College of Tea Science, Yunnan Agricultural University, Kunming 650201, China

摘要

摘要: 为明确传统滇红工夫红茶和野生滇红工夫红茶的香气成分差异及呈香特点，本文选取了5个传统和5个野生滇红工夫红茶为研究材料，采用顶空固相微萃取-气相色谱-质谱（headspace solid phase microextraction-gas chromatography-mass spectrometry，HS-SPME-GC-MS）技术对二者的香气特征进行分析测定。结果表明，在10个供试茶样中共检出180种香气成分，包括醇类（31种）、酮类（19种）、醛类（33种）、酯类（32种）、酸类（11种）、碳氢类（35种）、其他类（19种）。香气活性值（odor activity value，OAV）大于1的物质有36种，二者共有物质9种。芳樟醇是传统滇红工夫红茶中贡献度较大的物质，表现为花香和甜香；芳樟醇、正己醛、壬醛是野生滇红工夫红茶中贡献度较大的物质，表现为花香、甜香、木香和果香。本研究结果为正确认识传统和野生滇红工夫红茶的香气特征提供了一定数据参考。

Abstract: To clarify differences in the aroma components and characteristics between traditional and wild Dianhong Congou black teas, five traditional and five wild Dianhong Congou black teas were investigated using headspace solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) to measure and analyze the aroma characteristics of the two types of tea. A total of 180 aroma components were detected in the 10 tea samples, including 31 alcohols, 19 ketones, 33 aldehydes, 32 esters, 11 acids, 35 hydrocarbons, and 19 other categories. Thirty-six components with odor activity values greater than 1 were identified in traditional Dianhong Congou and wild Dianhong Congou black teas, with nine components common to both. Linalool was found to be the major contributor to aroma in traditional Dianhong Congou black tea, which was characterized by a floral and sweet aroma, while linalool, hexanal, and nonanal were the most significant aroma components in wild Dianhong Congou black tea, which had floral, sweet, woody, and fruity aromas. The results of this study provide a data reference for understanding the aroma characteristics of traditional and wild Dianhong Congou black teas.

滇红工夫红茶是特指以云南大叶种1芽2~3叶鲜叶为原料，经萎凋、揉捻、发酵、干燥而制成的红条茶^[1]，因其外形条索肥壮、色泽乌润、金毫显，内质汤色红艳、滋味浓醇鲜爽、香气馥郁的品质特点而广受国内外消费者的喜爱，被誉为中国最具影响力的茶叶产品之一^[2]。滇红工夫红茶包括传统滇红工夫红茶及创新工夫红茶等种类，其中传统滇红工夫红茶是指以云南大叶种（Camellia sinensis var. assamica）茶树鲜叶为原料，经滇红工夫红茶加工工艺制成的红茶；野生滇红工夫红茶是指以野生型大理茶种[Camellia taliensis （W. W. Smith） Melchior]茶树鲜叶为原料，经滇红工夫红茶加工工艺制成的红茶^[3]。

香气是茶叶重要的品质因子，也是消费者评判茶叶品质优劣的直观标准。茶叶香气一直以来都是茶叶品质化学领域的研究热点，并已取得了许多重大研究成果^[4−6]。茶叶香气物质极易挥发，提取茶叶香气的方法对香气真实性及完整性起决定性作用。茶叶香气的提取方法包括同时蒸馏萃取法、超临界CO₂流体萃取法、固相萃取法等。同时蒸馏萃取法操作简单易行，可比较完全地提取茶叶挥发性组分，但长时间的蒸煮会使后段样品中产生蒸煮味，造成香气在一定程度上的失真，会对茶叶中低沸点挥发性成分的提取造成限制^[7]。超临界CO₂流体萃取法可比较完全地实现对茶叶香气成分的提取，但其缺点是设备的使用成本较高^[8]。固相微萃取（solid phase microextraction，SPME）具有灵敏度好、无需使用有机溶剂等优点^[9]，而顶空固相微萃取（headspace solid phase microextraction，HS-SPME）达到吸附平衡的速率更快，更适合复杂样品中挥发性组分的提取^[10]；顶空固相微萃取-气相色谱-质谱（headspace solid phase microextraction-gas chromatography-mass spectrometry，HS-SPME-GC-MS）是较为简便高效的分析鉴定茶叶风味物质的方法，通常用于检测和鉴定茶叶香气成分^[11]。

