摘　　要：分别采用在空气环境和充氮低氧环境中解封在密封低氧贮存环境下醇化的烟叶,研究解封过程对烟叶中化学成分的影响.以气相色谱/质谱联用和高效液相色谱为检测方法,考察挥发性致香成分、类胡萝卜素、烟草生物碱和氨基酸含量的变化.结果表明,采用充氮低氧方法的烟叶,其前体中的类胡萝卜素、烟草生物碱和氨基酸的含量在4周内的含量与解封时基本保持一致,而部分挥发性致香成分则会出现明显上升.空气中解封的方法,前体中的部分烟草生物碱和氨基酸含量会略微发生变化,但挥发性致香成分则保持平稳,含量基本没有变化.研究结果可以为烟叶解封后确定合理的储存期限和环境提供参考.Aging tobacco leaves in sealed and oxygen-reduced environment were unsealed in an air environment and a nitrogen-filled low-oxygen environment respectively to study the impact of the unsealing process on the chemical components of the tobacco leaves.Gas chromatographymass spectrometry(GC-MS)and high-performance liquid chromatography(HPLC)were used as detection methods to examine changes in the contents of volatile aroma components,carotenoids,nicotine and amino acids.The results show that the contents of carotenoids,nicotine and amino acids in the precursors of tobacco leaves unsealed in a nitrogen-filled low-oxygen environment remain basically the same as the initial content within one month,and some volatile aroma components would increase significantly.When unsealed in the air,the content of some nicotine and amino acids in the precursor will change slightly,but the volatile aroma components will remain stable and basically unchanged.The results of this study can provide a reference for determining a reasonable storage period and environment after tobacco leaves are unsealed.
