Quality Evaluation and Nutritional Composition Analysis of Muscle in Procypris merus
[Objective]The nutritional composition of muscle in Procypris merus was analyzed to provide a reference for healthy breeding and protection and utilization of germplasm resources of P.merus.[Method]P.merus were selected from Wuming District(WM),Lingshan County(LS)and Xingbin District(XB)of Guangxi to determine the nutritional composition of muscle and analyze the nutritional value.[Result]The crude protein and crude fat content in muscle of the 3 groups of P.merus were 18.68%-19.44% and 0.83%-1.21%,respectively,and the water and crude fat contents in LS group were significantly higher than WM and XB groups.16 kinds of amino acids were obtained in 3 groups of P.merus,among which the content of glutamic acid(Glu)was the highest,while the content of methionine(Met)was the lowest.The content of total amino acid(TAA),total essential amino acid(EAA),total non-essential amino acid(NEAA)and total delicious amino acid(DAA)of XB group were significantly higher than WM and LS groups.The first and second limiting amino acids of the 3 groups were Met+cystine(Cys)and valine(Val),respectively.Except Met and Val,the amino acid score(AAS)of other amino acids in 3 groups were all higher than 1,and the chemical score(CS)were all higher than 0.75,and the essential amino acid index(EAAI)were 78.54-86.32.A total of 29 kinds of fatty acids were detected in 3 groups of P.merus.The contents of C13:0,C15:0,C17:0,C19:1 and C21:5 of XB group were significantly higher than WM and LS groups.The contents of DHA and n-3 PUFA in XB group were significantly higher than LS group.[Conclusion]The nutrient composition of P.merus of Xingbin District,Wuming District and Lingshan County of Guangxi are balanced.The amino acid and unsaturated fatty acid content are abundant.The content and composition of amino acid and fatty acid in Xingbin District are higher than Wuming District and Lingshan County.