据研究结果显示，香气对工夫红茶感官品质的贡献率仅次于滋味，达到25%^[12]。目前关于工夫红茶香气的研究也已有了诸多报道，主要是集中在不同加工工艺^[13−14]、不同季节^[15−16]、不同产区^[17−18]等方面的对比研究，而不同茶树品种（或种）鲜叶加工制成的工夫红茶香气的比较研究较少，尤其是用野生型茶树和栽培型茶树鲜叶加工的滇红工夫红茶特征香气成分的差异性研究鲜有报道。

基于上述，本文利用顶空固相微萃取（HS-SPME）技术并结合气相色谱-质谱（gas chromatography-mass spectrometry，GC-MS）技术对传统滇红工夫红茶和野生滇红工夫红茶的香气进行测定，并通过主成分分析（principal component analysis，PCA）、正交偏最小二乘判别分析（orthogonal partial least squares-discrimination analysis，OPLS-DA）、聚类分析（cluster analysis，CA）等方法对二者的香气成分进行对比研究，研究结果对认识传统滇红工夫红茶和野生滇红工夫红茶香气成分间的差异，为从业者和消费者正确认识和评价传统和野生滇红工夫红茶的香气特征提供部分数据支撑及科学依据。

1.2 实验方法

1.2.1 HS-SPME操作

根据GB/T 8303-2013《茶磨碎试样的制备及其干物质含量测定》中茶试样制备法，将红茶样混匀、磨碎成粉末茶样，后准确称取0.1 g粉末茶样于20 mL顶空瓶中，加入癸酸乙酯（50 μg/g）10 μL、NaCl 0.2 g、沸水1 mL，密封瓶口，置于恒温磁力搅拌器中70 ℃平衡20 min，将老化后的萃取针头插入顶空瓶的上段顶空部分，萃取吸附40 min后取出。

1.2.2 GC-MS分析方法

GC条件：采用SH-Rtx-Wax色谱柱（30 m×0.25 mm×0.25 μm），进样口温度为250 ℃，以氦气作为载气（纯度≥99.999%），采用50:1的分流比；设定程序升温条件为初温40 ℃，以1.5 ℃/min升至70 ℃，以1 ℃/min升至72 ℃，保持2 min，然后以1.5 ℃/min升至90 ℃，保持1 min，再以5 ℃/min升至170 ℃，保持1 min，最后以9 ℃/min升至230 ℃，保持2 min。

MS条件：采用EI离子源和70 eV的电子能量，设置离子源温度为230 ℃，接口温度为240 ℃，溶剂延迟时间1.5 min。

1.2.3 香气定性和定量分析

定性分析：根据各色谱峰的质谱信息通过计算机检索与NIST 17质谱库中的标准质谱图进行对照，并参照Yang等^[19]的方法计算各香气物质的保留指数，对香气化合物进行定性分析，保留指数计算公式如式（1）所示。结合各色谱峰的峰面积进行香气相对含量分析，并根据测出的各香气成分峰面积与内标（癸酸乙酯）的比值进行相对定量。

$\rm RI = 100n+100 \times \frac{{{t_x} - {t_n}}}{{{t_{n+1}} - {t_n}}}$

(1)

式中：t_x表示待测物质的保留时间（min）；t_n表示碳原子数为n的正构烷烃的保留时间（min）；t_n+1表示碳原子数为（n+1）的正构烷烃的保留时间（min）。

