摘　　要：为研究池塘和稻田养殖模式对全州禾花鲤(Cyprinus carpio var. Quanzhounensis)风味物质的影响,采用顶空固相微萃取法检测全州禾花鲤肌肉和肝胰腺中的E-2-壬烯醛、2-甲基异茨醇(2-MIB)和土臭素(GSM)的含量,以及利用高效液相色谱串联质谱仪检测次黄嘌呤核苷酸(IMP)的含量,并进行比较分析。结果显示,在土腥味物质方面,稻田养殖模式下禾花鲤肌肉的2-MIB和GSM含量极显著高于池塘养殖模式,肝胰腺的E-2-壬烯醛和GSM含量极显著高于池塘养殖模式(P<0.01);在鲜味物质方面,稻田养殖模式下禾花鲤肌肉的IMP含量极显著高于池塘养殖模式(P<0.01),肝胰腺的IMP含量不存在显著差异(P>0.05)。综上所述,稻田养殖的全州禾花鲤鲜味更高,但土腥味更重;池塘养殖的全州禾花鲤土腥味淡,但鲜味不浓。In order to study the effect of pond and paddy field cultivation mode on the flavor substances of C.carpio var.Quanzhouensis,headspace solid phase microextraction method was used to detect the contents of E-2-nonenal,2-methylisothiol(2-MIB),and geosmin(GSM)in muscles and hepatopancreas.The content of hypoxanthine nucleotides(IMP)was determined by high performance liquid chromatography tandem mass spectrometry.The results showed that in terms of earthy smell substances,the contents of 2-methylisoalloxal and geosmin in the muscle of C.carpio var.Quanzhouensis cultured in paddy fields were extremely significantly higher than those in pond cultivation mode,and the contents of e-2-nonenal and geosmin in the hepatopancreas of C.carpio var.Quanzhouensis cultured in paddy fields were extremely higher than those in pond cultivation mode(P<0.01).In terms of umami substances,IMP contents in the muscles of C.carpio var.Quanzhouensis cultured in paddy fields were extremely higher than those of Cyprinus carpio var.Quanzhouensis cultured in ponds(P<0.01);no significant differences were found in the IMP content of the hepatopancreas.In conclusion,C.carpio var.Quanzhouensis cultured in paddy fields had a higher umami taste,but also a heavier earth odor;C.carpio var.Quanzhouensis cultured in ponds had a weak soil flavor,but umami taste was not strong.
