摘要
采用涂有聚二甲基硅氧烷-二乙烯苯(PDMS-DVB)涂层的固相微萃取头分别对鲤鱼皮、血、肉的挥发性成分进行萃取,通过气质联用仪分离鉴定,分别检测出20种、23种和19种有效挥发性成分,初步探明了鲤鱼土腥味的组成,为鱼类土腥味的改变或去除提供理论基础。将鲤鱼肉经盐碱水漂洗、香辛料浓缩液浸泡和70℃加热后,经相同的顶空固相微萃取(HS-SPME)和气-质联用仪(GC-MS)条件下检测分析,可有效去除土腥味并增加特有的风味。
In this study,a method for the determination of odours from common carp using headspace solid phase microexWaction （HS-SPME） and gas chromatography-mass spectrometry （GC-MS） was presented.The SPME fiber was coated with PDMS-DVB. Twenty, twenty-three and nineteen effective volatiles were identified separately from common carp skin,common carp blood and common carp meat.The compositions of muddy flavor from common carp were preliminarily definited, which provided a theoretical basis for the change or removal of muddy flavor in fish. Common carp meat was rinsed by saline-alkaline water, immersed by spicy concentratedliquor and heated by low temprature,so muddy fish odour of common carp could be removed effectively .That was demonslrated by HS-SPME/GC-MS in the same condition.