定量分析：香气成分的定量采用内标法，按式（2）计算^[20−21]：

$\rm {C_i} = \frac{{{C_{is}} \times {A_i}}}{{{A_{is}}}}$

(2)

式中：C_i表示任一组分的质量浓度（μg/L）；C_is表示内标的质量浓度（μg/L）；A_i表示任一组分的色谱峰面积；A_is表示内标的色谱峰面积。

香气活性值（odor activity value，OAV）按式（3）计算^[22]：

$\rm OA{V_i} = \frac{{{C_i}}}{{O{T_i}}}$

(3)

式中：C_i表示任一组分的质量浓度（μg/L）；OT_i表示任一组分在水中的香气阈值（μg/L）。

1.3 数据处理

本实验每组数据均重复测定三次。通过Excel 2019进行数据处理，SPSS Statistics 26.0进行数据的差异显著性分析（单因素方差分析法，P<0.05，差异显著），使用Origin 2022和TBtools制图，使用SIMCA 14.1进行PCA和OPLS-DA多元统计分析。

2. 结果与分析

2.1 GC-MS分析

如表2所示，传统滇红工夫红茶和野生滇红工夫红茶10个茶样中共鉴定出180种香气成分。5个传统滇红工夫红茶共有的香气成分有31种，5个野生滇红工夫红茶共有的香气成分有42种。依据化学结构对香气成分进行归类后将香气成分划分为醇类、酮类、醛类、酯类、酸类、碳氢类、其他类7类。其中醇类物质31种，酮类物质19种，醛类物质33种，酯类物质32种，酸类物质11种，碳氢类物质35种，其他类物质19种。

醇类物质是红茶中的关键呈香物质，大多具有花果香及较低的香气阈值^[23]，容易被人类嗅觉感知。在5个传统滇红工夫红茶和5个野生滇红工夫红茶中醇类的相对含量均值分别为43.91%和47.40%。二者共有醇类物质9种，其中芳樟醇、苯乙醇、香叶醇含量较高，共同构成了滇红工夫红茶的花香、果香及甜香的香气特征。李家贤等^[24]研究发现，芳樟醇及其氧化物、苯乙醇、香叶醇为红茶醇类的主体成分，与本研究结果一致。

酮类化合物占香气成分总量的比例较小，以胡萝卜素降解产物为主^[25]。在5个传统和5个野生滇红工夫红茶中酮类化合物相对含量均值分别为2.02%和4.48%，酮类物质中具有花香、果香的3-壬烯-2-酮、α-紫罗酮和植酮含量较高，对滇红工夫红茶香气贡献较大。姚逸^[26]对10个滇红工夫红茶进行GC-MS分析后，发现β-紫罗兰酮是滇红工夫红茶的优势香气物质，对滇红工夫红茶的香气贡献较大，但本文仅在2个传统、1个野生滇红工夫红茶中检出该成分，可能是原料产地及茶树品种的差异造成的。

醛类化合物大部分是脂肪酸、氨基酸代谢途径的产物，通常具有花香、果香的特征^[27]。在5个传统和5个野生滇红工夫红茶中醛类化合物相对含量均值分别为13.75%和18.84%，其中正己醛、苯甲醛、苯乙醛为二者共有且含量较高，构成了滇红工夫红茶花果香的香气特征。张韵等^[28]研究发现，3种高香工夫红茶中含量较高的醛类物质为苯甲醛、苯乙醛，与本研究结果一致。

酯类物质通常呈现令人愉悦的花香和果香的香气特征^[29]。在5个传统和5个野生滇红工夫红茶中酯类化合物相对含量均值分别为29.34%和20.85%，水杨酸甲酯在传统和野生滇红工夫红茶中均有检出且含量较高，是滇红工夫红茶的花香香气特征来源之一。岳翠男等^[30]研究表明，水杨酸甲酯是浮梁红茶中的含量较高的酯类物质，与本研究结果一致。

