초록

This study was conducted to identify the food components and nutrition value of major fish roes on the market in Korea. The proximate compositions of the roes were 60.02-82.85% moisture, 14.61-29.21% protein, 1.24-14.59% lipid and 0.88-1.78% ash. The major total amino acids in the roes were glutamic acid, leucine, aspartic acid, lysine, and alanine. The major fatty acids were 22:6n-3 (docosahexenoic acid, 9.37-32.68%), 16:0 (5.96-21.39%), 18:1n-9 (12.64-25.30%), and 20:5n-3 (eicosapentaenoic acid, 3.79-16.99%). The mean major-mineral levels were phosphorus (291.63 mg/100 g edible portion), potassium (271.00 mg), sodium (175.86 mg), calcium (24.02 mg), and magnesium (22.15 mg). The mean trace-mineral levels were zinc (7.75 mg), iron (3.68 mg), and copper (0.81 mg). The results suggest that these fish roes are good sources of proteins, amino acids, n-3 fatty acids and minerals.
