Abstract：Degradation of carotenoids in discarded tobacco leaves by biological and physical treatments was investigated.Biological treatment was to isolate a strain to effectively degrade β-carotene and this strain was identified a yeast Trichosporon.GC-MS analysis showed that this yeast could completely degrade β-caro-tene.The physical method was to treat discarded tobacco leaves by ozone.GC-MS analysis showed that the contents of carotenoid and chlorophyll increased during the processing time firstly,then decreased and be-came stable.Moreover,after ozone treatment,the contents of alcohols,esters and ketones in tobacco were raised,and the content of nicotine,neophytadiene and carbon stearic acid were reduced to mellow tobacco aroma and reduce irritancy.