从图1可知，醛类（清香、焦香和花香属性）占比最大，为20.39%~27.06%，其次是醇类（花果香、木香属性）和酯类（果香属性），分别占比为16.25%~23.86%和17.05%~23.30%，三者共同构成了滇红工夫红茶花香、果香、木香的主要香气特征。

2.2 传统滇红工夫红茶和野生滇红工夫红茶特征性香气物质分析

挥发性物质在茶汤中的质量浓度及其阈值对滇红工夫红茶的品质特征风味有较大贡献^[31]。OAV是挥发性物质的浓度与其在样品中检测阈值的比值，能反映该香气化合物对样品整体香气的贡献度，大于1的化合物被认为是关键风味物质，可影响样品整体风味，且OAV值越大表明该物质对供试样品的整体风味贡献越大^[32−33]。经分析计算传统与野生滇红工夫红茶的各类主要香气成分的OAV值后，共发现36种OAV值大于1的化合物，其定性定量结果如表3所示。两类滇红工夫红茶共有的香气成分有9种，包括辛醇（脂蜡香气、柑橘香）、芳樟醇（甜香、铃兰花香、木香）、香叶醇（玫瑰花香、甜香）、α-紫罗酮（木香、紫罗兰香气）、正己醛（木香、清香、果香）、苯乙醛（花香）、壬醛（玫瑰花香、蜜蜡花香）、癸醛（甜橙和橘子香气、有油脂气息）、水杨酸甲酯（冬青香、清香、花香）^[34−38]，其中香叶醇在除WY以外的茶样中OAV值均大于10，癸醛在除BY以外的茶样中OAV值均大于10，壬醛在除LM以外的茶样中OAV值均大于10，芳樟醇和正己醛在所有茶样中的OAV值均大于10，对滇红工夫红茶花香、甜香、果香的香气特征有重要贡献。

与传统滇红工夫红茶相比，野生滇红工夫红茶中辛醇、芳樟醇、α-紫罗酮、正己醛、苯乙醛、壬醛的OAV值均较大；1-辛烯-3-酮（蘑菇香）^[39]在5个传统滇红工夫红茶茶样中仅有1个茶样检出，在5个野生滇红工夫红茶茶样中有4个茶样检出且OAV值均超过100，对野生滇红工夫红茶的香气贡献极大；反式-2-壬醛（黄瓜，油脂）^[40]在5个传统滇红工夫红茶茶样中有2个茶样检出，在5个野生滇红工夫红茶茶样中全部检出且OAV值均超过10。

2.3 PCA分析

对OAV法筛选出的9种共有香气成分进行PCA分析，结果如图2所示，R²X（cum）（累计解释率）为0.997，Q²（cum）（整体模型预测能力）为0.837，表明本模型的拟合度较高，预测能力较好。图2所示为PCA的得分散点图，第一主成分解释率R²X为0.585，第二主成分解释率R²X为0.216，在置信区间为95%的情况下10个滇红工夫红茶的样本点分散，且无异常值，表明样本有较高区分度。

图3为PCA的模型因子荷载图，其中正己醛、芳樟醇、α-紫罗酮、壬醛、辛醇、水杨酸甲酯、苯乙醛、癸醛在PC1上呈正相关，香叶醇在PC1上呈负相关，香叶醇、正己醛、芳樟醇、α-紫罗酮在PC2上呈正相关，壬醛、辛醇、水杨酸甲酯、苯乙醛、癸醛在PC2上呈负相关，表明传统滇红工夫红茶与野生滇红工夫红茶以香叶醇和辛醇为主要成分，这与Wang等^[41]的研究相符。

2.4 OPLS-DA分析

为了进一步验证PCA分析的合理性，识别传统和野生滇红工夫红茶的香气特征，减小误差，建立了OPLS-DA模型^[42]。选取变量投影重要度（variable importance for the projection，VIP）预测值大于1的点为差异成分（图4）。组间在200次假设验证的前提下，所有模型的R²值（累计方差）与Q²值（累计交叉有效性）都低于右侧值且回归线的斜率大于1，说明模型拟合良好。

