Birch sap is rich in a variety of amino acids required by the human body, and various minerals, especially calcium, magnesium, potassium, sodium, phosphorus, germanium, selenium and other trace elements. Birch sap liquid beverages are packaged in bags and bottles. During the production process of birch sap beverages, it is necessary to test the net content of the birch sap beverages to ensure that the net content error of the produced packaged liquid beverages is within an appropriate range.
