Blueberry preservation method

1, the preservation of fresh blueberries

Buy fresh blueberries and put them into the refrigerator immediately. The best storage temperature is 1~3°C. Can be insured for 5-7 days. If you want to eat fresh blueberries, do not put in a cold storage below 0°C.

It is not advisable to wash the blueberries with water and put them into the refrigerator. Because water can easily rot the blueberries, keeping the appearance of blueberries dry is the only way to prolong the shelf life of fresh blueberries.

Blueberry fresh fruit should also maintain temperatures below 10°C during transport. However, fruits falling from the field temperature below 10°C must be subjected to a pre-cooling process to remove heat from the field fruits in order to effectively prevent decay. Precooling methods mainly include vacuum cooling, cold water cooling, and cold air cooling.

2. Make the blueberry jam and save it

Blueberry fruit is berry type, strong storage resistance, in the indoor room temperature of 18-26 degrees, the use of small packages of fresh fruit can be preserved for two weeks without changing the original flavor, such as cryopreservation of its preservation period will be longer, modified atmosphere storage up to 3 months about.

In fact, the preservation time of blueberries is still relatively long, even so it can not be taken lightly, save blueberries for longer food storage time.

After harvesting and packaging of fruits, they can be quickly frozen and processed into quick frozen fruit. Fast-frozen fruit can effectively control the decay and extend the storage period, but the raw food taste is slightly acidic. Freezing temperature requirements below -20 °C. Polythene bags are available in 10kg and 13.5kg sizes. Freezing conditions are also required during transportation.

Processing of frozen fruit is a trend in the utilization of berry fruits. Blackberries, raspberries, and strawberries can be processed for frozen fruit. However, the above three types of berries are prone to discoloration and cracking when frozen, but blueberry fruits do not have this phenomenon after freezing. Relative to strawberry, raspberry and other fruits, blueberry fruit texture is hard, suitable for frozen fruit processing.
