摘　　要：[目的]对金线棘胸蛙、粗皮棘胸蛙和细皮棘胸蛙进行营养成分的测定分析。[方法]分别采集3种棘胸蛙肌肉样本300 g,各项营养成分按照GB 5009—2016进行测量。[结果]金线棘胸蛙较粗皮棘胸蛙和细皮棘胸蛙的蛋白质含量高,脂肪含量低;金线棘胸蛙、粗皮棘胸蛙和细皮棘胸蛙均富含17种氨基酸,总量占比分别为16.580%、7.528%和7.632%,其中7种必需氨基酸总量分别占6.060%、3.070%和3.100%,金线棘胸蛙蛙鲜味氨基酸含量最高,脂肪酸种类最少;粗皮棘胸蛙不饱和脂肪酸最高;金线棘胸蛙Ca、P含量显著高于粗皮棘胸蛙和细皮棘胸蛙;金线棘胸蛙微量元素均低于粗皮棘胸蛙和细皮棘胸蛙;粗皮棘胸蛙Zn、Fe、Mn、Mg和Sr的含量最高。[结论]金线棘胸蛙鲜味优于其他2种,粗皮棘胸蛙和细皮棘胸蛙营养及药用价值优于金线棘胸蛙,他们的综合价值优于金线棘胸蛙。[Objective]The nutritional components of Rana spinosa with golden thread,Rana spinosa with rough-skinned and Rana spinosa with thin-skinned were determined and analyzed.[Method]300 g of muscle samples were collected from three species of Rana spinosa,and the nutritional components were measured according to GB 5009-2016.[Result]The protein content was higher and the fat content was lower in Rana spinosa with golden thread than that in Rana spinosa with rough-skinned and Rana spinosa with thin-skinned.17 kinds of amino acids were rich in Rana spinosa with golden thread,Rana spinosa with rough-skinned and Rana spinosa with thin-skinned,which account for 16.580%,7.528%and 7.632%respectively,the total contents of 7 kinds of essential amino acids were 6.060%,3.070%and 3.100%,respectively.The contents of umami amino acids of Rana spinosa with golden thread were the highest and the types of fatty acids were the least.The unsaturated fatty acid of Rana spinosa with rough-skinned was the highest.The Ca and P contents of Rana spinosa with golden thread were significantly higher than those of Rana spinosa with rough-skinned and Rana spinosa with thin-skinned.The trace elements of Rana spinosa with golden thread were lower than those of Rana spinosa with rough-skinned and Rana spinosa with thin-skinned.The contents of Zn,Fe,Mn,Mg and Sr were the highest in Rana spinosa with rough-skinned.[Conclusion]The umami taste of Rana spinosa with golden thread is superior to the other two species,the nutritional and medicinal values of Rana spinosa with rough-skinned and Rana spinosa with thin-skinned are superior to Rana spinosa with golden thread,and their comprehensive values are superior to it.
