Production of shirakamba Birch Sap Beyrage

1)白桦树的导电汁液含有糖、有机酸、氨基酸和矿物质。一个季节获得的汁液量达到150升，但有机和无机成分的浓度小于1%。因此，树液更适合用作饮料，而不是将树液浓缩成糖浆。2）开发了树液装瓶工艺，以向城市市场提供树液。具有加热灭菌过程的保存过程效果良好。毛细管电泳分析是瓶装树液质量控制的有效手段。3）研制了一种带有微滤过程的冷却巴氏杀菌罐，它能很好地保存树液。由于该过程不包含加热过程，因此保存的树液的味道不会改变，保持树液新鲜。4）树液的冷冻干燥有效地浓缩树液而不发生化学变化。

1)Conductive sap from shirakamba birch contains sugars, organic acids, amino acids, and minerals. The amount of the sap obtained in a season reaches to 150 l, but concentration of the organic and inorganic components are less than one percent. Therefore, the sap is more suitable to use as beverage than to concentrate the sap for getting syrup.2)A bottling process of sap has been developed to provide the sap to the urban market place. The preservation process having heating sterilization process works well. Capillary electrophoresis analysis is an effective apparatus for the quality control of the bottled sap.3)A cooling pasteurizer tank with a microfilter process has been developed and it works well to preserve the sap. Since the process does not contain heating process, the taste of the preserved sap does not change keeping the sap fresh.4)Freeze drying of the sap is effective to concentrate the sap without chemical change.
