The quality of burley leaf tobacco was affected by various toasting conditions. In this study, we determined main factor to influence the quality of burley tobacco on toasting and established proper toasting condition to improve the quality of toasted tobacco. Our results indicated that the main factor to influence the quality of burley tobacco was the amount of treatment and 3rd drying zone temperature. We also found that the proper toasting conditions to improve the quality of toasted tobacco and reduce the smoking irritation were moisture content (34 %), amount of treatment (1,520kg/hr), 1st drying zone temperature (135$^{\circ}C$), 2nd zone drying temperature(145$^{\circ}C$) and 3rd zone drying temperature (147$^{\circ}C$).

The optimal condition was investigated to make for good quality of Burley tobacco during the toasting. A complete factorial design (3$\times$3) and rotatable central composite design were used in this study. Based on the results obtained, it would be possible that 1) methyl-pyrazine other than pyrazine compounds is assumed to play an important role in the improvement of smoke taste. 2) filling value of Burley 21 leaf can be increased by 5~10 % 3) fragility index can be increased by about 5%. 4) total volatile base can also be reduced by about 10% and 5) the aroma and favorable taste of the Burley tobacco can be Improved by toe optimization the amount of sugar added and the toasting time and temperature.
