Method for extracting tea enzyme deactivation top note

The invention relates to a method for extracting tea enzyme deactivation top note. At the enzyme deactivation stage, distilled steam is condensed; condensed water containing top note is obtained; petroleum ether is added into the condensed water for extraction; extracts are dried to obtain enzyme deactivation top note. In the tea processing process, the enzyme deactivation temperature is too high,so that the tea aroma is lost; waste and environment pollution are caused. The enzyme deactivation top note can be applied to top-level tea for improving the aroma and can also be applied to the fields of beverage and food. Better economic and social benefits are realized. 本发明涉及提取茶叶杀青头香的方法，将杀青阶段蒸馏出的蒸汽进行冷凝，获得含有头香的冷凝水，向冷凝水中加入石油醚，进行萃取，将萃取物烘干即得杀青头香。茶叶加工过程中由于杀青温度过高，导致茶叶香气的散失，既浪费又污染环境。杀青头香既可应用于顶级茶叶提高香气，也可以应用于饮料、食品领域，具有较好的经济和社会效益。
