罐装绿茶水生产工艺的初步研究

拟采取的罐装绿茶水生产工艺特点是：茶鲜叶绿杀青后，直接烘干作为原料，避光真空沸水浸出，通过研究发现，杀青后直接烘干的处理样在色泽、香气、滋味上均优于炒青绿茶对照样；避光真空浸出有利于茶汤护色；避光人无离子水浸出在减少沉淀产生方面有明显效果，同时还发现，烘干的处理样出现高浓的熟栗香；避光真空条件下自来水同的汤色比无离子浸出的汤色绿色度高。

A Preliminary Study on Manufacturing Methods of Canned Green Tea Drinks

The canned green tea drinks were made from the dry tea which was directly roasted from fresh tea shoots after de enzymed by soaking under non light and vacuum.This kind of roasted tea was found to be superior to potfried tea in colour,aroma and taste.The soaking process under non light and vacuum can protect colour of drinks and decrease precipitation and produce high roasted chestnut aroma.Tap water was better than non ion water under non light and vacuum in keeping this tea drinks' green color.
