Lipids of Cod Muscle and the Effect of Frozen Storage
The lipid composition of fresh and frozen cod (Gadus morhua) muscle was studied using silicic acid chromatography. Dark cod muscle contained about three times as much total lipid as white muscle but the composition was quite similar. The most significant difference was that the dark tissue lipid con...
