초록

In this study, we analyzed the nutritional compositions of five species of flounder inhabiting Korean coastal waters. In terms of proximate composition, the moisture and crude fat contents of flounders ranged from 75.16±0.37 to 79.94±0.09 g/100 g and 0.48±0.02 to 4.07±0.09 g/100 g, respectively, and showed a negative correlation. Crude protein contents among the five species were found to range from 18.74±0.37 to 19.69±0.44 g/100 g and showed no significant inter-species differences. Among these flounders, Clidoderma asperrimum was characterized by the highest crude fat and total fatty acid contents of 4.07±0.09 g/100 g and 2,739.39 mg/100 g, respectively, as well as the highest content of polyunsaturated fatty acids, including EPA and DHA, at 620.24 mg/100 g. Hippoglossoides dubius was found to have a total amino acid content of 18,971.36 mg/100 g. Our finding in this study regarding the nutritional profiles of flounders will provide valuable information for industrial use.

Abstract

In this study, we analyzed the nutritional compositions of five species of flounder inhabiting Korean coastal waters. In terms of proximate composition, the moisture and crude fat contents of flounders ranged from 75.16±0.37 to 79.94±0.09 g/100 g and 0.48±0.02 to 4.07±0.09 g/100 g, respectively, and showed a negative correlation. Crude protein contents among the five species were found to range from 18.74±0.37 to 19.69±0.44 g/100 g and showed no significant inter-species differences. Among these flounders, Clidoderma asperrimum was characterized by the highest crude fat and total fatty acid contents of 4.07±0.09 g/100 g and 2,739.39 mg/100 g, respectively, as well as the highest content of polyunsaturated fatty acids, including EPA and DHA, at 620.24 mg/100 g. Hippoglossoides dubius was found to have a total amino acid content of 18,971.36 mg/100 g.
