不同萎凋方式对滇红茶香气物质的影响研究
Study on the Impact of Different Withering Methods on the Aroma Compounds of Yunnan Black Tea
摘要
Abstract
In order to investigate the influence of shaking withering,sun withering,sun-natural combined withering,natural withering and warm-air withering on the aroma compounds of Yunnan black tea,spring fresh tea leaves of'Yunkang 10'with one bud and two leaves were selected as the raw material to process Yunnan black tea using the above five drying methods under the same conditions of other process parameters,and the aroma compounds of the tea samples were detected and analyzed..The results showed that a total of 227 volatile compounds were detected,including 58 alcohols,36 aldehydes,23 ketones,59 esters,42 hydrocarbons,and 9 others,among them,alcohols had the highest proportion;There were 46 aromatic substances showing significant differences(P<0.05).Furthermore,all the significantly different aldehydes had a higher proportion in the shaking withering treatment compared to other withering methods.The analysis of Relative Odor Activity Values(ROAV)showed that a total of 32 substances were with ROAV≥0.1,among which 19 substances had significantly different ROAV values(P<0.05).Although different withering methods cannot change the main substances of Yunnan black tea aroma,they have a significant impact on the abundance and proportion of aroma substances,especially the shaking withering method,which differs significantly from other withering methods.The research results can provide a certain reference for selecting suitable withering methods for the processing of Yunnan black tea and the processing of high-aroma Yunnan black tea.关键词
