技术介绍
古今典籍证明,桑叶是植物之王,有“人参热补,桑叶清补”之美誉。桑叶,是国家卫生部确认的“药食同源”植物,被国际食品卫生组织列入“人类21世纪十大保健食品之一”,成为人类绿色新食品源。桑叶内含有一种叫做脱氧野尻霉素(DNJ)的生物碱,这是一种仅存在于桑叶中的一种生物碱,含量约100mg/100g,这种生物碱是一种α-糖苷酶的抑制剂。桑叶中不仅含有DNJ,而且含有丰富的γ氨基丁酸和植物淳,其含量是绿茶的3~4倍。具有减肥、美容、降血糖的作用,桑叶茶中还含有大量的矿物质元素。民间有很多利用桑叶制作的饮品和菜肴。现在更多的人们习惯把桑叶制成茶叶,称为桑叶茶或绿茶,因其丰富的成分和保健功能,是白领人士日常饮品的首选之一,故有人把桑叶茶被称为“神仙茶”。但是现有的桑叶茶,采取的多是传统的制茶技术,在去除桑叶茶青气和苦涩的同时,不可避免的会使桑叶中的很多微量元素和营养成分、药用功效大大丧失,失去了该茶应有的保健功能。
