摘　　要：为探究4个不同家系斑点叉尾的鱼肉品质,及为斑点叉尾鮰品种选育提供科学依据,通过理化分析等方法测定不同家系斑点叉尾鮰鱼肉的质构特性、风味物质等指标,比较品质差异。结果显示:不同家系斑点叉尾鱼肉中水分和必需氨基酸含量无显著性差异(P>0.05);DZ29-1家系鱼肉肌肉硬度、回复性、弹性和内聚性显著高于其他家系(P<0.05);鱼肉中的游离氨基酸、腺苷三磷酸、腺苷二磷酸、腺苷一磷酸与肌苷酸在不同家系间存在差异,其中DZ29-1家系鱼肉中腺苷三磷酸、腺苷一磷酸和肌苷酸含量最高;4个家系鱼肉中的挥发性气味物质种类相似。试验结果表明,不同家系斑点叉尾鮰鱼肉的质构特性和滋味及风味物质存在差异,试验结果可为筛选斑点叉尾优质品种提供参考,促进我国斑点叉尾产业高质量发展。To provide scientific support for breeding programs aimed at enhancing the taste and palatability in muscle of channel catfish Ictalurus punctatus,the texture properties and flavor components in muscle were assessed and muscular quality differences in compositions were compared in four G2 lineages of 30 month old channel catfish designed as KB29-1,K23-1,DZ29-1,and 20-1.There were significantly higher muscular hardness,recovery rate,elasticity and chewiness in DZ29-1 lineage than those in other lineages(P<0.05),without significant differences in moisture mass fraction and proportion of essential amino acids in the muscle of the different lineages(P>0.05).The significantly different contents of free amino acid,adenosine triphosphate(ATP),adenosine diphosphate(ADP),adenosine monophosphate(AMP)and inosinic acid(IMP)were observed in the muscle of the four lineages(P<0.05),with the maximal values in DZ29-1 lineage.The types of volatile substances were found to be similar in the muscle of the four lineages.There are significant differences in the textural characteristics and flavor components among the four lineages,which provides guide to screening high-quality varieties and promotes the development of channel catfish culture industry in China.
