    摘要:

    本研究采用固相微萃取(SPME)结合气相色谱-质谱联用(GC-MS)、感官定量描述分析及气味活度值(OAV)分析,系统研究了不同嫩度原料、干燥温度下‘中黄1号’工夫红茶香气品质及成分组成的变化。结果表明,‘中黄1号’工夫红茶共检测出酯类、醛类、杂环类、醇类、酮类等124种挥发性成分;结合偏最小二乘判别分析(PLS-DA)和OAV筛选出不同嫩度原料间9种显著性差异的关键挥发性成分,包括2,3-辛二酮,癸醛,2,4二甲基苯甲醛,2-羟基苯甲酸乙酯,异丙烯基吡嗪,2-乙酰基-5-甲基呋喃,苯乙醇,D-柠檬烯,b-月桂烯。‘中黄1号’工夫红茶主体香气为甜香,高成熟度原料呈现甜香带果香风格,其中2,3-辛二酮、异丙烯基吡嗪对果香形成至关重要,而2,4-二甲基苯甲醛、苯乙醇、β-月桂烯含量减少与高成熟度样品甜香强度降低相关。此外,随干燥温度升高,异丙烯基吡嗪、2-乙酰基-5-甲基呋喃含量增加提高了样品火工味。本研究结果为‘中黄1号’红茶香气品质提升及生产工艺优化提供了理论参考。

    Abstract:

    SPME coupled with GC-MS, quantitative descriptive sensory analysis, and odor activity value (OAV) analysis were used to systematically examine the effects of raw material tenderness and drying temperatures on the aroma quality characteristics of the cultivar "Zhonghuang 1" cooked black tea. The findings revealed that sweetness serve as the primary aroma of "Zhonghuang 1" Congou black tea, with sample of higher maturity additionally presenting subtle fruity notes. A total of 124 volatile components were detected in black tea samples, including esters, aldehydes, heterocyclics, alcohols, and ketones. By combing PLS-DA and OAV, 9 key volatile components were identified: 2,3-octanedione, decanal, 2,4-dimethylbenzaldehyde, ethyl 2-hydroxybenzoate, isopropenylpyrazine, 2-acetyl-5-methylfuran, phenylethanol, D-limonene, and β-myrcene. Among these components, 2,4-dimethylbenzaldehyde, phenylethanol, and β-myrcene are associated with sweetness; while 2,3-octanedione and isopropenylpyrazine play a crucial role in the formation of the fruity aroma in higher maturity samples. Additionally, isopropenylpyrazine and 2-acetyl-5-methylfuran contribute significantly to enhance the roasted aroma of the samples. The results of this study offer a theoretical basis for improving the aroma quality and optimizing the production process of "Zhonghuang 1" black tea.
