Omega-3 is a polyunsaturated fatty acid (PUFA), which is an essential nutrient for health. Through this, the x3-PUFA concentration has increasingly gained interest. In this study, the concentration of x3-PUFA of Lantern fish oil was investigated through utilisation of membrane separation. Between tested membranes, it was observed that ETNA01PP separates x3-PUFA more selectively. Additionally, effects of main parameters affecting the x3-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 x3-PUFA concentration. To determine the optimal process parameters, the Derringer's desirability prediction tool was employed in which the highest x3-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.

“…The Box-Behnken design (BBD), only have three levels, is a popular form of RSM and has been successfully applied by a number of investigators for optimizing complex processes, including polysaccharides extraction [23][24][25][26]. It is more efficient and easier to arrange and interpret experiments in comparison with others [27].…”

“…Because ultrasonic extraction could obtain higher efficiency of extraction and more healthy extractive by reducing the handling time and use of solvent; meanwhile, its low operated temperatures can reduce the heat loss caused by high temperatures; in addition, it also prevents the vaporization of solvent during boiling and preserves bioactive substance. It is very useful for the extraction of thermolabile compounds [18,19]. In the present study, the best extraction technological parameters for polysaccharides from C. songaricum using ultrasonic-assisted extraction procedure is being reported for the first time.…”

“…We found that the ultrasonic power and extraction temperature were significant for the polysaccharide extraction from C. songaricum at the 99 % confidence level. While Ajaz Ahmad [19] found that the extraction temperature was an important factor for extraction efficiency of the polysaccharide at the 95 % confidence level in optimal conditions of ultrasonic-assisted extraction of polysaccharides from Paeonia emodi. The p-value was used as evaluation index to check the significance of each coefficient and the interaction strength between variables [20].…”
