Why can't milk powder be mixed and there are lumps? How to mix milk powder without lumps?

Milk powder is a necessary substance to supplement the baby's body with nutrition and protein. Many mothers find that they cannot make the milk powder, and the milk powder is full of small lumps that cannot be dissolved. What's going on? The editor will tell you the reason.

1. The size of milk powder particles is not ideal. If the milk powder particles are too large, they are easy to infiltrate and settle, but difficult to disperse and dissolve. On the contrary, if the milk powder particles are too small, they are easy to float, which is not conducive to infiltration and sedimentation. In addition, the capillaries inside the fine-grained milk powder particles are relatively thin. When they come into contact with water, they easily form a liquid film to block the capillary opening, making it impossible for water to penetrate and diffuse. This is also not conducive to infiltration and sedimentation, and ultimately leads to the appearance of "lumps".

2. The fat content in milk powder is too high. Milk powder contains about 20%-25% fat. Fat is hydrophobic. Too high a fat content will hinder the infiltration process of milk powder, and then affect the sedimentation, dispersion, and dissolution of milk powder particles, which will greatly reduce the solubility of milk powder. Therefore, under the same mixing conditions, skim milk powder is generally better than whole milk powder.

3 The water content of milk powder increases. The freshly opened milk powder has better mixing properties, but after a period of time, the milk powder may become damp and the water content increases, which reduces the wettability of the milk powder and reduces the mixing effect of the milk powder.

4 The protein in milk powder denatures. The protein content in milk powder is about 20%. If you use water with too high a temperature to mix milk powder, it will easily cause the protein to denature and coagulate. The coagulated protein makes it impossible for the milk powder particles to disperse and dissolve better.

1. Soak the bottle in hot water before making milk powder. The bottle must be soaked in hot water, because there will be some small water droplets in the bottle. If the bottle is not heated, then when the milk powder is poured into the bottle, the milk powder will turn into small lumps when it encounters these small water droplets. Then, if you pour hot water into it, it will be difficult to dissolve it no matter how much you shake it.

2 Use a small spoon to pour milk powder. When pouring milk powder into the bottle, do not pour it directly into the bottle, as it is very easy to spill and cause the milk powder to clump and form small lumps. If you use a spoon to pour milk powder, you can reduce the contact area between the milk powder and the bottle, so that no milk powder will remain on the bottle and turn it into hard lumps.

3. When mixing milk powder with warm water, do not use very hot water, as this will destroy the nutrients in the milk powder. Do not use too cold water either, as the milk powder will clump due to the low water temperature and will also affect the taste of the milk powder. Be sure to use warm water, which will not affect the taste, will not form lumps, and will not destroy the nutritional structure.

4. Shake while pouring water. When making milk powder, do not pour all the water in and then shake the bottle. After pouring in a little water, gently shake the bottle. This will allow the milk powder to fully dissolve without lumps and lumps, and will also fully dissolve the nutrients in the milk powder.

5 Rub the bottle with both hands. If you find some small lumps in the milk powder when you are making it, hold the bottle with both hands and rub it back and forth. This way, the lumps in the milk powder will dissolve quickly. Do not shake the bottle up and down or left and right, as this will produce bubbles.

The reason why there are lumps in the prepared milk is that the milk powder has not been completely dissolved. The main reason may be that the mother uses an improper mixing method, which results in poor dissolution of the milk powder. However, parents do not need to worry, even if there are incompletely dissolved milk lumps in the milk powder, it will not affect the normal nutritional content and consumption, so parents can still give it to their babies.

The correct way for mothers to prepare milk powder for babies is to first take out a sterilized milk bottle, then put in an appropriate amount of warm water according to the baby's appetite. The temperature should be controlled between 40 and 50 degrees for the best. Then, according to the mixing ratio of water to milk powder, add an appropriate amount of milk powder. Finally, cover the nipple and bottle cap, and shake the bottle left and right to dissolve the milk powder. After preparing, mothers should be careful not to feed the baby immediately. They should first test the temperature of the milk to avoid overheating the water, which may easily scald the baby's mouth and esophagus. At this time, mothers should drop a few drops of milk on the inside of their wrists. Generally, as long as the temperature is not hot, the baby can drink it. In addition, parents should remember that after the baby drinks milk powder, they should also pat the back to burp.
