摘要: 针对当前出口炒青绿茶品质存在的“色泽不绿、苦涩味重、有烟焦味”等突出问题进行鲜叶摊放、蒸汽杀青、脱水等关键工艺研究,综合提出长炒青绿茶、圆炒青绿茶加工新工艺。采用新工艺加工的炒青绿茶,汤色改善明显,无烟焦味。长炒青绿茶氨基酸含量提高23.8%,感官审评综合得分提高一个等级(+3.8分);圆炒青绿茶氨基酸和叶绿素含量分别提高5.2%和5.6%。

Abstract:  For improving the quality of traditional Chinese roasted green tea, fresh leaf spreading, steaming to de-enzyme, anddehydrating for new-type roasted green tea process were studied. Compared with the traditional processing technique, this newprocessing technique of long-shape roasted green tea could not only improve the infusion color without smoking-smell, but alsoincreasing the amino acid content by 23.8% and total sensory test score up to 3.8. For the round-shape roasted green tea, thisnew technique could also improve the liquor color without smoking-smell, and increase the amino acid content by 5.2% andchlorophyll content up to 5.6 %.
