초록
To investigate of the content of fatty acids and cholesterol level in Raja Skates, the skate was purchesed from Yangdong Fisheries market in Kwangju, Korea. The experimental skate contained moisture 77.1%, crude protein 20.5%, crude lipid 0.68% and ash 1.72% as the general components. The fatty acids composition of skate are 28 kinds, such as 10 kinds of saturated fatty acid and 18 kinds of unsaturated fatty acid. There are 5 kinds of odd numbered fatty acid, such as C15:0, C17:0, C19:0, C25:0. Lignoceric acid shows 11% content. As an unsaturated fatty acid, getoleic acid, C22:1: selecholeic acid, C24:1:9, 12-hexadecadienic acid, C16:2: trans-linolelaidic acid, C18:2:13, 16-docosadienoic acid, C22:2: are analyzed as the particular one. The p/s ratio of skates is 1.02 and n-3/n-6 ratio of Skates is 0.82, respectively. The content of cholesterol level of Skates muscle is less than 20mg%, and liver contains 300-500 mg% and Nechang-tang contains 100mg% each.
