Analysis of muscle nutrient composition of Cyprinus carpio var. color in Qingtian and Jinhua

Abstract:

Nutritional composition, mineral elements, amino acids and fatty acids in muscle were investigated in Cyprinus carpio var. color from Qingtian and Jinhua. Results showed that contents of crude fat(fresh weight) in Qingtian Cyprinus carpio var color(QC) were significantly higher than that in Jinhua Cyprinus carpio var. color (JC) (P<0.01); 17 amino acids were obtained in both populations. The percentage of all amino acids in JC were higher than those in QC but Glycine and Cystine(P<0.05); Based on the criteria of amino acid score (AAS), the top two limiting amino acids in QC were Valine and Methionine+Cysteine, and the top two limiting amino acids in JC were Methionine+Cysteine and Valine; 16 fatty acids were detected in all muscle samples. C16:1, C18:1n9c, C18:3n3 and monounsaturated fatty acid in QC were higher than those in JC (P<0.05); C18:0 and C20:4n6 in JC were higher than those in QC(P<0.05). The contents of Zn and Cu in QC were significantly higher than those in JC(P<0.05), and the contents of Ca, P and Mg in JC were significantly higher than those in QC(P<0.05).
