Abstract
The present invention relates to a process for treating an oil comprising a chlorophyll derivative. In particular, the present disclosure relates to an improved process for removing impurities, including chlorophyll derivatives and/or trace metals, from an oil using an adsorbent comprising a silica treated with an alkali earth metal oxide, such as magnesium oxide. The process comprises contacting the oil with the adsorbent, wherein the pH of the silica is about 7 or greater, including from about 7 to about 10. The process may further comprise contacting the oil with a polypeptide having decolorase activity or a composition comprising the polypeptide, prior to contact with the adsorbent.
