Abstract
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.
