Title:
PROCESS FOR THE PRE-TREATMENT OF VEGETABLE OILS FOR PHYSICAL REFINING
Document Type and Number:
WIPO Patent Application WO2003102118
Kind Code:
A3
Abstract:
The present invention relates to a simple and economically attractive process for the pretreatment of vegetable oils which involves (a) enzymatic degumming with commercially available phospholipase A1 from the sources like Aspergillus oryzae microorganism, (b) bleaching of the enzymatically degummed oil using bleaching earth and activated carbon, and (c) dewaxing (in case of rice bran oil) of degummed and bleached oil at lower temperature to obtain oil with less than 5 ppm of residual phosphorus which is amenable for physical refining.
