| Abstract: | The amino acid content and fatty acid composition in the flesh of clam Meretrix lyrata were determined.A total of 17 amino acids were detected,accounting for 52.26% of total dry tissue weight;the content of four kinds of flavor amino acids(aspartic acid,glutamic acid,glycine and alanine) was 22.07%,accounting for 42.23% of total amino acids;the content of essential amino acids(EAA) was 20.72%,and the composition ratio of essential amino acids was in line with the standard recommended by FAO/WHO,indicating that M.lyrata has high protein content and is a high-quality protein source.A total of 20 kinds of fatty acids were detected in the tissue of M.lyrata,in which the percentage of polyunsaturated fatty acids was 34.20%,and the percentages of EPA and DHA were 15.07% and 11.78%,respectively,indicating that the composition of fatty acids of M.lyrata is relatively complete and the clam has higher nutritional value. |
