Abstract
A process for physically refining a vegetable oil comprising a step of deodourising a crude vegetable oil by steam distillation under refining conditions effective to produce a refined vegetable oil having a trans-fat content of less than 0.99 wt %. The steam is generated from water substantially free of chlorine to prevent formation of organic chlorine, particularly in the form of 2-MCPD and 3-MCPD.

(canceled)
An apparatus for physically refining a vegetable oil comprising a deodourising vessel for steam distillation of a crude vegetable oil with steam under refining conditions effective to produce a refined vegetable oil having a trans-fat content of less than 0.99 wt %, said steam being generated from water substantially free of chlorine.
A process for physically refining a vegetable oil comprising the steps of:
- (a) extracting a crude vegetable oil;
- (b) degumming and bleaching the crude vegetable oil for initial removal of impurities;
- and
- (c) deodourising a crude vegetable oil by steam distillation under conditions effective to produce a refined vegetable oil having a trans fat content of less than 0.99 wt %;
- and further comprising a chlorine reduction step.
An apparatus for physically refining a vegetable oil comprising:
- (a) a presser, operated at ambient conditions, for extracting a crude vegetable oil;
- (b) a series of vessels for degumming and bleaching the crude oil for initial removal of impurities;
- (c) a vessel for deodourising a crude vegetable oil by steam refining under conditions effective to produce a refined vegetable oil having a trans-fat content of less than 0.99 wt %;
- and
- (d) a chlorine removal stage.
