Analysis on Nutritional Components in New Variety‘Dongyou No.1'and Its Parental Populations of Small Abalone Haliotis diversicolor

The nutritional components from foot muscle of RITAI Haliotisdiversicolor(Japan population and Taiwan population)and their reciprocal hybrids(‘Dongyou 1')were comparatively analyzed according to the national standard method.The protein content in‘Dongyou 1'was significantly lower than that of Japan population but higher than that of Taiwan population,while the lipid content in‘Dongyou 1'was higher than its parents.Total amino acids(TAA),essential amino acids(EAA)and delicious amino acids(DAA)in ‘Dongyou 1'and Japan population are higher than Taiwan population(P<0.05).SRCAA of all the 3groups are higher than 80%,and E/T and E/N of them are consistent with the FAO/WHO proteinaceous model.Contents of saturated fatty acid(SFA)and essential fatty acid(EFA)in ‘Dongyou 1'were lower than its parents;Content of unsaturated fatty acid(UFA)in ‘Dongyou 1'was between that of Taiwan population and Japan population.ΣPUFA(n-6)/ΣPUFA(n-3)of ‘Dongyou 1'was lower than its parents,andΣPUFA/ΣSFA of ‘Dongyou 1'was higher than its parents.All the 3kinds of foot muscles contained complete and equilibratory amino acids and fatty acids,and have been proved to be nutritive protein sources,furthermore,Dongyou No.1 may be preferable than its parents for healthy diet.
