| 摘 要： | 对烤烟新品种‘渝金香1号’的致香物质含量进行分析,为该品种的栽培技术改进以及卷烟配方应用提供依据。取重庆市巫山县烟区的‘渝金香1号’以及主栽烤烟品种‘云烟87’、‘K326’（对照）中部C3F等级烟叶,经蒸馏萃取后,采用气相色谱质谱联用法测定其致香成分及含量。试验检测出70种致香物质或潜香物质成分;‘渝金香1号’萜烯类、醛、酮类物质的含量稍低于对照品种‘云烟87’和‘K326’;氮杂环类和酚类物质含量稍高于‘云烟87’和‘K326’;醇类、酯类和酸类物质低于‘云烟87’,高于‘K326’;致香物质占测出致香或潜香物质总量的比例为23.48%,高于‘云烟87’(22.74%)和‘K326’(17.98%),有利于在陈化过程中快速降解生成致香成分;新植二烯与致香物质总量的比例低于‘云烟87’和‘K326’,对于降低烟气的刺激性、协调吃味有利;植物呋喃类含量与新植二烯含量的比例高于‘云烟87’和‘K326’,类胡萝卜素重要致香降解产物总量比‘云烟87’和‘K326’分别高5.92%和5.22%,叶面分泌物降解产物或衍生物总量(34.310 µg/g)高于对照品种‘云烟87’(32.996 µg/g)和‘K326’(32.490 µg/g),有利于彰显‘渝金香1号’烤后烟叶的香气特征。‘渝金香1号’致香物质含量较高,比例较协调,香气质量较好。

| Abstract: | The comparative analysis of the aroma substances’ contents of ‘Yujinxiang No.1’ and the control, ‘Yunyan 87’ and ‘K326’, was carried out to improve the cultivation technologies of ‘Yujinxiang No.1’ and the application of the cultivar in cigarette manufacturing industry. The middle part of tobacco leaves (C3F) of ‘Yujinxiang No.1’, ‘Yunyan 87’ and ‘K326’ in Wushan County of Chongqing were collected, and the aroma substances in leaves were determined by gas chromatography-mass spectrometry. 70 kinds of aroma substances or latent aroma substances were detected in the samples. The contents of terpenoids, aldehydes and ketones in ‘Yujinxiang No.1’ were slightly lower than those in ‘Yunyan 87’ and ‘K326’. The contents of nitrogen heterocycles and phenols were slightly higher than those in ‘Yunyan 87’ and ‘K326’. The contents of alcohols, esters and acids in ‘Yujinxiang No.1’ were lower than those of ‘Yunyan 87’, but higher than those of ‘K326’. The proportion of aroma substances of ‘Yujinxiang No.1’ in the total amount of detected aroma or latent aroma substances was 23.48%, higher than that of ‘Yunyan 87’ (22.74%) and ‘K326’ (17.98%), which was conducive to the rapid degradation and production of aroma substances during aging. The proportion of neophytadiene in ‘Yujinxiang No.1’ to the total amount of aroma substances was lower than that of ‘Yunyan 87’ and ‘K326’, which was beneficial to reducing the irritation of flue gas and coordinating the odor. The ratio of furan compound content to neophytodien content of ‘Yujinxiang No.1’ was higher than that of the control, the amount of aroma substances produced by carotenoids degradation of ‘Yujinxiang No.1’ was 5.92% and 5.22% higher than that of ‘Yunyan 87’ and ‘K326’ respectively, and the amount of leaf exudate degradation products or derivates of ‘Yujinxiang No.1’ was 34.310 µg/g, higher than that of ‘Yunyan 87’ (32.996 µg/g) and ‘K326’ (32.490 µg/g), which was conducive to showing the aroma characteristics of the cultivar. In summary, high content of aroma substances and coordinated chemical composition result in good aroma quality of flue-cured tobacco cultivar ‘Yujinxiang No.1’. |
