应用生化分析方法对雌雄牛蛙肌肉和蛙皮的营养成分、氨基酸含量进行了定量分析比较。蛙皮中粗蛋白、Ca、Zn含量明显高于肌肉 ,分别为肌肉的 1 2 1倍、3 16倍、1 39倍 ,但蛙皮中氨基酸总量却与肌肉相当 ;雌雄牛蛙个体间各营养成分及氨基酸含量均无明显差异 ;性成熟阶段的雄蛙出肉率要明显高于雌蛙
The biochemical analysis methods were used to quantitatively analyze the nutritional content and amino acid content of muscle and frog skin of male and female bullfrogs. The content of crude protein, Ca and Zn in frog skin was significantly higher than that of muscle, which was 112 times, 316 times and 139 times higher than that of muscle, but the total amount of amino acids in frog skin was the same as that of muscle; Composition and amino acid content were no significant difference; sexual maturity of the male frog meat was significantly higher than the female frog
