复烤烟叶挥发性香味成分同时蒸馏萃取的优化研究

为明确打叶复烤后烟叶挥发性香味成分含量,对其挥发性香味成分同时蒸馏萃取条件进行了优化研究,考查了同时蒸馏萃取溶剂不同厂家CH2Cl2、料液比、蒸馏时间、NaCl用量、CH2Cl2体积、水浴温度等因素对结果的影响,通过均匀试验设计分析法优化试验条件。结果表明,选用Dikma CH2Cl2的总离子流色谱图在40 min左右有少量的杂质峰,对挥发性成分无较大影响,去离子水体积为350 mL,蒸馏时间为3.0 h,NaCl用量为30 g,CH2Cl2体积为60 m L,水浴温度为60℃,该方法为复烤后烟叶挥发性香味成分含量提供支撑。

Optimization of Simultaneous Distillation Extraction of Volatile Flavor Components in Flue-cured Tobacco Leaves After Threshing and Redrying

In order to determine the content of volatile aroma components in flue-cured tobacco leaves after threshing and redrying,the conditions of simultaneous distillation and extraction of volatile aroma components were optimized,the influences of the factors such as CH2Cl2,the ratio of material to liquid,the time of distillation,the amount of NaCl,the volume of CH2Cl2 and the temperature of water bath on the analysis results were investigated.The results showed that the total ion current chromatogram of Dikma CH2Cl2 had a small amount of impurity peaks about 40 min,and had no significant effect on the volatile components,deionized water volume was 350 m L,distillation time was 3.0 h,NaCl mass was 30 g,CH2Cl2 volume was 60 mL,water bath temperature was 60℃.This method provided support for the content of volatile aroma components in recured tobacco leaves.
