Evaluation of muscle nutrition components of ecological grass carp(Ctenopharyngodon idella)cultured in ponds with micro-flow environment
摘要
Abstract
In order to understand the muscle quality and drug residues of grass carp(Ctenopharyngodon idella)in the pond with micro-flowing water,a comparative analysis was conducted on the conventional nutrients,amino acids,fatty acids and drug residues in the muscle of grass carp cultured in micro-flowing water ponds and in tradi-tional intensive ponds.The water quality of culturing water sources was simultaneously monitored.The results showed that the water source for grass carp pond farming was free of unusual color,odor and taste,meeting the re-quirements of the Environmental Conditions of Freshwater Aquaculture Areas for Pollution-Free Agricultural Prod-ucts(NY/T 5361-2016)standard.The crude protein content in the muscle of grass carp cultured in micro-flowing ponds was(20.21±0.33)%,which was significantly higher than that in traditional intensive ponds(P<0.05).The total amino acids(TAA),total essential amino acids(TEAA),and total flavor amino acids(TDAA)in the muscle of grass carp cultured in micro-flowing ponds were(17.56±0.60)%,(7.22±0.33)%,and(8.02±0.24)%,respectively,which were all significantly higher than those in traditional intensive ponds(P<0.05).The proportion of polyunsaturated fatty acids(PUFA)in the total fatty acids of grass carp in the micro-flowing ponds was(32.44±1.33)%,which was significantly lower than that in traditional intensive ponds(P<0.05).The contents of saturated fatty acids(SFA)and monounsaturated fatty acids(MUFA)were(23.35±0.10)%and(44.21±1.24)%,respectively,which showed no significant difference from those in traditional in-tensive ponds(P>0.05).No drug residues were detected in the grass carp from either environment.The study in-dicates that C.idella cultured in micro-flowing pond environments have balanced muscle amino acid composition,reasonable nutritional value and are safe for consumption.关键词
