How long can baby milk powder be kept after opening?

Baby milk powder shelf life

Baby milk powder shelf life is one of the mandatory product information in milk powder, and the product must maintain its unique quality during the shelf life. According to the provisions of the Food Safety Law (GB 7718-2004): If the shelf life or shelf life of a food is related to storage conditions, the specific storage conditions of the food should be indicated.

How long milk powder shelf life

Each brand of milk powder products on the market has a different shelf life. Most of them are in 18 or 24 months, the longest even up to 3 years. Experts pointed out that milk powder shelf life is usually not more than 2 years, the more important for milk powder is the opening period of use, as soon as possible, such as 400 grams of milk powder is best eaten within two weeks after opening, 900 grams of food within a month , And to be sealed.

Baby milk shelf life knowledge:

Milk powder packaging will indicate the shelf life, but it is best to eat milk powder that has been opened within one month, because after one month, some nutrients in milk powder will be lost, including DHA.

Improper storage of infant formula milk perishable

The biggest difference between infant formula and adult formula is that it is rich in nutrients and high in protein. Rich protein and nutrients are a breeding ground for bacteria to grow and reproduce. In order to avoid the pollution and deterioration of milk powder, in the preservation and preparation of infant formula milk powder after unsealing, attention should be paid to the following points regarding knowledge of shelf life.

Milk powder after opening

1. Milk powder should not be stored in the refrigerator after opening. The powdered milk is placed in the refrigerator and taken in and out again and again. The difference in temperature and humidity between the inside and outside of the refrigerator can easily cause deliquescence, agglomeration and deterioration of the powdered milk. Kaifeng's milk powder is usually stored at room temperature, protected from light, dry and cool.

2. Canned milk powder, be sure to close the plastic cover after opening the can. Bagged milk should be tied tightly after each use. To facilitate storage and removal of milk powder, bagged milk powder should be stored in a clean milk powder tank after unsealing. Use a clean, dry cotton towel before using the milk powder tank. Do not wash it with water.

3. The use time of milk powder after opening is stipulated. Most infant formula formulas have clear provisions, and milk powder should be used within one month after opening. After being opened, more than one month later, it should be discarded. It is worth reminding that the shelf life date on milk powder packaging is the date when it was unopened and suitable storage conditions. Once opened, this date cannot be used.

4. Milk powder may also cake during the specified use date. Normal milk powder should be loose and soft. After opening the milk powder may be due to the moisture in the air, or in the milk powder preparation process, it will inevitably bring in a small amount of water droplets and other reasons, so that moisture-absorbing milk powder, prone to caking. If agglomerated and broken, the quality of this milk powder does not change much. However, agglomerates that are large, hard and unbreakable indicate that the quality of milk powder is not good enough and should be abandoned.

5. Place sugar cubes in the milk powder tank to prevent moisture. Sugar cubes have the effect of absorbing moisture. After each use, the jars are sealed so that the milk powder is not susceptible to moisture.

6, when rushed milk powder, hands should be dry, to avoid wet hand drops into milk powder, this can ensure that the milk powder to save longer.

7. If the milk powder smells like a fish sauce, it means that the milk powder is already deteriorating. It should be discarded decisively and cannot be eaten by the baby.

How to modulate milk powder?

1. As far as possible with the current use. For convenience, bottles of milk can also be dispensed at one time, but be sure to place the reconstituted milk powder in the fridge immediately after adding the lid. Good milk should be used within 24 hours.

2. Drink the remaining milk, if the remaining amount is less, it is better to drain, if the remaining amount is more, can be stored in the refrigerator, but can not be stored for too long, it is best to drain within 1 hour.

3. The milk removed from the refrigerator should be thoroughly heated before drinking. Do not use hot milk in the microwave oven to prevent local overheated milk from scalding the baby's mouth.

In addition, when formulating powdered milk, keep your hands dry and avoid putting drops of water into the milk powder. This will ensure that the milk powder is kept longer. Unopened milk powder should be stored according to normal storage methods.

The packaging bags of milk powder need to be targeted at the nature of milk powder, with the following functions: long shelf life, fragrance preservation, oxidation and metamorphism prevention, moisture absorption and agglomeration prevention. Therefore the material we will be used for this feature is BOPP/VMPET/PE. 

1.  The composite material of BOPP meets the requirements of the milk powder, good printing and strength

2.  VMPET has good light resistance, good light resistance and good ductility. It has metallic luster. 

3.  PE has good anti-pollution sealing and low temperature heat sealing. 

4.  Aluminum foil with good moisture, rust, gas, light and corrosion resistance, its stiffness, mechanical strength moderate, good malleability, easy to process, can be made with paper, plastic composite, high temperature resistance aluminum plastic composite materials, suitable for high temperature sterilization packaging, vacuum packaging. The use of aluminum foil composite materials can effectively improve the shelf life of products; resist oil to the packaging of infiltration dyeing.
