摘　　要：[Objectives] This study was conducted to compare the effects of different curing processes,in order to optimize the local supporting intensive fluecuring process.[Methods] A comparative experiment was carried out in Mile,Luxi and Jianshui on the four-layer tobacco-packed intensive curing process(K1)and the eight-point precise and intensive curing process(K2).[Results]The results showed that according to the appearance evaluation of the tobacco leaves,K1 was higher than K2 in respective scores of color,maturity,leaf structure and defects and the total score,while K1 equaled K2 in the scores of identity,oil content,chroma and length.The differences in respective scores of the two processes were not significant.According to the results of sensory evaluation,the two tobacco enterprises got different evaluation results of unblended cigarettes made of the middle leaves due to different raw material requirements of the enterprises by different processes.K1 was higher than K2 in the sensory evaluation of China Tobacco Yunnan Industrial Co.,Ltd.,while it was lower than K2 in that of China Tobacco Zhejiang Industrial Co.,Ltd.,and the difference in the total score between the two processes was significant.From the content of chemical components,in the conventional chemical component contents including total sugar,reducing sugar,chlorine and starch,K1 was higher than K2,while in the contents of potassium,total phytonine,total nitrogen and petroleum ether extract,K1 was lower than K2,but the differences were not significant.K1 was lower than K2 in the contents of neutral aroma components including ketones,alcohols,aldehydes,heterocyclics,neophytadiene and total content,while K1 was higher than K2 in the contents of esters,phenols,but the respective differences were not significant.Except the significant difference in the total score in the sensory evaluation of China Tobacco Zhejiang Industrial Co.,Ltd.,there were no significant differences in other items in the appearance evaluation,sensory evaluation and chemical compositio[Objectives] This study was conducted to compare the effects of different curing processes,in order to optimize the local supporting intensive fluecuring process. [Methods] A comparative experiment was carried out in Mile,Luxi and Jianshui on the four-layer tobacco-packed intensive curing process（ K1）and the eight-point precise and intensive curing process（ K2）. [Results]The results showed that according to the appearance evaluation of the tobacco leaves,K1 was higher than K2 in respective scores of color,maturity,leaf structure and defects and the total score,while K1 equaled K2 in the scores of identity,oil content,chroma and length.
