영문 초록

This study was carried out to investigate the seasonal changes of body composition of Scartelaos gigas collected from Gangjin, Jeollanam-do. Proximate composition by seasons of S. gigas muscle were moisture contents 67.6~79.9%, crude protein 15.4~18.8%, crude lipid 0.7~2.8%, and crude ash 0.8~3.1%. Proximate composition in liver of S. gigas was moisture contents 10.3~24.3%, crude protein 14.0~16.6%, crude lipid 53.4~59.2%, and crude ash 0.2~0.5%. Calcium content in the muscle of S. gigas was 341~631 mg/100 g, iron 2.8~8.3 mg/100 g, potassium 135~240 mg/100 g, magnesium 28.5~49.3 mg/100 g, manganese 0.3~1.6 mg/100 g, copper 0.2~0.4 mg/100 g, sodium 107~148 mg/100 g, zinc 1.5~2.6 mg/100 g. Calcium in the liver was 13.3~377.1 mg/100 g, iron 5.3~39.1 mg, potassium 120.2~195.9 mg, magnesium 15.3~60.9 mg, manganese 0.2~0.6 mg, copper 0.2~0.6 mg, sodium 73.7~157.3 mg, zinc 1.3~3.8 mg. The major amino acid in the muscle of S. gigas was glutamic acid, isoleucine and leucine in order. The major amino acid in the liver of S. gigas was glutamic acid, lysine, valine in order. In case of the fatty acids, the major saturates of the muscle was palmitic acid 20~48%, stearic acid 6~19%, monoenes was palmitoleic acid (C16 : 1), oleic acid (C18 : 1) and polyenes was EPA, DHA. The major fatty acid of the liver were the same as the muscle. Nutrient content of S. gigas varies depending on the spawning and hibernation period, so it is desirable to use it appropriately.
