Abstract

This study was conducted to characterize the nutrion of commercial Kwamegi, a Korean traditional food made from semi-dried Pacific saury, Cololabis saira. The ratios of saturated and monoenoic fatty acids to polyenoic fatty acids in commercial Kwamegi ranged from 0.52-0.75 and 1.01-1.53, respectively. The major fatty acids in commercial Kwamegi were 16:0 (9.1-14.2%), 20:1n-9 (8.6-16.1%), 22:1n-9 (15.7-22.1%), and 22:6n-3 (11.0-18.0%). The total amino acid content of commercial Kwamegi ranged from 27.10-33.19 g/100 g. The major amino acids in commercial Kwamegi were aspartic acid (11.8-13.0%), glutamic acid (14.3-16.0%), leucine (7.8-8.5%), and lysine (7.5-9.0%), which accounted for more than 41% of the total amino acid content. The mineral content of commercial Kwamegi ranged from 0.7-4.3 mg/100 g for zinc, 279.6-466.3 mg/100 g for potassium, 41.7-128.3 mg/100 g for calcium, 38.8-77.8 mg/100 g for magnesium, and 224.3-348.4 mg/100 g for phosphorus. These results suggest that commercial Kwamegi is a superior food in terms of nutrition and health.
