Amino Acid Composition of Pearl Oyster Pinctada fucata martensii at the Different Size Groups in Liusha Bay
摘要
Abstract
This study compared and analyzed the biochemical composition and amino acids composition of pearl oyster (Pinctada fucata martensii) at the different size groups including large groups, middle groups and small groups with (26.22 ± 4.24)g, (13.91 ± 2.57)g and (6.05 ± 1.28)g, respectively. The results showed that mass fraction of crude protein of P. f. martensii at the different size groups were 59.96%, 65.48% and 66.80%, respectively; the mass fraction of crude lipid were 4.06%, 4.51% and 5.83%, respectively; the mass fraction of ash were 22.24%, 18.34% and 16.90%, respectively; and the mass fraction of nitrogen free extract were 13.75%, 11.66% and 10.48%, respectively. And the mass fraction of essential amino acids (EAA) at large groups, middle groups and small groups were 17.55%, 18.76% and 19.44%, respectively; the ratios of EAA and total amino acids (TAA) were 36.57%, 36.57%and 36.89%, respectively; the mass fraction of delicious amino acids (DAA) were 22.50%, 24.01% and 24.31%, respectively; the ratios of DAA and TAA were 46.89%, 46.79% and 46.26%, respectively. With the growth and development of P. f. martensii, the mass fraction of crude protein and crude lipid increased gradually, but the mass fraction of ash and nitrogen-free extract decreased gradually. Except Glycine, the average mass fraction of amino acids, the EAA and DAA increased significantly with the growth and development of individuals in a certain stage. It cloud provide basic data and theoretical data for the development of pearl oyster artificial diets.关键词
