【摘要】：香氣是影響茶葉品質(zhì)的重要因子之一,太平猴魁茶是歷史名茶,其獨(dú)特的香氣受到消費(fèi)者青睞。本研究利用頂空固相微萃取-氣質(zhì)聯(lián)用結(jié)合主成分分析法對(duì)太平猴魁茶的香氣成分進(jìn)行研究。結(jié)果表明:從太平猴魁茶樣品中共檢測(cè)到51種揮發(fā)性成分,3個(gè)不同地域的7個(gè)太平猴魁茶樣品香氣成分在組成及含量上存在一定的差異,但它們的主要香氣物質(zhì)是相似的,主要包括13種醇類物質(zhì)、8種烯類物質(zhì)、6種醛類、3種酮類物質(zhì)、7種酯類物質(zhì)、4種芳香烴類物質(zhì)和8種烷烴類物質(zhì);采用主成分分析法,鑒定出太平猴魁茶特征香氣成分主要有29種,包括7種醇類成分,8種烯類成分,3種醛類成分,5種烷烴類成分,2種酮類成分,3種酯類成分和1種芳香烴類成分。
[Abstract]:Aroma is one of the important factors affecting the quality of tea. Taiping Houkui Tea tea is a famous tea of history, and its unique aroma is favored by consumers. The aroma components of Taiping Houkui Tea tea were studied by headspace solid phase microextraction-GC-MS and principal component analysis. The results showed that 51 volatile components were detected from Taiping Houkui Tea tea samples. There were some differences in composition and content of aroma components in 7 Taiping Houkui Tea tea samples from three different regions, but their main aroma substances were similar. It mainly includes 13 alcohols, 8 alkenes, 6 aldehydes, 3 ketones, 7 esters, 4 aromatic substances and 8 alkanes. The main aroma components of Taiping Houkui Tea tea were identified as 29 kinds, including 7 alcohols, 8 alkenes, 3 aldehydes, 5 alkanes, 2 ketones, 3 esters and 1 aromatic hydrocarbon.
