摘要
Atlantic and Gulf of Mexico menhaden (Brevoortia spp) oils from refining, bleaching and deodorizing steps were analyzed for volatile components by combined techniques of dynamic headspace sampling, high resolution gas chromatography and mass spectrometry. Results indicated that alkali‐refining and clay‐bleaching removed many odorous short‐chain oxygenated compounds and alkylbenzenes; steam‐deodorization (200–208°C, 3 hr) eliminated most volatiles. Some volatiles in deodorized samples were attributed to container material and antioxidants. Copyright © 1990, Wiley Blackwell. All rights reserved
