摘　　要：目的采用顶空固相微萃取技术(HS-SPME)结合气质联用(GC-MS)技术分析5款包装印刷品中对气味贡献较大的成分。方法通过考察不同类型的萃取头、平衡时间、萃取时间和萃取温度对挥发性/半挥发性成分的数量及含量的影响,建立一种包装印刷品气味成分检测方法。结合解卷积+匹配度法+保留指数法对检测出的化合物进行定性识别,通过归一化法和内标法对气味成分的含量进行分析,并结合化合物的气味阈值,筛选关键气味成分。结果得到了最佳的分析条件,采用50/30μm聚二乙烯苯/碳分子筛/聚二甲基硅氧烷固相微萃取头,平衡时间为30 min,萃取时间为30 min,萃取温度为80℃,解吸时间为10 min。在上述最优条件下,5款包装印刷品被鉴别出43种关键性气味成分,包括醛类、酮类、醇类、芳香烃类、杂环类、酯类、醚类、胺类等八大类。结论该方法可为后续包装印刷品气味分析、异味预警、新产品开发、工艺技术改进等提供技术支撑。The work aims to analyze the five packaging printing by headspace solid phase microextraction(HS-SPME)combined with gas chromatography-mass spectrometry(GC-MS)to determine the principal odor components.The determination method was established by investigating the effect of different types of extraction head,equilibrium time,extraction time and extraction temperature on the quantity and content of volatile/semi volatile components.To identify the detected compounds,deconvolution,matching and retention index method were utilized.The content of odor components was analyzed by peak area normalization method and internal standard method.Combined with the odor threshold of compounds,the principal odor components were screened.The optimal extraction efficiency was achieved under the following conditions,50/30μm divinylbenzene/carboxen/polydimethylsiloxane SPME fiber,equilibrium for 30 min,extraction for 30 min at 80℃ and desorption for 10 min.Under the above conditions,43 compounds of five packaging printing were identified as principal odor components.These compounds included aldehydes,ketones,alcohols,aromatic hydrocarbons,heterocycles,esters,ethers,amines.This method provides technical support for odor analysis,odor warning,new product development and differential changes after technological improvement in packaging printing products.
