Placing milk in vitro for a period of time will lead to the growth of bacteria. Even if it is heated, it may induce acute gastroenteritis after feeding the baby. It is recommended not to stay for more than 2 hours and heat. If you want to drink breast milk in three to five days, you can store it in the fresh-keeping room. If you want to store it for a long time, you must store it in the freezer. If the freezer temperature is below-18 degrees Celsius, it can be frozen for four months, but it should be noted that milk must be cooled before it can be frozen in the refrigerator.
Extended data:
Breast milk is the most natural, safest and most complete natural food for baby's growth. It contains all the nutrients and antibodies needed by the baby's growth, especially breast milk contains 50% fat, which not only supplies the baby's body heat, but also meets the fat needed by the baby's brain development (60% of the brain structure comes from fat). Rich in calcium and phosphorus can make the baby grow tall and strong; Immunoglobulin can effectively prevent and protect infants from infection and chronic diseases; Bifidobacterium and oligosaccharide can inhibit the reproduction of intestinal bacteria and help digestion. In addition, the intimate contact and parent-child relationship of breastfeeding can stimulate the brain and intellectual development of infants.
The frozen preservation of breast milk is related to the condition of refrigerator.
1. If it is a small freezer in the freezer, the shelf life is two weeks.
2. If it is a freezer separate from the freezer, but the door is often opened and closed to take items, the storage period is 3 ~ 4 months.
3. If it is a deep freezer, the temperature should be kept below 0℃, and the door should not be opened frequently, and the storage period should be more than 6 months.
4. The stored breast milk will decompose and look a little blue, yellow or brown, which is normal.
5. When the frozen breast milk is thawed, the sealed bag should be washed with cold water first, and hot water should be gradually added until the breast milk is completely thawed and raised to a temperature suitable for feeding, or it should be slowly thawed and deiced in the cold room.
6. After thawing, pour directly into the bottle to feed the baby. Thawed breast milk must be eaten within 24 hours and cannot be frozen again.
