Abstract
The present invention relates to a process for treating an oil comprising a chlorophyll substrate, the process comprising contacting the oil with a polypeptide having decolorase activity or a composition comprising the polypeptide, wherein the polypeptide is selected from the group consisting of: a. a polypeptide which has at least 80% identity to amino acids 1 to 318 of SEQ ID NO: 1; and, b. a polypeptide encoded by a nucleic acid sequence that has at least 80% identity to the nucleic acid sequence of SEQ ID NO: 2.
Claims29
A process for treating an oil comprising a chlorophyll substrate, the process comprising contacting the oil with a polypeptide having decolorase activity or a composition comprising the polypeptide, wherein the polypeptide is dosed into the oil in an amount of 1 to 50 U/gram oil, wherein the treatment reduces the total concentration of chlorophyll substrates in the oil by at least 5% by weight, compared to the total concentration of chlorophyll substrates in the oil prior to treatment.
A process for treating an oil comprising a chlorophyll substrate, the process comprising contacting the oil with a polypeptide having decolorase activity or a composition comprising the polypeptide, water, and an additional enzyme, at a pH of from 4 to 8;
- and stirring the resulting oil for from 0.5 to 24 hours, wherein the polypeptide is dosed into the oil in an amount of 1 to 50 U/gram oil.
