复烤片烟在不同醇化环境中的质量变化

Quality Changes of Redried Tobacco Strips Aged in Different Environments

探究相同复烤片烟在不同醇化环境中自然醇化进程及烟叶醇化质量的变化和差异,为复烤片烟进行合理异地醇化提供理论依据。将福建南平K326复烤片烟分别存贮于河南新郑和福建武夷醇化库进行自然醇化,分析不同醇化环境中片烟化学成分、外观质量和感官质量的变化。结果表明,随着醇化的进行,河南新郑醇化库和福建武夷醇化库醇化片烟的还原糖、总糖、总氮和烟碱均呈下降趋势,与未醇化时相比,醇化24个月时,河南新郑醇化库片烟中总糖和还原糖含量分别降低12.74%和9.31%;福建武夷醇化库片烟中总糖和还原糖含量分别降低15.58%和12.56%。在整个醇化期,河南新郑醇化库片烟中总糖和还原糖含量均高于福建武夷醇化库,两醇化库片烟中总氮、烟碱含量均无显著差异。随着醇化的进行,两醇化库片烟中叶黄素、β-胡萝卜素、新绿原酸、隐绿原酸、绿原酸、莨菪亭、山奈酚-3-芸香糖苷和芸香苷含量均呈降低趋势,福建武夷醇化库片烟中多酚类物质降解幅度高于河南新郑醇化库。在相同醇化时间,福建武夷醇化库醇化的片烟外观质量均优于河南新郑醇化库醇化的片烟。两醇化库片烟的感官质量评吸得分均表现为先上升后下降的变化趋势,河南新郑醇化库和福建武夷醇化库片烟的感官质量分别在醇化16个月和12个月时达到最佳,福建武夷醇化片烟的最佳醇化状态较河南新郑醇化片烟提前4个月。福建武夷醇化的片烟感官质量评吸得分均高于同期河南新郑醇化片烟的感官质量评吸得分,且在醇化后期感官质量得分降低速率较慢,保质效果更好。总之,与河南新郑醇化库相比,在福建武夷醇化库进行醇化的片烟具有醇化时间短、品质佳、保质期长的优点。

This study explored the changes and differences in natural aging process and quality of redried tobacco strips aged under different storing conditions,to provide theoretical basis for the rational aging of redried tobacco strips under different storage conditions.The tobacco strips of tobacco cultivar K326 produced in Nanping,Fujian Province were stored in Xinzheng warehouse,Henan Province and Wuyi warehouse,Fujian Province for natural aging.The dynamic changes of chemical contents,appearance quality and sensory quality of redried tobacco strips were analyzed.The results showed that the contents of reducing sugar,total sugar,total nitrogen and nicotine in both aging warehouses all decreased with the aging time.Compared with unaged,the total sugar and reducing sugar contents of redried tobacco strips stored in Xinzheng at the 24th month decreased by 12.74%and 9.31%respectively,and stored in Wuyi decreased by 15.58%and 12.56%.During the whole aging period,the total sugar and reducing sugar contents of redried tobacco strips stored in Xinzheng were higher than those of redried tobacco strips stored in Wuyi.There were no significant differences in the total nitrogen and nicotine contents between the two aging warehouses.The contents of lutein,β-carotene,neochlorogenic acid,4-dicaffeoylquinic acid,chlorogenic acid,scopoletin,kaempferol 3-rutinoside and rutin all decreased with the aging time.The degradation rate of polyphenols in redried tobacco strips stored in Wuyi was higher than that stored in Xinzheng.At the same aging time,the appearance quality of tobacco strips stored in Wuyi was better than that of tobacco strips stored in Xinzheng.The sensory quality score showed the trend of rising first and falling later.The sensory quality of redried tobacco strips aged in Wuyi and Xinzheng warehouses reached the best at the 12th and 16th months,respectively.The sensory quality evaluation score of tobacco strips stored in Wuyi warehouse was higher than that of tobacco strips stored in Xinzheng warehouse in the same aging period.Compared with tobacco strips stored in Xinzheng warehouse,the sensory quality reduction rate of tobacco strips stored in Wuyi warehouse was slower in the latter stage,and the quality preservation effect was better.In conclusion,compared with Xinzheng warehouse,the redried tobacco strips stored in Wuyi warehouse had the advantages of shorter aging time,better quality and longer high quality period.
