Analysis of muscle nutritional components of three cultured populations of Cipangopaludina cathayensis
摘要
Abstract
The purpose of this study was to study and analyze the composition and content of routine nutrients,amino acids,fatty acids,and mineral elements in muscle of three cultured populations of Cipangopaludina cathayensis,so as to provide a reference for the development and utilization of Cipangopaludina cathayensis germplasm resources.A total of 180 Cipangopaludina cathayensis with an average weight of(32.12±0.17)g were randomly divided into three groups with 60 Cipangopaludina cathayensis in each group.After shelling,the muscles were taken to test their nutritional components.The results showed that the crude protein,total amino acids,essential amino acids,and delicious amino acids in muscle of Luchuan County population were significantly higher than those of other populations(P＜0.05).The amino acid score,chemical score,and essential amino acid index of Liujiang population were the highest.The contentrations of unsaturated fatty acids and polyunsaturated fatty acids in muscle of Luchuan County population were significantly higher than those of other populations,and the atherosclerosis index(IA)and thrombosis index(IT)were lower than those of other populations(P＜0.05).The ratio of sigma-n-3/sigma-n-6PUFA of the three populations was in line with the recommended value of FAO/WHO for human diet(0.1～0.2).The contentrations of P and Ca in muscle of Rongshui County population were significantly higher than those of other populations(P＜0.05).The study indicates that the muscle protein content of the three cultured populations is higher,the fat content is lower,and the delicious amino acids and unsaturated fatty acids are higher.The nutritional value of the muscle of Luchuan County population are better than those of other populations.关键词
