Effects of Storage Methods and Time on Aging Quality of Tobacco Leaves
摘要
Abstract
[Objective]The influences of different storage methods and time on the aging quality of tobacco leaves were explored to provide the theoretical basis for the classified storage of tobacco leaves and the implementation of precise maintenance measures.[Method]Fujian Longyan CFS tobacco leaves and Guizhou Zunyi CFSE1 tobacco leaves with five aging times(3 months,9 months,12 months,15 months and 18 months)were selected from the natural repository,moisture repository and mechanical repository,respectively.The varieties were Yunyan 87.The conventional chemical components and volatile components of tobacco leaves were determined by continuous flow instrument and GC-MS technology,and the aging quality of tobacco leaves under different storage conditions was explored by principal component analysis.[Result]During the aging process,the nicotine,total sugar and reducing sugar contents of the two kinds of tobacco leaves in different storage repositories showed a decreasing trend.Among them,after 18 months of aging,the nicotine,reducing sugar and total sugar contents of Fujian Longyan CFS tobacco leaves in the three storage repositories decreased by 23.13%-16.79%,18.82%-16.27%and 19.14%-13.33%respectively,compared with those at the three months of aging.The nicotine,reducing sugar and total sugar contents of Fujian Longyan CFS tobacco leaves in the mechanical storage repository decreased the most.At 18 months of aging,the nicotine content of Guizhou Zunyi CFSE1 tobacco leaves in mechanical repository,natural repository and moisture repository decreased by 4.55%,10.13%and 6.58%respectively,compared with that at 3 months of aging,and the reducing sugar decreased by 7.37%,4.49%and 12.23%,respectively,while the total sugar decreased by 7.25%,9.96%and 13.30%,respectively.After 18 months of aging,the conventional chemical composition content and sugar-nicotine ratio of Fujian Longyan tobacco leaves in the three storage repositories were within the appropriate range,while the reducing sugar,total sugar content and sugar-nicotine ratio of Guizhou Zunyi tobacco leaves were not within the appropriate range,so the aging time should be extended.The total volatile components of the two kinds of tobacco leaves in the three storage repositories increased with the aging time,and the highest value was found in the mechanical repository after 18 months of aging.The results of principal component analysis showed that the storage repositories had a significant impact on the volatile components of the two kinds of tobacco leaves.[Conclusion]After 18 months of aging,the total volatile components of Fujian Longyan CFS tobacco leaves and Guizhou Zunyi CFSE1 tobacco leaves are the highest in the mechanical repository,and the conventional chemical components content and sugar-nicotine ratio of Fujian Longyan CFS tobacco leaves are appropriate.Considering the content of conventional chemical components and total volatile components of tobacco leaves,Fujian Longyan CFS tobacco leaves and Guizhou Zunyi CFSE1 tobacco leaves should be stored in the mechanical repository.关键词
