Generally speaking, the blueberry bought can be rinsed with fresh water. If you are concerned about pesticide residue, you can use salt water to soak, then rinse with water. Here are two ways to clean blueberries for you, but also teach you how to properly preserve blueberries?
Blueberry cleaning method
Wild blueberry water rinse gently
The blueberry fruit powder and skin contain rich anthocyanin and other high-value nutrients. Therefore, the best way to clean the blueberries is to not destroy the white powder on the skin as much as possible. Wild blueberries need only a little clear water to gently rinse and remove the surface. Dust on the wash can be. This will preserve the fruit powder on the blueberry fresh fruit skin.
Blueberry Bubbles Available on the Market
In order to prevent the pesticides from blueberries grown on the market, it is best to wash the blueberries in the market with salt water. The fresh blueberries were immersed in the water for 10 minutes. During the foaming process, stir several times by hand and rinse with clean water. Or you can use salt water, then rinse, and finally use a clean blisters.
Blueberry preservation method
Blueberry fresh fruit needs to be stored at a temperature below 10°C, even under the temperature of 10°C during transportation. 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.
Vacuum cooling
Vacuum cooling is the way the fruit cools through the evaporation of surface moisture. This way, the cooling rate is fast and can be completed in 20 to 30 minutes.
Cold water cooling
Immerse in cold water or spray cold water. This method is more efficient and faster than cold air cooling, but it is prone to fruit spoilage.
Cold air cooling
That is, the cold air is used to cool the fruits in a freezer. Using this method to cool the fruit has a high utility value. Divided into forced cooling and differential pressure cooling, forced cooling is forced into the cold air into the pre-cooling, but there is a slow cooling rate when the outer box, in order to achieve rapid heat exchange, can be punched in the packaging; differential pressure cooling in the pre Holes are punched on both sides of the outer box in the cold storage room, and cold air is introduced into the box with strong cooling air to achieve rapid cooling.
Cryopreservation
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.
Blueberry selection method
1, to see the number of white fruit on the surface of the fruit, blueberry cream and more fresh high, less or no fruit cream, blueberry freshness is poor;
2. Check the bottom of the blueberry box. If a pink liquid is found, it indicates that there is rotten fruit in the box. In Japan's high-end supermarkets, fresh blueberries must be thrown away the same day. In Hong Kong supermarkets, fresh fruits cannot be sold on the same day and prices are reduced by about 50%. Therefore, the price of fresh fruit sold in supermarkets is related to freshness, and does not represent the true market price.
Like many fruits, fresh blueberries should be firm and look dry, plump and smooth. In general, blueberries do not carry leaves and stems. Keep in mind that the size of the head is not a sign of whether the blueberry fruit is ripe, but the color of the blueberry is important. The fruit of ripe blueberries should be between deep purple and blue-black. This blueberry is delicious!
