Abstract
Oils are extracted from fish livers by treating with glacial acetic acid. Livers of the dog-fish, after removal of the gall bladder and veins, are minced and warmed to 70 DEG C. with sufficient glacial acetic to bring the mixture to a pH value of 4 6 or less. After a short macerating and settling period the oil is drawn off and the residue is mixed with water to yield a further quantity of oil, or the oil may be extracted by solvents. The aqueous layer containing proteins may be worked up to yield extracts and the solid residue used in the preparation of food stuffs. An anhydrous neutral salt such as sodium sulphate may be added to the glacial acetic acid to aid the coagulation and denaturing of the proteins in which case heating of the mixture is unnecessary. The livers may also be treated whole when a macerating period of several days is necessary. According to the third Provisional Specification, oil is extracted from fish livers by treating with p anhydrous sodium sulphate alone.ALSO:Fish livers are minced and heated with glacial acetic acid to extract the oil therefrom, water is then added to the residue to release a further amount of oil, and the solid oil-free residue and the aqueous extract containing protein products are used in the manufacture of food preparations. An anhydrous neutral salt such as sodium sulphate may be added to the glacial acetic acid to aid the coagulation and denaturing of the proteins, in which case heating is unnecessary.
