| Abstract: |
| In order to investigate the variation of aroma components in cut tobacco in the heating and humidifying process(SIROX process) and drying process on primary processing line,samples were collected on the primary processing line at three time points:before SIROX,after SIROX(before drying) and after drying.Samples were ultrasonically extracted with solvent,then analyzed by GC-MS and quantified with C17 as internal standard.Results showed that:Firstly,the contents of 18 aroma components such as acetic acid and benzyl alcohol,etc.decreased during SIROX process,while those of 6 aroma components increased,including 2-furanmethanol,2,4-dihydroxy-2,5-dimethyl-3(2H)-furan-3-one,etc.Secondly,the contents of 14 aroma components such as acetic acid and maltol,etc.decreased during drying process,while those of 6 aroma components increased,including 2-furanmethanol and 2-furancarboxaldehyde,etc.Thirdly,the contents of 23 aroma components such as acetic acid and 2,3-butanediol,etc.decreased during SIROX and drying process,while those of 4 aroma components increased，including 2-furanmethanol and 2,4-dihydroxy-2,5-dimethyl-3(2H)-furan-3-one,etc.Fourthly,the variations of temperature and humility in SIROX and drying process on primary processing line may result in Maillard reaction,degradation and volatilization inside the cut tobacco,leading to the changes of the aroma components.This investigation provides a scientific basis for the development of cigarette products with high quality. |
