- ... Analyses of commercial crude soybean oils showed a highly significant correlation of 0.74 between free fatty acid and Fe content. Poor flavour characteristics exhibited by finished oils extracted from damaged beans may be caused in part by a higher free fatty acid and related higher Fe content in crude oils. Source of the increased Fe appears to be both damaged beans and steel processing equipment ...

- ... Hydrogenation of crambe oil, mainly an α,α'-dierucoyl triglyceride, in the presence of Cd promoted copper-chromite provides long chain waxes being sought as sperm whale oil replacements. GLC and GC-MS analyses of secondary products indicate, however, that reduction proceeds rather differently from Adkins-type hydrogenations of triglycerides over copper-chromium oxide catalysts. Mono- and diunsatur ...
