1、云南新鲜松露和干制松露挥发性风味成分的对比分析冯涛1,水梦竹1,宋诗清1,余跃先2,孙敏1,徐志民3(1.上海应用技术大学香料香精技术与工程学院,上海201418;2.云南南华县咪依噜天然食品开发有限责任公司,云南南华675200;3.美国路易斯安那州立大学食品科学系,路易斯安那巴吞鲁日70802)摘要:采用顶空固相微萃取(HS-SPME)法萃取云南新鲜采摘黑松露和真空冷冻干燥黑松露中的挥发性成分,利用气相色谱-质谱联用仪(GC-MS)和气相色谱-火焰光度检测器(GC-FPD)对挥发性成分和含硫物质进行鉴定。结果表明,新鲜黑松露和干制松露中分别鉴定出30种和
2、83种挥发性风味物质,8种和19种含硫化合物。1-辛烯-3-醇,对甲酚甲醚,3-甲基丁醛,二烯丙基二硫醚和二甲基硫醚在新鲜松露中的含量较高;对甲酚甲醚,己酸,右旋柠檬烯,二甲基砜,烯丙基甲基三硫醚在干制松露中含量较高。气相色谱-嗅闻(GC-O)结合香气活力值(OAV)发现,新鲜松露中二烯丙基二硫醚,二甲基硫醚,1-辛烯-3-酮,3-甲基丁醛对香气贡献较大;干制松露中双(2-甲基-3-呋喃基)二硫醚,丙位壬内酯,己酸,1-辛烯-3-酮,对伞花烃贡献较大。关键词:云南松露;风味;顶空固相微萃取(HS-SPME);气相色谱-质谱联用仪(GC-MS);气相色谱-火焰
