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.
