Abstract
Chlorophyll derivatives in canola oil were analyzed quantitatively by reversed-phase high-performance liquid chromatography without any pret reatment. The main components were pheophytin (pheo) a and b and pyrop heophytin (pyro) a and b. The factors affecting the types and concentr ation of chlorophyll derivatives in oil have been investigated during seed preparation, expelling, extraction, degumming and alkali-refining processes. Bleaching tests of alkali-refined canola oil with activate d earth indicated the adsorption of each derivative to decrease in the following order: pheo a > pyro a >> pheo b > pyro b. In bleaching wit h activated carbon, however, the following order was observed: pyro b > pheo b > pheo a > pyro a.
