Equilibrium of fish oil-solvent-water system had been examined at a room temperature under normal pressure as a fundamental study for the preparation of fatless fish meal by simultaneous removal of crude fat and moisture from boiled scraps of fish. When acetone is used as a solvent, the proportion of the solvent in this system is very large as shown in Fig. 1. In other words large quantity of acetone is necessary for practical extraction. Therefore, it is desirable to remove fat and moisture from the scraps with smaller quantity of an ex-tractant on practical use. Although the best extractant on pratical use should not be selected only by the condition of this equilibrium, it has been ascertained that the mixture of die-thylamine and ethyl ether (or benzene) is suitable on account of quantitative economy of an extractant.
