Abstract
Production of ω-3 fatty acid concentrates from seal blubber oil (SBO) and menhaden oil (MHO) upon enzymatic hydrolysis by Candida cylindracea lipase was optimized. In this process, the content of total ω-3 fatty acids, Y 1; eicosapentaenoic acid, Y 2; and docosahexaenoic acid, Y 3, in the final product was maximized. A three-factor central composite rotatable design was used to study the effect of enzyme concentration (X 1), reaction time (X 2), and reaction temperature (X 3). Second-order polynomial regression models for Y 1, Y 2, and Y 3 were employed to generate response surfaces. After hydrolysis, a maximum of 54.3% total ω-3 fatty acids was obtained from SBO at an enzyme concentration of 308 U/g oil, a reaction time of 40 h, and a reaction temperature of 37°C. Similarly, a maximum of 54.5% total ω-3 fatty acids was obtained from MHO at an enzyme concentration of 340 U/g oil, a reaction time of 45 h, and a reaction temperature of 38°C.
