A preferred temperature is 70 DEG C. The proteinaceous residue is suitable for animal feeding.ALSO:A process for extracting fatty substances and lipids from proteinaceous material consisting of fish or other aquatic animals to obtain a protein product suitable for use as a nutritive, in which extraction fats and other objectionable taste- and odour-producing substances such as phospholipides are removed from the proteinaceous material, comprises extracting the proteinaceous material moistened with water, with a polar solvent comprising one or more of n-butanol, sec.-butanol, and iso-butanol, the extraction being carried out at a temperature below the azeotropic boiling point of the solvent with water.