BM与BY组间R²（cum）=0.999，Q²（cum）=0.999，两组间区分度较高，VIP值大于1的物质包括辛醇（1.25）、芳樟醇（1.003）、壬醛（1.01）、癸醛（1.16）、正己醛（1.22），为两组间的差异成分。FM与FY组间R²（cum）=0.998，Q²（cum）=0.996，两组间区分度较高，VIP值大于1的物质包括苯乙醛（2.15）、正己醛（1.38），为两组间的差异成分。LM与LY组间R²（cum）=0.997，Q²（cum）=0.995，两组间区分度较高，VIP值大于1的物质包括壬醛（1.77）、癸醛（1.01）、正己醛（1.06），为两组间的差异成分。SM与SY组间R²（cum）=0.965，Q²（cum）=0.995，两组间区分度较高，VIP值大于1的物质包括辛醇（1.03）、壬醛（1.06）、水杨酸甲酯（1.46）、香叶醇（1.31），为两组间的差异成分。WM与WY组间R²（cum）=0.998，Q²（cum）=0.997，两组间区分度较高，VIP值大于1的物质包括苯乙醛（1.43）、辛醇（1.11）、壬醛（1.002），为两组间的差异成分。

2.5 聚类分析

筛选出传统和野生滇红工夫红茶共有的OAV值大于1的9种香气物质绘制聚类热图（图5）。如图5所示，10个供试滇红工夫红茶样品可聚为两大类，此结果与本研究滇红工夫红茶的分类一致。栽培型云南大叶种茶树鲜叶制成的传统滇红工夫红茶LM、BM、SM、WM与FM聚为一类，芳樟醇含量在本类中相对较高，可以推测此类供试样的香气特征以花香和甜香为主。野生型大理茶种茶树鲜叶制成的野生滇红工夫红茶SY、LY、WY、FY和BY聚为另一类，芳樟醇、正己醛、壬醛含量在本类中相对较高，可以推测此类供试样的香气特征以花香、木香、果香、甜香为主。野生滇红工夫红茶的正己醛、壬醛含量明显高于传统滇红工夫红茶，两类滇红工夫红茶之间的香气含量差异较为明显。

3. 结论

香气、汤色、滋味、外形是滇红茶的核心品质特征，不同茶树品种间挥发性香气物质的种类及含量的差异对滇红工夫红茶的香气类型有着一定影响。本文以传统滇红工夫红茶和野生滇红工夫红茶为研究对象，采用HS-SPME-GC-MS技术结合OAV法及PCA、OPLS-DA、聚类分析等方法，进行香气成分的鉴定及比较分析，明确了传统和野生滇红工夫红茶的主要香气化合物类别、含量、OAV值。供试的两类滇红工夫红茶的香气成分、含量能较好区分。OAV值大于1的香气成分共36种，其中芳樟醇和正己醛的OAV值在10个茶样中均大于10，此外，香叶醇、壬醛和癸醛的OAV值在10茶样中有9个茶样都大于10，是构成滇红工夫红茶花香、木香、甜香、果香的主要香气特征成分。二者共有的关键香气组分有9种，以香叶醇和辛醇为主要成分。野生滇红工夫红茶在传统滇红工夫红茶花香、甜香的基础上，更体现出木香和果香的香气特征。研究结果为正确认识和科学描述以栽培型茶树品种和野生型茶树品种鲜叶为原料制成的2种滇红工夫红茶的香气特征提供了一定的理论基础和数据支撑，也为2种滇红工夫红茶的品质评价提供了一定的借鉴作用。后续还可丰富供试样本容量，如增加不同采摘季节、不同产地供试样本等，以构建更加科学精准的评价体系。
