opening, and the milk powder absorbs a lot of water for a long time, and there may be a large area of agglomeration, and the protein in the milk powder at this time may be denatured, the oxidizable components may have been oxidized, the volatile nutrients have been volatilized, and the nutrients in the milk powder have been greatly lost, so it is not recommended to drink.

Precautions

Some milk powder clumps are because they are not sealed and stored well after drinking milk powder, and there is air leakage, which will cause the milk powder to clump, so parents must pay more attention to the milk powder seal in the future, so as not to recur this situation. If the clumped milk powder has not expired, adults can wash their faces and feet vigorously, and the effect is similar to that of milk, so there are still many uses.

Generally, milk powder is very loose and soft, and infant milk powder must be drunk within the time stated in the product manual after opening, and there should be a sealed cover, which should be stored in a dry place and not damp. It is not recommended to put the opened milk powder in the refrigerator, because if it is placed in the refrigerator, it is easy to absorb the moisture in the refrigerator, it is easy to form clumps, and it is easy to carry over the flavor.
