GC/MS analysis of oxidative degradation of lutein and its flavoring application in cigarette

Chemistry method was used to oxidate degradation of lutein,and the products of degradation were analysed by GC/MS.The results indicated that the oxidative degradation of lutein was respectively determined 6,12 and 17 kinds of compounds under the effection of H₂O₂,AgNO₃ and KMnO₄,by using 95% ethanol as solvent.Common components had dihydroactionlide,3-oxygen violet alcohol,isophorone and so on among them and the content of dihydroactionlide was relative higher.The degradation products of lutein were applied in unblended cut tobacco and cut filler.The results indicated that adding the suitable amount of degradation products of lutein could efficiently improve smoking quality of the cigarettes,increase quantity of tobacco aroma,reduce offensive odor and irritation and amend aftertaste.The rational consumption was 0.01%.
