THE COMPARISONS OF VOLATILE OILS OF FLUE-CURED TOBACCO PRODUCED IN KOREA AND IN THE UNITED STATES

Generally, the same quality tobacco may give similar concentration of each chemical component. This research investigation was studied to obtain the differences in concentrations of volatile oil compounds in physically similar tobacco produced in different environment and managements-in Korea and in the United States. The flue-cured leaf tobacco produced in Korea and America was regraded to B3L and P3L by American grading system and analyzed for volatile oils relating to tobacco flavor and aroma. Sixty compounds of the more than 100 peaks distinguishable on the total neutral volatile oils were identified by G5-MS and quantified. Their concentrations are compared between B3 L and P3L produced in Korea and in the United States. The most volatile oil concentrations of B3 L and P3L grade tobacco arc higher in American than in Korean. Only a few components such as benzaldehyde, pulegonc, 4, 6, 9 - megastigmatriene - 3 - one, and coumaran are less in American.
