The discarded tobacco extracted by supercritical CO₂ was separated by molecular distillation techniques and analyzed by GC-MS. Fifty-two kinds of compounds were identified in total. 15 kinds of compounds were identified by the 80℃ light fraction. Among them,heterocycles were dominant,accounting for 98.91% of the total,followed by esters(0.606%). Twenty-six kinds of compounds were identified by the 120℃ light fraction. The chemical classes were mainly made up of heterocycles(91.42%),with relatively small amounts of ketones(4.16%),alcohols(2.87%) and hydrocarbons(0.74%). There were 26 kinds of compounds identified by the 160℃ light fraction. Alcohols(67.97%) were the dominant chemicals,followed by heterocycles(11.57%),hydrocarbons(7.9%),ethers(4.09%),ketones(3.77%),esters(2.80%) and aldehydes(1.89%),respectively. There were obvious differences in the compound types and contents of different fractions,which reflected the selective enrichment feature of molecular distillation. The sensory evaluation of the mixture of the 80℃ and 120℃ light fraction with the mass ratio of 8:2 was better. The sample's aroma quantity and quality increased,the after taste got more comfortable. Meanwhile it presented sweet aroma and more pure smoke flavor.
