PROCESS FOR TREATING A PLANT OIL COMPRISING HYDROLYSING CHLOROPHYLL OR A CHLOROPHYLL DERIVATIVE AND INVOLVING PARTIAL CAUSTIC NEUTRALISATION

摘要

In one aspect there is provided a process for treating a plant oil, comprising contacting the oil with water and an enzyme which is capable of hydrolysing chlorophyll or a chlorophyll derivative, thereby generating one or more enzyme reaction products; wherein the enzyme is contacted with the oil at a pH of 4.0 to 7.0; adjusting the pH to 7.5 to 7.7; and separating an aqueous phase containing the enzyme reaction products from the oil.
