Abstract: The Effects of different temperature and humidity yellowing conditions on the aroma constituents of tobacco leaves during bulk curing were studied using the electric-heated flue-curing barn designed and made by Henan Agricul-ture University.The result showed that the treatment of low temperature and medium humidity yellowing condition(dry-bulb temperature 38℃ and relat ive humidity 85%-80%)could increase the contents of acids and neutral aroma constituents.The contents of oxalic acid,malic acid and noctadecanoic acid,which contributed importantly to the fragrance of tobacco leaves,were increased remarkably,and the total contents of neutral aroma const ituents including the benzyl alcohol,phenyl acetaldehyde,phenyl ethyl alcohol,furfural,furfuryl alcohol,acepyrrol,B-damascenone,geranyl acetone,dihy-droactinolide,megastigmatrienoneⅡ,megastigmatrienoneⅣ,3-hydrogen-B-damascone and solanone were also increased to a certain degree.

Key words: Flue-cured tobacco, Bulk curing, Temperature and humidity, Aroma constituents
