Karahadian, R. Lindsay] Menhaden, cod liver and siscowet lake trout oils were vacuum steam deodorized at 100°C to 210°C using volatile acid (acetic and hydrochloric) and base (ammonium hydroxide) solutions (0.005N-0.25N) as steam sources. Volatiles in oils were analyzed by Tenax GC headspace analysis, and flavor and odor quality was evaluated. Deodorization of oils at 100°C with acidic solutions yielded oils that lacked the burnt/fishy flavors compared to similar oils that were deodorized with either water or alkaline solutions. Acid catalyzed hydrations of fishy aldehydes by deodorizing acids and flavor masking byt,c-2,6-nonadienal appeared to cause the suppression of fishy flavors in fish oils deodorized by acid solutions. Oils deodorized at 210°C exhibited less intense fishy flavors, and lower concentrations of fishy aldehydes,t,t,c-2,4,7-decatrienal,t,c,c,-2,4,7-decatrienal, andc-4-heptenal.
