Production of shirakamba Birch Sap Beyrage

白桦的导电汁液含有糖、有机酸、氨基酸和矿物质。在一个季节中获得的汁液量可达150升，但有机和无机成分的浓度不到1%。因此，与其将树液浓缩制成糖浆，不如将树液作为饮料使用。为了向城市市场提供树液，已经开发了树液装瓶工艺。具有加热杀菌工艺的保鲜工艺效果良好。毛细管电泳分析是瓶装果汁质量控制的有效手段。3)研制了一种微过滤冷却巴氏杀菌槽工艺，对果汁的保存效果很好，由于该工艺不含加热过程，因此保存的果汁味道不发生变化，保持了果汁的新鲜。4)对树液进行冷冻干燥，可有效浓缩树液，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.
