A sample of barracudina, a small fish potentially available in large quantities off Nova Scotia, contained 17.7% body lipid of which 10% was triglyceride and 85% wax ester. The triglyceride, of calculated iodine value 48, was unusually rich in 14:0 (25.8%), 18:0 (4.3%), 20:0 (1.19%), 22:0 (0.45%) and 24:0 (0.75%). The wax ester fatty acids had a calculated iodine value of 126 and a “normal” marine oil fatty acid composition. The wax ester fatty alcohols contained 42.2% hexadecanol, 29.5% octadecenols, 8.2% eicosenols and 3.8% docosenols. Certain interrelationships between fatty alcohols and fatty acids are indicated by details of composition. The potential exploitation of barracudina lipid as a substitute for sperm oil in some uses appears possible. |
