A combined system of liquid-liquid extraction and membrane separation was developed to concentrate and separate polyunsaturated fatty acids (PUFAs) as acylglycerols from the hydrolysate of fish oil, after being selectively hydrolysed with lipase. With consideration to potential industrial applications to membrane separations, conventional cross-flow filtrations and rotating disk membrane systems were examined.<BR>In the cross-flow filtration system, permeate flux decreased rapidly during one-run batch treatment. Showing comparatively poor performance. The use of a gear pump in the system damaged oil quality. In the rotating disk membrane system, permeate flux did not decrease and separation performance was good. The O/W emulsion in the cross-flow filtration system differed from that in the rotating disk membrane system. Average oil droplet size in the rotating disk menbrane system was larger, than that in the cross-flow filtration system. This possibly being a factor affecting membrane separation.<BR>The rotating disk membrane system was concluded applicable on a large scale process to the separation of physiological substances such as PUFAs which are easily damaged.
