Fan brother guide:
In winter, the temperature difference between morning and evening is large, the humidity is heavier, and some nutrients in milk powder are easily oxidized in the air, and once the milk powder is not stored properly, it will accelerate the deterioration of milk powder. Therefore, the storage of milk powder is not a simple matter of "covering it"!So how to store milk powder to be safer and more secure?Let's take a look at it today
01 Dangers of improper storage of milk powder.
1. Reduced nutritional value.
The milk powder that your baby drinks is very nutritious, including protein, fat, carbohydrates, vitamins and so on. However, these nutrients are not stable, especially after the milk powder is opened, it is particularly susceptible to humidity, temperature, light and other factors, and then chemical reactions such as fat oxidation, lactose crystallization, decomposition, and deterioration occur, reducing the nutritional value of milk powder.
2. Accelerate the deterioration of milk powder.
1) Microbial contamination.
The milk powder that the baby drinks is rich in nutrients, and the milk powder after opening the can is more likely to be exposed to external pollution, once it breeds bacteria, it will become a hotbed for bacterial growth and reproduction, and the nutrients in the milk powder are easy to be decomposed and destroyed, accelerating the deterioration of the milk powder.
2) The humidity is too high.
When the moisture absorption of milk powder rises to more than 5%, it is easy to have a chemical reaction, resulting in the deterioration of milk powder, which will also accelerate the deterioration of milk powder.
3) Sunlight exposure.
Direct sunlight may make milk powder affected by light and high temperature, and appear caking or deterioration, such as reducing the activity of vitamin C and vitamin B2, accelerating the oxidation of fatty acids, and affecting the nutritional value and taste of milk powder.
02 Wrong practices in milk powder storage.
1. Put the milk powder in the refrigerator.
In daily life, some mothers will think that storing milk powder in the refrigerator can keep the milk powder fresh and not easy to spoil, but this practice is not correct. The temperature difference between the refrigerator and the outside is large, and after the milk powder is opened, the sealing of the milk powder can is reduced, and some ingredients in the milk powder are easy to absorb moisture.
2. Not paying attention to the storage location, resulting in dampness or unhygiene.
Some parents will place the milk powder in a humid environment that is also easy to breed bacteria, which will increase the chance of spoilage or contamination, and the milk powder cans will also cause rust due to moisture.
3. Put the excess milk powder back into the can.
Some parents are not sure of the amount when they make milk powder, or they take the milk powder out but don't finish it, and the excess milk powder is not willing to throw it away and pour it back into the milk powder can. The milk powder will come into contact with feeding bottles and other utensils, and it is very susceptible to bacteria and moisture. If it is poured back into the can, it is likely to contaminate the milk powder in the original can or bring water in, which can cause moisture in the milk powder or cause cross-contamination that can be exploited by bacteria.
4. I didn't dry my hands when I took the milk powder.
Failure to wash your hands before making powdered milk, or not drying your hands after washing them, or dripping with dampness, may introduce microorganisms into the milk powder can. There are also milk powder cans with loose lids, which can also allow moisture or bacteria to enter.
03How to tell if the milk powder has deteriorated.
If the milk powder is stored wrong, it is easy to deteriorate, and if you want to know whether the milk powder has deteriorated, Bao Bao Bao Mom can judge through the following points:
1. Unopened milk powder.
Each can of milk powder is printed with the production date and expiration date, and it is important to confirm whether the milk powder is still within the expiration date before opening the can. In addition, you can also pick up the milk powder can, shake it from side to side, if you can hear the "rustle" sound, it means that the milk powder is fluffy and normal, and you can give it to the baby with peace of mind!If you hear a heavy "bang bang" sound, then it may be that the milk powder has clumped, in this case, it is not recommended to let the baby drink it again.
2. Milk powder that has been opened.
1) Pinch the powder.
Normal milk powder is loose and soft when pinched, and if the lumps are broken by hand, and there is no discoloration and taste, there is no deterioration;If it is sticky, hard, and not easy to crush when pinched by hand, it means that the milk powder has deteriorated and can no longer be eaten.
2) Smell the smell.
Normally, powdered milk powder smells faintly milky. If mothers smell mold and rot, it means that the milk powder has deteriorated.
3) Look at the brew.
If a large number of insoluble particles are produced when brewing milk powder, and the bottle body appears flocculent precipitation or stratification occurs after being stationary for five minutes, then the milk powder has deteriorated.
4) Taste.
Normal milk powder tastes faintly milky. If the milk powder has a sour, bitter, astringent and other peculiar smells, it means that the milk powder has deteriorated, and do not give it to the baby anymore.
04How to properly store milk powder in winter.
1. Milk powder needs to be placed at room temperature, dry and away from light to avoid affecting the quality of milk powder. In addition, the storage position of milk powder should be placed more than one meter above the ground, so that the milk powder is not easy to deteriorate.
2. Milk powder needs to be placed in a clean and hygienic place or an independent operating table, and the operating table should be kept clean and hygienic. Pay attention to keep your hands clean when taking milk powder, avoid bringing bacteria into the can, and seal and store the milk powder in time after taking the milk powder, so as to avoid the milk powder can being left open for a long time.
3. It is not recommended to transfer the milk powder to other containers after opening, or pour the excess milk powder into the tank again to avoid secondary pollution.
4. Before and after the milk powder is opened, the use time should be followed. Before opening, parents should pay attention to the production date and shelf life of milk powder, especially those who are accustomed to hoarding multiple cans of milk powder at one time. After opening, you should also pay attention to the expiration date, such as the milk powder is used up within 1 month or within 20 days after opening. In addition, it is also important to pay attention to the baby within the expiration date to avoid the deterioration of the milk powder.
Finally, Brother Fan also has a milk storage trick to tell everyone: after opening a can of milk powder, Bao Bao Mom can write the "opening time" with a marker pen on the milk powder can, so that it is convenient to pay attention to the "limited consumption time" of milk powder
