摘要
采用水蒸气蒸馏法提取白灵菇中风味成分,然后利用气相色谱-质谱(GC-MS)联用技术进行分析,得到白灵菇总离子流色谱图中共75个峰,经过NIST谱库联机检索,鉴定出35种化合物,约占色谱流峰总面积的79.75%。结果表明,白灵菇风味成分中含量最多的一类化合物为胺类化合物,相对百分含量为43.19%。在胺类化合物中(Z)-9-十八烯酰胺含量最高,相对含量为22.47%。
The flavor compounds of Pleurotus ferulae were extracted by steam distillation extraction.It was found that there were 75 peaks in the total ion current chromatographic chart of Pleurotus ferulae by GC-MS analysis.By NIST spectrum library online retrieval,the 35 compounds were identified from the flavor compounds,and they were 79.75% of the total chromato-graphic peak area.The results showed that the contents of the amine compounds were the most among all the flavor compounds of Pleurotus ferulae,and its re...
