采取高温(36℃)、薄摊(1和3 cm)、短时(4 h)发酵工艺,再配合清洗鲜叶、在发酵叶堆表洒水等操作,研究了适合清洁化、机械化流水线的滇红加工工艺对滇红茶感官品质及理化性质的影响。结果表明,8种高温、薄摊、短时发酵工艺制作的红茶,均具备滇红的感官及理化品质特征,其中以清洗鲜叶、摊叶厚度3 cm,且在发酵茶堆表洒水的处理感官品质较好;此外,发酵时摊叶厚度为3 cm 且在发酵叶堆表洒水,可弥补清洗鲜叶带来的不利影响,并提高茶叶水浸出物的含量,但需适当加深发酵程度,平衡发酵茶堆表洒水与茶汤苦涩味之间的矛盾。
採取高溫(36℃)、薄攤(1和3 cm)、短時(4 h)髮酵工藝,再配閤清洗鮮葉、在髮酵葉堆錶灑水等操作,研究瞭適閤清潔化、機械化流水線的滇紅加工工藝對滇紅茶感官品質及理化性質的影響。結果錶明,8種高溫、薄攤、短時髮酵工藝製作的紅茶,均具備滇紅的感官及理化品質特徵,其中以清洗鮮葉、攤葉厚度3 cm,且在髮酵茶堆錶灑水的處理感官品質較好;此外,髮酵時攤葉厚度為3 cm 且在髮酵葉堆錶灑水,可瀰補清洗鮮葉帶來的不利影響,併提高茶葉水浸齣物的含量,但需適噹加深髮酵程度,平衡髮酵茶堆錶灑水與茶湯苦澀味之間的矛盾。

This testw as conducted to study the influence ofprocessing technologies w hich w ere appropriate forcleaning and m echanization on the quality and physicochem icalcharactersofD ian B lack Tea ,by the m ethod oftraditionalferm entation technology w ith high tem perature (36℃),thin layer(1 and 3 cm )and shortperiod (4 h),and added the processes ofcleaning fresh tea leaves and purling w ateron the surface of ferm ented heap.The resultsshow ed thatthe 8 kindsofblack tea producted by the processing technology allhad the quality characters ofD ian black tea,ofw hich dealtw ith cleaning ,heaping 3 cm deep and purling w ateron the surface had a betterexpression.The lattertw o diaposes also could offsetthe?adverse effectthatw as broughtby cleaning the fresh leaves and could raise the extraction contentfrom w ater,butw e need to balance the contradiction ofspurting w ateron the surface offerm ented tea heap and the bitterand astringentflavors infusion through intensifying ferm entation.
