叶黄素氧化降解产物GC/MS分析及在卷烟加香中的应用

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

采用化学法对叶黄素进行氧化降解,产物用GC/MS进行检测.结果表明:以95%乙醇作溶剂,叶黄素在H2O2,AgNO3,KMnO4作用下,氧化降解生成的产物分别确定出6种、12种、17种化合物,共有的成分有二氢猕猴桃内酯、3-氧代紫罗兰酮、异佛尔酮等,并均以二氢猕猴桃内酯相对含量最高.加香试验结果表明:在烤烟中添加适宜浓度的叶黄素降解产物对感官质量有显著的改善作用,可以增补烟香,减轻杂气和刺激性,改善吃味;较为合适的用量为0.01%.

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%.
