Popis: Methods of processing hake livers whereby the protein fraction and the water-soluble nutritional factors may be recovered in addition to the oil and oil-soluble vitamins, have been examined. Methods involving (a) partial tissue digestion by papain, and (b) water-extraction (under conditions involving some autolysis) have been compared. The water-soluble fraction from process (b) has been subjected to evaporation under reduced pressure and to spray-drying. The powder thus obtained has been analysed for nitrogenous components, glycogen, vitamins of the B group (including vitamin B12) and for fifteen inorganic elements.
