Summary Omega‐3 is a polyunsaturated fatty acid ( PUFA ), which is an essential nutrient for health. Through this, the ω3‐ PUFA concentration has increasingly gained interest. In this study, the concentration of ω3‐ PUFA of Lantern fish oil was investigated through utilisation of membrane separation. Between tested membranes, it was observed that ETNA 01 PP separates ω3‐ PUFA more selectively. Additionally, effects of main parameters affecting the ω3‐ PUFA concentration, including temperature (20–40 °C), pressure (3–5 bar) and stirring rate (0–200 rpm), were evaluated through Box–Behnken design of experiment. According to anova , all these parameters showed significant impact on ω3‐ PUFA concentration. To determine the optimal process parameters, the Derringer's desirability prediction tool was employed in which the highest ω3‐ PUFA concentration of 35.1058 wt. % was estimated. The obtained optimal condition was found to be the temperature of 36.19 °C, pressure of 4.82 bar and stirring rate of 43.01 rpm with a desirability value of 0.99.
