  • Process for enrichment of fat with regard to polyunsaturated fatty acids and phospholipids, and application of such enriched fat
    Patent number: 5336792
    Abstract: To enrich fat with polyunsaturated fatty acids and phospholipids a presscake is formed of iced fjord herring containing polyunsaturated fatty acids and phospholipids. The presscake is dissolved in a fat dissolving polar alcohol; the solids are separated; and the liquid evaporated until a precipitation of a first fat fraction occurs. The first fat fraction is separated; and evaporation resumed until the precipitation of a second fat fraction. The second fat fraction, with a higher content of polyunsaturated fatty acids and phospholipids than the first fat fraction, is separated from the remainder of the solution.
