What s going on with the milk powder flushing up and foaming

Hello, because the milk powder is made of fresh liquid milk and wet blending to ensure the freshness of the milk powder, it is easy to produce foam. Excessive air bubbles are generated when preparing milk powder, mainly due to improper shaking up and down, or excessive shaking force. Foam is a physical phenomenon, milk powder dissolved in water can produce a stable colloidal solution, due to the surface tension and viscosity of the solution, stirring or brewing will produce long-lasting foam.

When the varieties of milk powder are different, their composition is different, the viscosity and surface tension of the colloidal solution are different, when the surface tension and viscosity are larger, the foam formed is more and larger, and the duration is longer, and vice versa. On the other hand, the foam produced by milk powder preparation is related to many factors such as the temperature of the water, the texture, shape, smoothness of the container, and the strength of stirring or vibration, so there will also be different foams formed. In fact, it is very easy to do without bubbles, that is, to add defoamer or physical treatment.

However, chemicals such as defoamers are not allowed to be added to infant formula. Different preparation methods of the same can of milk powder will have different foaming degrees, which will not affect the quality of milk powder.

If the milk powder is easy to burst out of the foam, it is common to see the milk powder clumping and hanging on the wall. This should be the reason why the milk powder is not soluble well. There is no skill in making milk powder, it should be the problem of the milk powder itself.

Moreover, the baby's stomach is very small, and if you drink too much milk foam and air ingress, it will burp and easily cause spitting up.

Among the milk powder I have tried at home, Xi'anzhi's dissolving effect is the best, 40 degrees of water, a little shake of the bottle, it is fully dissolved, no foam. The baby does not drink the milk compartment.

It is normal for milk powder to have foam when it is washed out, due to the surface tension and viscosity of the solution, more or less foam will be produced when stirring or brewing, and the main reason for producing more foam is that milk powder is rich in protein, and milk powder contains inorganic salts and acid ions.

Guidance: It is recommended to pour water slowly along the wall of the bottle when brewing, and the foam of the milk powder will be relatively less when shaking left and right.

Milk powder is rich in protein, and the protein activity is too strong in the stirring process is easy to foam, in addition to the milk powder brewing foam, it may be related to temperature, stirring strength, pressure, etc., can not be generalized, but inferior milk powder will also cause a lot of foam after brewing.

Why is there a lot of foam in brewed milk powder?

It is normal for milk powder to rush up a lot of foam, not all of it is due to the poor milk powder, just like if the egg will produce a lot of foam, the milk powder is rich in protein, the stronger the activity of the protein, the easier it is to foam during the stirring process.

Milk powder also contains inorganic salts and acid ions, which are also easy to produce foam after stirring, and the foam produced when milk powder is brewed, which has a certain relationship with the water temperature, the texture, shape, smoothness and stirring strength of the container.

After the milk powder evaporates from the water, the coarse particles of the milk powder inside will form more capillaries, and due to the dissolution of the milk powder during the brewing process, the bubbles in the small pores will be affected by temperature and pressure and float up, forming foam.

How to identify the quality of milk powder

Of course, poor quality milk powder will also foam during the brewing process, so we must be careful when buying. Normal milk powder has a strong aroma, if there is a clear nuclear mildew smell, sour taste, etc., most of them are deteriorated, and the good milk powder is milky yellow, and the inferior milk powder looks carefully, it will have crystallization and luster, and the color is also bleached, burnt yellow, etc.

Everyone should know that there is air in the foam, and eating too much will have a certain impact on the body. However, there are often a lot of bubbles when brewing milk powder, which makes the baby particularly uncomfortable and crying. So do you know what happens when there is foam in the preparation of milk powder?

Usually, there will be foam after the infant formula is foamed, mainly because the whey protein is added to the milk powder, and the higher the content, the more foam. The function of whey protein is that it is easily absorbed by the baby, making the baby strong, but one of its characteristics is that it is easy to foam when brewing. Some milk powder will add defoamer, so there is no foam or very little, usually foaming milk powder is not added with defoamer.

Solution: After shaking the bottle, it is recommended to leave it for a few minutes so that there will be less foam. And when preparing milk powder, you can draw a circle in one direction to shake the bottle, do not shake it up and down violently, so that the foam will be less, parents do not have to worry too much, the baby is fine to drink the foam, but it is necessary to prevent the baby from choking on bubbles.

Due to the surface tension and viscosity of the milk powder solution, foam will be more or less produced when stirred or blended. Protein (whey protein), an indispensable nutrient in milk powder, the fresher the milk powder, the stronger the protein activity and the easier it is to produce bubbles. When we usually stir eggs, we will also stir up a lot of bubbles, which is also because of the rich whey protein.

