Milk powder foams when brewing, why? What to do

Foam is produced after all milk powders are prepared, but the foam is different because of different formulas or batches. It is also normal for foam to occur after the bottle is shaken during preparation, which is related to the bulkiness and dryness of the milk powder and the solubility of the milk powder. This is especially true for infant formula, which may produce more foam after blending due to the higher content of whey protein.

Therefore, attention should be paid to the method when blending, and the foam can be appropriately reduced. When preparing milk powder, be sure to put boiling water at about 40 degrees first, and then put milk powder. After putting the powder in, let it sit for a short time, and after the powder sinks into the water, rotate the bottle with your wrist.

In this way, a large amount of foam is not generated.

The bubbles in the milk powder just indicate that it is a good milk powder.

Hello, there or no foam is a physical phenomenon, because the milk powder is made of fresh liquid milk and wet mix to ensure the freshness of the milk powder, so 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.

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.

The protein in milk powder is active, and the more active it is, the more bubbles it will have.

Milk powder is every baby's nutrition and a necessity for their growth. Many babies will continue to drink milk powder until they are three years old, so this period is quite long, which requires parents to choose a good milk powder for their babies, and also to master the correct way to bubble milk. However, making milk powder is also a technical job, and mastering the correct method of making milk powder is very important for every parent.

Reasons why there is milk foam in milk powder:

The first is that milk powder is already viscous, and when you stir too hard, it will produce more or less milk foam. The second is because there is a very important nutrient for the baby in the milk powder - protein, because the protein itself is active, so it is easy to produce bubbles. The third is that when making milk powder, milk foam may occur for various reasons, such as high water temperature.

Is it good or bad to have foam in the milk?

The answer is obvious. Of course it's not good. If your baby drinks milk with milk foam, he will inhale too much gas, causing him to leak milk.

Precautions for milk brewing:

1.Suitable water temperature. Please read the instructions carefully on the milk powder, it is clearly written that if the water temperature is too high, some nutrients may be killed.

2.Do not stir with chopsticks or other utensils. Don't worry about the milk powder not dissolving, just hold chopsticks or spoons and stick it in, so it will be easy to foam.

3.Dissolution is also a specialty. The correct way to make milk is to grasp the lower half of the bottle tightly with both hands, use even force, and rub it in the horizontal direction, not up and down. When rubbing the bottle, the force should not be too much, and the movement should be gentle, and the bubbles will be a little less.

In fact, it is normal to produce a small amount of bubbles in the process of brewing milk powder, but if the brewing method and utensils are not used properly, it will lead to a large amount of foam.

1. Appropriate water temperature.

Different brands of milk powder have different proportions, but generally speaking, it is better to use warm water at 40-60 degrees Celsius. This temperature is not only conducive to speeding up the speed of chemical reactions, promoting the dissolution of sugar, milk powder and other substances in the liquid, making a relatively uniform solution, but also ensuring that the nutrients in the milk powder are not destroyed. If the water temperature is too high, first, the milk powder will clump and cannot be fully dissolved; Second, it will cause clots in the whey protein in milk powder, affecting digestion and absorption.

2. Use mainstream milk bottles to make milk powder.

Generally, glass bottles and plastic bottles, it is best to regain the habit of using glass bottles, because glass bottles are easy to break, and they really can't find other shortcomings, the most safe, the key is to be smooth and clean, not to choose the corners and corners everywhere, strange-shaped bottles, before brewing milk powder, sterilize the bottles at high temperature.

3. Stir less with chopsticks.

Many novice parents like to use chopsticks or spoons to stir because they are afraid that the milk powder will not be dissolved, which is completely redundant, which may not only bring dust and bacteria into the milk powder, but also produce more foam.

Under normal circumstances, the water is received first and then the milk powder is put in, and there will be no foam when the lid is closed, and there will be foam when the bottle is shaken up and down.

Because milk powder is made of milk extracts, which also adds some other flavoring ingredients, so when you take it with boiling water, it is likely that there will be foam, which generally does not affect the drinking of milk powder, and it is basically harmless to the human body.
