基于GC-MS对皮革特征气味的分析与模拟

Leather Odors Analysis by GC-MS and Simulation

采用索氏提取法对不同种类皮革中的挥发性成分进行提取,结合气相色谱-质谱联用技术(GC-MS)分析其挥发性物质的主要组成。根据GC-MS测定结果,通过感官分析模拟具有皮革特征气味的香精。结果表明:未涂饰羊服装革、涂饰羊服装革、涂饰牛服装革和涂饰牛汽车坐垫革的特征气味中,挥发性物质种类繁多,包含烃类、酯类、醛类、酸类、醚类和酮类化合物,以烃类物质为主。根据GC-MS分析结果,结合调香实践经验,调配出香气饱满、逼真、协调的皮革特征气味的香精。

The volatile organic components of different leathers were extracted by Soxhlet extraction and determined with gas chromatography and mass spectrometry （ GC - MS）. The leather fragrance was simulated by the sensor analysis based on the GC - MS results. The results show that there are many volatile organic components in the ordour of the unfinished arid finished sheep garment leathers, cow garment leather and cow ear seat leather. These components are hydrocarbons, esters, aldehydes, acids, aethers and ketones, etc. Based on the GC - MS results, the leather fragrance is further prepared.
