Comparative Analysis on Main Nutrient Compositions in Zhouhe Carp and Ukraine Scaled Carp

In this study,the contents of the crude protein,water,ash,crude fat,amino acid and fatty acid of the Zhouhe carp and Ukraine scaled carp were analyzed.The results show that the contents of crude protein(19.20%),water(78.76%)and ash(1.45%)in Ukraine scaled carp were significantly higher than Zhouhe carp’s(18.52%,76.83%,1.20%;P0.01).But the content of crude fa(t3.76%)in Zhouhe carp was significantly higher than Ukraine scaled carp’s(1.79%;P0.01),and the types of fatty acids,the total fatty acid amount and the contents of essential fatty acid in Zhouhe carp(11,2.88%,0.60%)were higher than Ukraine scaled carp’s(10,0.64%,0.10%).The nutrient values of fatty acid in Zhouhe carp are higher than Ukraine scaled carp’s.There were 18 types of amino acids in Zhouhe carp and Ukraine scaled carp.The contents of essential amino acids,flavour amino acids and total amino acids in Ukraine scaled carp(8.30%,7.58%,20.29%)were higher than Zhouhe carp’s,respectively(7.53%,6.48%,17.82%).The amino acid compositions of the protein in Ukraine scaled carp are better than that in Zhouhe carp.In conclusion,the Ukraine scaled carp has more nutriology advantages than Zhouhe carp.
