Abstract
The present invention relates to methods of producing oil raw material for HVO production from vegetable oil which has been processed by an enzyme catalysed hydrolysis process and separation to reduce the content of phosphorous.
Claims19
A method of purifying oil from vegetable oil feedstock for hydrotreated vegetable oil (HVO) production, said method comprising steps of:
- (a) mixing the vegetable oil feedstock with water;
- (b) hydrolyzing the vegetable oil feedstock mixture of step a) with a composition comprising a polypeptide having phospholipase activity and a polypeptide having lipase activity;
- (c) separating the light and heavy phase, wherein the free fatty acid of the light phase after separation is >50% and
- (d) subjecting the light phase to bleaching or distillation.