When preparing milk powder, if the temperature of the water is too high, the container containing the milk powder is not smooth enough, the shape is not regular enough, the stirring or shaking force is too strong, the direction is wrong, and the nipple hole is too large, bubbles will also be generated.

First of all, we know that the purpose of giving milk to the baby is to provide more nutrients for the baby to absorb, and giving the baby and goat milk powder has a role to a certain extent. Of course, breast milk is the best natural nutrition for babies, in addition to breastfeeding, mothers can consider giving their babies goat milk powder. As far as I know, goat milk powder has a high nutritional value, if you can't achieve breastfeeding, but for babies who are allergic to milk or milk powder, it is a good choice for Bao Ma to give her baby goat milk powder.

Secondly, giving the baby high-quality goat milk powder can help the baby better digest and absorb nutrients and enhance the baby's resistance. However, mothers also need to pay attention to the lack of vitamin B12 and folic acid in goat milk, and it is easy to cause megaloblastic anemia if it is given to the baby for a long time without complementary food. Therefore, it is recommended that mothers pay attention to whether vitamin B12 and folic acid are added to that milk powder when buying goat milk powder.

It is not bad for milk powder to foam when it is foamed, it is a normal phenomenon.

Because milk powder is processed from fresh liquid milk and wet mix, in order to ensure the freshness of milk powder, it is easy to produce foam. When the milk powder is brewed, it foams due to incorrect shaking up and down or excessive shaking force, which has no effect on the quality and nutritional content of the milk powder after brewing.

When the milk powder is of different varieties, the components contained in it will also be different, and the viscosity and surface tension of the colloidal solution formed will be different. Especially when the surface tension and viscosity are high, the foam formed is more and larger, and lasts for a long time, and vice versa.

In addition, the foam produced by milk powder preparation is related to many factors such as the temperature of the water, the shape, texture, and smoothness of the container, and the strength of the stirring vibration, so the foam formed may not be the same.

Precautions for brewing milk powder.

1. The amount of milk powder added is too much, and the concentration is too high. In this way, most parents are also in order to let the baby get more nutrition, so they will add more milk powder, but the concentration of milk powder is too high, so that the child's nutrients can not be absorbed, and the baby's stomach and intestines are damaged, and more serious ones will lead to stones in the child's stomach. Now most milk powder contains more sodium, and the baby's intake of too much sodium will also cause bleeding in the body, so it is okay to make milk powder in the future or according to the proportion.

2. The water temperature of soaking milk powder is too high. It's also winter now, so many parents like to make the water temperature higher when making milk powder for their children, so that when the baby drinks, it won't be too bright and upset. However, the normal water temperature is best around 50 degrees, if it is too high, it will hurt the baby's stomach, and the most important thing is to affect the secretion of the baby's digestive juices.

3. Rinse with purified water. Some parents will think that tap water is dirty and contains more heavy metals, so they will buy some pure water for their babies, thinking that it will be very clean, but there are not many elements in the bottled mineral water, although it is very clean, but it is indeed too clean. As long as the tap water is boiled, it is no problem to give it to your baby.

4. Some parents like to shake the bottle before giving their baby milk powder. In this way, there will be a lot of milk foam, these milk foams are still harmful to the baby's body, because the milk foam into the baby's body, will produce flatulence, for a long time, the baby's stomach is not good. Therefore, before giving the baby milk powder, it is best not to shake the milk foam, and stir it in advance.

It is not bad for the milk powder to bubble up. There is a lot of foam in the prepared formula, because the protein and nutrient content in the milk powder is relatively high, which leads to more foaming. In the process of preparing milk powder, if the preparation method is improper, the milk is not stirred in one direction, or the force is too strong in the process of stirring, resulting in excessive oscillation, it will also lead to more bubbles.

If no defoamer is added to the powder.

The water temperature when preparing milk powder is not well controlled, and too high a temperature can easily lead to bubbles. If the inner wall of the container used in the preparation of milk powder is not smooth enough, it is easy to foam if it is subjected to excessive oscillation during the preparation process.

Precautions for milk powderFeeding should be based on small and frequent meals, and do not feed too much at one time, so as not to cause indigestion.

When the baby has hiccups, you should not be fed milk powder, so that the gas is difficult to expel it.

Do not change the brand of milk powder frequently, and pay attention to hygiene and cleanliness when making milk powder, so as not to cause diarrhea due to unclean food for the baby. The baby is now relatively small, and the body's resistance is not as good as that of adults, so more attention should be paid to good care.
