How long breast milk is stored, how long breast milk is stored

For babies, breast milk is a more natural and pure nutrient than milk powder. So how long does such precious breast milk last? The storage time of breast milk can be divided into room temperature storage time and refrigeration storage time, welcome to read this article to understand the storage time of breast milk.

Generally speaking, there are two kinds of breast milk preservation, one is that the mother works in the company, because the company does not have refrigeration equipment, and can only store breast milk at room temperature. The storage time of breast milk stored at room temperature is short, and mothers should pay attention to marking the time on the bottle where breast milk is stored to avoid the occurrence of digestive tract diseases caused by the baby drinking expired breast milk.

Colostrum (expressed within 6 days postpartum.) Milk): 27-32 can be stored at room temperature for 12 hours.

Mature breast milk (milk expressed after 6 days postpartum): 15 can be stored for 24 hours at room temperature; 19-22 can be stored at room temperature for 10 hours; 25 Store at room temperature for 6 hours.

Another situation is that the company has refrigeration equipment, or the mother expresses the breast milk in advance at home and puts it in the refrigerator, so that the breast milk can be stored for a longer time. If it is not a special situation, it is best for parents not to store breast milk for too long, and try to give the baby fresh breast milk, which is more protective for the baby's health.

Refrigerator refrigerator storage: 0-4 Refrigerated can be stored for 8 days.

If it is a small freezer box in the refrigerator, the shelf life is two weeks.

If it is a freezer compartment that is separate from the refrigerator, but the door is opened and closed frequently to pick up the items, the storage period is 3-4 months.

If it is a deep freeze chamber, the temperature is kept below 0 and the door is not opened frequently, and the storage period is more than 6 months.

The time and method of storing breast milk are as follows:

When the mother produces too much breast milk or has to go out, she needs to conserve breast milk so that she can feed her baby. The storage time of breast milk is mainly determined by the storage temperature, and the maximum storage time is 4 hours when the breast milk is about 25 after reasonable storage; When in the refrigerator 4, the maximum storage time is 72 hours; When in the freezer compartment of the refrigerator <-18, the maximum storage time is 3 months.

Before breast milk preservation, wash your hands, do not touch the inner wall of the milk reservoir, and it is best to use bottles, milk storage bags and other items with good sterilization and sealing, and place them in a specific location to avoid contamination. In addition, it is recommended that the breast milk in one container in the Royal Lead Hall should be the amount of breast milk that the baby feeds at one time, and that each small portion of breast milk be labeled with a date. If it is placed in the refrigerator compartment, it should be avoided near the refrigerator door to avoid the unconstant temperature to accelerate the deterioration of breast milk.

How to use it after saving

When you need to use it again, you should first put the breast milk into the fresh-keeping room to stir it up for thawing, and only after the ice is completely melted can you put the breast milk into a special milk simmer for hidden heating, which is generally heated for about 3 to 5 minutes. Or just put it in warm boiled water at 39 to 40 degrees Celsius to heat it up. The heating time should not exceed 10 minutes, and the temperature should not be too high, so as not to cause protein decomposition and cause nutrients to disappear.

It is normal for frozen breast milk to appear stratified, and it is enough to gently mix it and shake it well before feeding.

Reference: Health - Breast milk preservation time and method.

The storage time of breast milk is related to the method, and the preservation of breast milk is divided into three types: storage at room temperature, refrigeration, and freezing.

Keeping breast milk at room temperature is to preserve the expressed milk at 22-24 times, which can be stored for up to 4 hours, and the bottle of breast milk must be scalded with boiling water to sterilize, otherwise it is easy to breed bacteria. Refrigeration can be used for up to 3 days, and it is stored below -5 in the refrigerator. If it is frozen, the relative storage time will be longer, and the refrigerator temperature is below -18, and it can be stored for 2 months.

It is recommended to use a special milk storage bag or a thoroughly cleaned bottle to store breast milk. There needs to be a special place to put it, not with some food, vegetables, etc. Then you should record the time of each breast milk expression with a marker, so that when the baby needs it, you can take out the oldest one and use it first, and throw away the expired one.

Precautions for breast milk preservation

1. Applicable milk storage containers. According to the size of the baby's appetite, try to choose a storage container with the appropriate capacity to avoid waste caused by excessive cryopreservation. Make sure the container is clean and dry before storage, never overfill it each time, and choose a well-sealed and sterile milk bag or glass storage bottle.

2. Under normal circumstances, it is not recommended to freeze breast milk and then thaw it to the baby, which cannot guarantee the quality and nutrients of breast milk. When thawing breast milk, do not use boiling water directly, rinse the sealed bag with cold water first, and then gradually add hot water until it is completely thawed and raised to a suitable temperature, or placed in a refrigerator to thaw and deice slowly. Do not directly heat breast milk on a stove or microwave oven to prevent high temperature heating from destroying the nutrients in breast milk.

The shelf life of breast milk is divided into two types of storage: refrigerated and frozen, as follows:

1.Refrigerator preservation.

Expressed breast milk can be stored for 8 days at a temperature of 0-4. It is important to note that if the refrigeration temperature of the refrigerator is not guaranteed to be stable within this range, it is best to keep it within 24 hours, especially in the hot summer.

2.Freeze in the refrigerator.

The freezing time of breast milk is closely related to the condition of the freezer, for the freezer compartment that is isolated separately at a temperature below 0, if it is often necessary to open and close the door to take the goods, the shelf life should not exceed 3-4 months; In the case of a deep freeze chamber, that is, if the temperature is kept below -15 -18 for a long time and the door is not opened and closed frequently, the shelf life can reach six months or even longer.

The containers used to store breast milk should also be taken seriously.

The best containers for storing breast milk are frozen, well-sealed plastic and well-sealed glass and metal containers, but it is best not to use glass and metal containers, because the active factors in breast milk can adhere to the glass or metal containers, thus reducing the nutritional value of breast milk.

Look here! After a period of storage, breast milk will decompose normally, and the color may be slightly blue, yellow or brown, so mothers should not worry too much.

Steps to thaw breast milk.

When thawing frozen breast milk, rinse the sealed bag with cold water first, and then gradually add hot water to the container to allow the breast milk to thaw slowly through the sealed bag and rise to a suitable temperature for breastfeeding. Do not heat breast milk directly in the microwave or stove, as this may destroy the active substances in the breast milk.

Look here! When determining whether the temperature of breast milk is suitable, in order to prevent breast milk from being contaminated, please do not use your mouth to try the temperature, the best way is to drop some breast milk to the inside of the wrist, if the temperature is not hot or cold, it is suitable for the baby to drink!
