摘要
为优化红大烟叶净油的超临界CO2萃取工艺条件,采用L9(34)正交试验法对红大烟叶净油的提取率进行了考察,并对其进行了气相色谱-质谱鉴定。结果表明:最佳萃取条件为萃取压力30 MPa,萃取温度45℃,CO2流量25 kg/h,萃取时间2.0 h;共鉴定出36种化学成分,其中含量较高的成分主要有12-异丙基-1,5,9-三甲基-4,8,13-环十四碳三烯-1,3-二醇(21.28%)、烟碱(15.88%)、十八炔(6.70%)、2,5-环氧二氢紫罗兰酮(4.49%)、喇叭茶醇(3.59%)、1-甲基-4-(2-甲基环氧乙烷基)-7-氧杂双环[4.1.0]庚烷(2.42%)、阿斯利多(2.32%)、苯胺(2.20%)、4H-环戊[DEF]菲(2.00%)等。该净油能提升烟草本身香气,使烟香丰满飘逸,并能赋予卷烟独特的风格特征,可明显增加卷烟的抽吸品质。优选得到的工艺可提高红大烟叶净油提取率,工艺稳定、可行。
In order to optimize the supercritical CO2 extraction conditions for Hongda tobacco essence,the extraction yield was investigated by L9（34） orthogonal experiment,and the volatile components in the obtained extracts were analyzed by GC/MS,and the essence was applied into cigarette as a flavor.The results of the experiments indicated that the optimal extraction pressure,temperature,CO2 flow rate and time were 30 MPa,45 ℃,25 kg/h and 2.0 hours,respectively.Thirty-six components were identified,and the main volatile components were： 12isopropyl-1,5,9-trimethyl-4,8,13-cyclotetradecatriene-1,3-diol（21.28%）,nicotine（15.88%）,octadecyne（6.70%）,2,5-epoxydihydroretroionone（4.49%）,ledol（3.59%）,1-methyl-4-（2-methyloxiranyl）-7-oxabicycloheptane（2.42%）,ascaridole（2.32%）,benzenamine（2.20%）,4H-cyclopentaphenanthrene（2.00%）.The sensory evaluation showed that the essence obviously enhanced tobacco＇s natural aroma,and imparted a unique stylish character to tobacco.The optimized parameters increase the yield of essence,and the extraction process is feasible and stable.
