Fresh milk can be stored in the refrigerator for a few days, and fresh milk can be stored in the ref

Refrigerated: 5-6 days.

The common refrigeration temperature for food in the refrigerator is 4 to 8 °C, where the growth rate of most bacteria slows down. However, some bacteria are cold-loving, such as Yersinia and Listeria can grow and multiply rapidly at this temperature, and if you eat food infected with these bacteria, it will cause intestinal diseases. In the freezer of the refrigerator, the temperature is generally about minus 18, and at this temperature, bacteria will generally be inhibited or killed, so the food stored in it has a better preservation effect.

However, freezing does not mean that it can completely kill bacteria, and there are still some bacteria with strong frost resistance that will survive. So, from another point of view, if the refrigerator is not disinfected frequently, it will become a "breeding ground" for some bacteria.

Therefore, fresh milk should not be kept in the refrigerator for more than 6 days, and be careful not to put it in the freezer, but should be placed in the refrigerator.

Up to 3-5 days.

Fresh milk refers to milk within 24 hours of the milk being separated from the cow's body, otherwise it cannot be called "fresh" milk.

There are two types of liquid milk: room temperature milk and low temperature fresh milk!

Therefore, as a general rule, drink it as soon as possible, do not put it in the refrigerator, even if it is left in as short a time as possible.

Try to drink fresh milk after opening the bottle, try not to drink it for more than 24 hours at room temperature, and do not put it in the refrigerator for more than 3 days, which is easy to breed bacteria and induce bloating and diarrhea.

It is best to place fresh milk in the refrigerator immediately after opening, and it should not be put in the freezer, as its quality will be damaged. It is best to set the refrigerator temperature between 4 and 8 degrees Celsius. If the thermostat is mechanical, the gear should be adjusted reasonably according to the seasonal temperature, generally adjusted in 1 2 gear in summer, 3 gear in spring and autumn is better, and 4 5 gear can be adjusted in winter.

Precautions for the preservation of fresh milk

In winter, the temperature in the environment is low, the room temperature and the freshness layer in the refrigerator are about the same, and there are few fungi in the environment, and the pure milk at this time can be stored for 1 2 days.
