养殖与饲料2024年第3期三角鲤肌肉营养成分及品质评价赵何勇，温守欧，韦玲静，甘宝江，卢玉典，莫飞龙*广西壮族自治区水产引育种中心，南宁530031摘要［目的］探讨不同养殖环境下三角鲤的肌肉营养品质，为三角鲤的健康高效养殖及新品种选育提供参考。［方法］测定分析3个三角鲤养殖群体（广西南宁市武鸣区（WM）、广西钦州市灵山县（LS1）、广西钦州市灵山县（LS2））的肌肉一般营养成分、氨基酸、脂肪酸，并进行营养价值评估。［结果］依据氨基酸评分（AAS）标准和化学评分（CS）标准，3组鱼肉的第一限制性氨基酸均为Met+Cys；LS2组各必需氨基酸的AAS评分、CS评分和氨基酸指数EAAI均为最高，其次为LS1组，WM组最低。3组鱼肉均检测出25种脂肪酸，LS1组的ΣPUFA含量（23.34%）显著高于LS2组（19.92%），WM组的EPA+DHA含量（4.26%）显著高于LS2组。［结论］3个养殖场三角鲤肌肉营养丰富，可作为人体补充蛋白质的优质来源。LS2组肌肉氨基酸营养价值优于其他2组，LS1组肌肉必需脂肪酸营养价值优于LS2组。关键词三角鲤；营养；氨基酸；脂肪酸；肌肉品质NutrientcompositionandqualityevaluationofNutrientcompositionandqualityevaluationofCyprinusmultitaeniataCyprinusmultitaeniataZHAOHeyong,WENShouou,WEILingjing,GANBaojiang,LUYudian,MOFeilong*AquaticBreedingCenterofGuangxiZhuangAutonomousRegion,Nanning530031,ChinaAbstractAbstract[Objectives]ThemeatnutritionalqualitiesofCyprinusmultitaeniataunderdifferentbreedingenvironmentswerestudiedtoprovidereferenceforthehealthyandefficientfarmingandbreedingofCyprinusmultitaeniata.[Methods]Thegeneralnutrientcomposition,aminoacids,andfattyacidsofthemeatsfromthreepopulationsofCyprinusmultitaeniatafarmedinWumingDistrict(WM)ofNanningCity,LingshanCounty1(LS1)andLingshanCounty2(LS2)ofQinzhouCity,GuangxiProvince,weremeasuredandanalyzed.Thenutritionalvaluewasevaluated.[Results]Accordingtotheaminoacidscore(AAS)andchemicalscore(CS)criteria,thefirstlimitingaminoacidoffishmeatinallthreepopulationswasMet+Cys.TheAASscore,CSscore,andindexofaminoacid(EAAI)ofeachessentialaminoacidintheLS2populationwasthehighest,followedbytheLS1population,andtheWMpopulationwasthelowest.25fattyacidsweredetectedinfishmeatfromall3popula‐tion.Thecontentof...
