Abstract

Oils are separated from fish livers, such as halibut livers, by treating the minced livers with dilute alkali, separating the resulting scum and treating it with hot water, adjusting the hydrogen ion concentration to faint alkalinity, causing the emulsion to break with addition, if necessary, of an electrolyte, and separating the oil. Minced halibut livers are treated with 5 per cent caustic soda solution at 40 DEG C., for several days. The oily scum is separated and after treating with boiling water, the mixture is adjusted to pH8 by adding hydrochloric acid. Breaking of the emulsion may be assisted by addition of anhydrous sodium sulphate. The oil is then separated by centrifuge.
