不同辐照方式的红参酒挥发性成分GC-MS分析

GC-MS Analysis of Volatile Components of Red Ginseng Liquor with Different Irradiation Methods

采用电子束和60Co-辐照的方法对红参浸泡酒进行辐照,采用顶空固相微萃取法提取红参酒中挥发性成分,并用气相色谱-质谱法进行分析。分别在原红参酒、电子束辐照酒、60Co-辐照酒中鉴定出24、37、24种挥发性物质,其中萜烯类化合物是3种红参酒的主要挥发性成分,电子束辐照对红参酒的挥发性成分的种类及含量有显著影响。3种红参酒中共同挥发性成分有8种,主要有-古芸烯、-人参烯、-榄香烯、马兜铃烯、香树烯、-芹子烯;电子束辐照酒有15种特有挥发性成分,主要有丁香烯、-古芸烯、1,2,4-三乙苯、异丙基苯甲酰胺;60Co-辐照酒有7种特有挥发性成分,主要有-杜松萜烯、六甲苯、5-羟基-3-甲基-1-茚酮。本研究分析辐照前、后红参酒挥发成分的变化,旨在为红参酒催陈工艺提供参考。

The volatile components in red ginseng liquor were extracted by headspace solid phase microextraction and analyzed by gas chromatography-mass spectrometry.We identified 24 kinds of volatile substances in original liquor,37 kinds in electron beam irradiation liquor,24 kinds in 60Co-irradiation liquor.Terpene compounds were the main volatile components of 3 kinds of red ginseng liquor,electron beam irradiation has a significant effect on the kinds and contents of volatile components in red ginseng liquor.There were 8 kinds of common volatile components in red ginseng liquor,mainly-gurjunene,-panasinsene,-elemene,aristolene,alloaromaderene,-selinene;electron beam irradiated liquor had 15 unique volatile components,mainly caryophyllene,-gurjunene,1,2,4-triethylbenzene,isopropylbenzamidine;60Co-irradiated liquor had 7 unique volatile components,mainly-cadinen,hexamethylbenzene,5-methyl-3-hydroxy-1-indanone.In this study,changes of volatile components in red ginseng liquor before and after irradiation were analyzed in order to provide references for the aging process of red ginseng liquor.
