Journal of the American Oil Chemists Society. The lipid fraction of the deep water fish species orange roughy Hoplostetbus atlanticus , black oreo Allocyttus sp. The component acids and alcohols of the wax ester fraction were analyzed by gas liquid chromatography and compared with those of jojoba and sperm whale oils. Orange roughy oil was refined and deodorized and its chemical, physical and mechanical properties were determined. Hydrogenation of orange roughy oil produced a range of white crystalline waxes with melting points between 34 and 66 C. The characteristics of these waxes were very similar to those of hydrogenated jojoba oil and spermaceti.
