浓香葵花籽油气味活性物质的HS-SPME 萃取条件优化及GC-O-MS分析Optimization of HS-SPME and identification of aroma-active substances in fragrant sunflower seed oil by GC-O-MS
为了提高浓香葵花籽油风味物质的萃取效果及对其气味活性物质进行鉴定,对顶空固相微萃取(HS-SPME)的萃取条件进行优化,并结合气相色谱-嗅闻-质谱技术(GC-O-MS)对浓香葵花籽油的气味活性物质进行分离和鉴定。结果表明,HS-SPME萃取浓香葵花籽油的最佳条件为样品3 g,DVB/CAR/PDMS萃取头长度2 cm,萃取温度70 ℃,萃取时间50 min。通过GC-O-MS分析,在浓香葵花籽油(160 ℃烘烤葵花籽仁25 min)中共鉴定出63种挥发性物质,其中12种具有气味活性,包括4种吡嗪类(烤香味和坚果味)、2种呋喃类(焦糖味和甜香味)、4种醛类(生青味、果香和油脂味)、1-辛烯-3-...
