Aroma Characteristics and Differences of Wuyi Rock Tea Shuixian with Different Storage Years
摘要
Abstract
In order to explore the aroma characteristics and differences of Wuyi rock tea Shuixian with different storage years,the aroma components of Shuixian with eight different storage years were analyzed by electronic nose analysis technology combined with gas chromatography-mass spectrometry (GC-MS). The analysis results of electronic nose showed that there were differences in response values mainly among sensitive sensors of nitrogen oxide (NOx),sulfur compound and aromatic compound. The response value of Shuixian stored in 2012 and 2006 was much higher than that stored in other years,indicating that Shuixian stored in 2012 and 2006 contained higher NOx,sulfur compound and aromatic compound. GC-MS showed that Shuixian with different storage years could be classified into three types related to storage years according to the similarity of aroma compound profiles:2020,2012-2018 and 2006-2010.In the tea samples of 2020,contents of nerolidol,(Z)-3-Hexenyl hexanoate,pyrrole,methyl salicylate,β-ionone and hexyl caproate were relatively high;in the tea samples of 2012-2018,the contents of nerolidol,β-ionone and pyrrole were relatively high,among which the content of nerolidol decreased year by year with the increase of storage years,and the contents of β-ionone and pyrrole did not change much;in the tea samples of 2006-2010,the contents of β-ionone and benzaldehyde were higher,among which the content of β-ionone decreased with the increase of storage years. The aroma components of the three types of Shuixian were significantly different,most of them showed a downward trend.关键词
