A process for obtaining fish meal which is essentially free of oil, as well as recovering valuable free polyunsaturated fatty acids, comprising hydrolyzing membrane phospholipids in comminuted fish with aqueous alkali solution, at a temperature which is not substantially above ambient, adding a strong acid to release free polyunsaturated fatty acids, recovering the free fatty acids from the aqueous phase by mechanical separation, and drying the aqueous phase. |
