Eleven odorants were identified or tentatively identified from the twelve peaks as methional, (E,Z)-2,6-nonadienal, (E)-2-nonenal, (E,E)-2,4-nonadienal, (E,E,Z)-2,4,6-nonatrienal, trans-4,5-epoxy-(E)-2-decenal, 4-hydroxy-2,5-dimethyl-3(2H)-furanone, 3-hydroxy-4,5-dimethyl-2(5H)-furanone, isovaleric acid, methyl anthranirate, and vanillin. The FD factors of the odor-active peaks in dried mat rush were observed
通过将溶剂萃取与溶剂辅助风味蒸发(SAFE)技术相结合,制得草席(igusa)香精。对挥发性成分进行的香精提取物稀释分析(AEDA)显示了51个气味活性峰,FD因子在4(3)和4(7)之间。在感知到的增香剂中,十二个峰具有较高的FD因子(>或= 4(6))被证明是草皮草特有香气的最重要组成部分。从十二个峰中鉴定出或初步鉴定出11种气味剂,分别为(甲,(E,Z)-2,6-壬二烯醛,(E)-2-壬烯醛,(E,E)-2,4-壬二烯醛(E,E) ,Z)-2,4,6-非芳基,反式-4,5-环氧-(E)-2-癸烯,4-羟基-2,5-二甲基-3(2H)-呋喃酮,3-羟基-4 ,5-二甲基-2(5H)-呋喃酮,异戊酸,邻氨基苯甲酸甲酯和香草醛。观察到干燥的草席草丛中气味活性峰的FD因子比原始的草席草丛中的气味因子峰高得多。这一发现表明,草席草制造过程中的干燥过程是形成特征草席草香气的最重要因素之一。
