摘要：

Omega-3 is a polyunsaturated fatty acid (PUFA), which is an essential nutrient for health. Through this, the 3-PUFA concentration has increasingly gained interest. In this study, the concentration of 3-PUFA of Lantern fish oil was investigated through utilisation of membrane separation. Between tested membranes, it was observed that ETNA01PP separates 3-PUFA more selectively. Additionally, effects of main parameters affecting the 3-PUFA concentration, including temperature (20-40 degrees C), pressure (3-5bar) and stirring rate (0-200rpm), were evaluated through Box-Behnken design of experiment. According to anova, all these parameters showed significant impact on 3-PUFA concentration. To determine the optimal process parameters, the Derringer's desirability prediction tool was employed in which the highest 3-PUFA concentration of 35.1058 wt. % was estimated. The obtained optimal condition was found to be the temperature of 36.19 degrees C, pressure of 4.82bar and stirring rate of 43.01rpm with a desirability value of 0.99.
