Preservation method

First of all, it needs to be stored in a refrigerator below - 10 degrees. If it is in the process of transportation, it also needs to preserve this temperature, because this precooling process can effectively prevent it from rotting. Therefore, the cooling methods of precooling include cold water cooling, cold air cooling and vacuum cooling respectively

Vacuum cooling

The effect of vacuum cooling is very good. It can be cooled quickly to evaporate water, so as to achieve the function of cooling. It often takes half an hour to reach

Cold water cooling

This method of cooling with cold water is faster than vacuum cooling because it can maintain the temperature of blueberries. However, one of the bad characteristics of this method may cause the consequences of fruit decay

Cold air cooling

The effect of cold air cooling is very good. The temperature can reach a certain temperature effect through cold air cooling, which is conducive to preservation

Minor supplement

In addition to the above methods, there is also a way of cryopreservation. Put the blueberries in the refrigerator and freeze them. The freezing temperature is below - 20 degrees, which can effectively preserve the temperature of blueberries. But this way, there will be fruit cracking. It is easy to change color when frozen for a long time

Blueberry is a kind of fruit we like to eat, but it needs some ways to preserve it well. The above methods have advantages and disadvantages. I hope you can use these methods flexibly
