Marine oils are deodorized by contact with an effective amount of crystalline siliceous molecular sieves having strongly organophilic properties and pore diameters of at least 5.5 Angstroms. The molecular sieves selectively adsorb odorous organic amines and other odor-producing molecular species, such as aldehydes and ketones, without alteration of the essential unsaturated fatty acid triglycerides.
