[0002] Blueberries, scientifically known as Vaccinium uliginosum, have berries that are blue, nearly round, with delicate flesh and a moderate sweet and sour taste. In addition to containing sugar, acid, and VC, they are also rich in VE, VA, VB1, SOD, etc., ursolic acid, anthocyanins, protein, fat, as well as abundant trace elements such as iron, zinc, and manganese. It is highly regarded as one of the "five healthy fruits" by the Food and Agriculture Organization of the World, and has the laudatory names of "queen of fruits" and "king of berries". The picking period of blueberries is relatively short (about 20 days), and if not frozen immediately after being picked, they will rot. Therefore, if a large amount of blueberries are on the market and cannot be digested by the market in time, it will cause a large amount of economic losses. Currently, in addition to selling blueberries as fresh fruits, in most blueberry production areas in China, they are processed into by-products such as blueberry beverages, blueberry wine, blueberry jam, or freeze-dried blueberries for sale.
