How to pick blueberries Fresh and delicious blueberry juice must be a favorite of many people in summer. However, as a seasonal fruit, how does blueberry choose blueberries? I believe many people will have such questions, may wish to follow Xiao Bian to steal a trick. Blueberry fresh fruit selection method: The blueberry fruit picked from the blueberry tree has a white layer of fruit cream, which is an important source of blueberry aroma and nutrition. Blueberry fresh fruits purchased in the supermarket are generally packed in 125g plastic boxes. The freshness of blueberries must be checked before purchase. The specific methods are as follows: 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, full 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! How to save blueberries Summer is the season when blueberries are marketed. Blueberries are rich in nutrients and are loved by many people. How to save blueberries? Although many people like to eat blueberries, they do not necessarily know how to preserve blueberries. The following small series on a brief introduction to the blueberry preservation method! 1. Fresh blueberries need to be stored at a temperature below 10°C, even if they are kept below 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 fruits in the field in order to effectively prevent decay. Pre-cooling methods mainly include vacuum cooling, cold water cooling, and cold air cooling. Vacuum Cooling: Vacuum cooling is the way the fruit cools by evaporating the surface water. In this way, the cooling rate is fast and can be completed in 20 to 30 minutes. Cold water cooling: impregnated with 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: The use of a freezer to cool the cold fruits. 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 room, but the cooling rate is slow when there is an outer box, in order to achieve heat exchange as soon as possible, in the packaging on the hole; 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. 2, frozen storage 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, and 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.
