| 目的 研究食品包装材料常用的5种粘合剂样品中的挥发性成分。方法 采用顶空固相微萃取法（HS-SPME） 提取粘合剂中的挥发性化合物， 再利用气相色谱质谱联用技术 （GC-MS） 结合气相色谱嗅觉测量法 （GC-O）， 分析计算挥发性化合物的保留指数、 量化强度值、 气味和浓度， 鉴定粘合剂中的主要挥发性化合物， 并对挥发性组分及浓度进行定性、 定量和对比分析。结果 采用HS-SPME/GC-O-MS法能有效地鉴别和确认粘合剂中挥发性化合物的类别及浓度； 各粘合剂的挥发性气味成分在组成和含量上存在差异， 粘合剂中有33种嗅感物质， 其中乙酸、 丁酸、 丁酸甲酯、 1-丁醇和壬醛存在于大部分的粘合剂。结论 粘合剂中含量最丰富的挥发性化合物是乙酸， 其含量范围为22 900～8 930 000 ng/g， 最佳的萃取纤维时间为15 min， 最优萃取纤维是DVB/CAR/ PDMS。 |
| 英文摘要: |
| The volatile compounds in five adhesives used in food packaging materials were studied. The volatile compounds in adhesives were extracted by head space solid-phase microextractions (HS-SPME) firstly. Then the retention index, odor, quantitative values and concentration of volatile compounds identified were calculated by gas chromatography and mass spectrometry (GC-MS) and gas chromatography-olfactometry (GC-O). The major volatile compounds in adhesives were identified and the compositions and concentrations of the volatile compounds were qualified, quantified and compared. The results showed that the type and the concentration of volatile compounds can be effectively identified and confirmed by HS-SPME/GC-O-MS. And the volatile components for each adhesive were different in composition and content. Totally 33 kinds of odors were identified, among which in most adhesives were acetic acid, butyric acid, methyl butyrate, 1-butanol, and nonyl aldehyde. The most abundant volatile compound in adhesives was acetic acid, whose concentration varied from 22 900~8 930 000 ng/g. The optimum extraction time was 15 minutes and the proper extraction fiber was DVB/CAR/PDMS. |
