摘要
异嗅异味关系到人们生活的方方面面,由于可产生异味的物质种类繁多,且通常在较低浓度下即可产生异味,因此异味物质仪器分析对仪器灵敏度、选择性以及分析目标化合物的范围有很高要求。本文利用固相微萃取(SPME)提取浓缩食品包装纸样品中的易挥发物质,利用系统配置的数据库在三重四极杆气质联用仪上建立多反应监测方法进行分析,方法可给出定性与初步定量结果。结果发现:在异味包装纸样品中所确定的引起异味的目标化合物含量明显高于正常包装纸。说明本文所采用SPME-GC-MS/MS法分析,拥有更高的灵敏度和选择性,系统提供的数据库中不仅有方便定性、定量的方法与必要资料,而且包括了150种目标化合物气味阈值和气味描述等信息,利于异味的解析。
Off-flavor compounds analysis is an important subject which effects many aspects of people's life. Because there are many compounds which can cause off-flavor in very low concentration level, the sensitivity, selectivity and range of target compounds cover are very important for off-flavor analysis. In this paper, the off-flavor compounds in food packing paper were extracted with SPME and analyzed by triple quadrupole GCMS with MRM acquisition method,which was created with the database of the system. Then the method gave the qualitative and semiquantitative results. The results showed the amounts of several off-flavor compounds in odor-abnormal sample were higher than in odor- normal sample. It illustrates SPME-GC-MS/MS can offer high sensitivity and selectivity in off-flavor analysis. The database provided by the system not only has the qualitative and quantitative analytical methods and essential data, but also includes odor threshold values and characteristic odor descriptions of 150 off-flavor compounds which may necessary for further off-flavor analysis.
