An improved process for the production of oryzanol enriched fraction from rice bran oil soapstock

The present invention relates to a process for the production of oryzanol enriched fraction from rice bran oil soapstock; the present invention particularly relates to saponification, dehydration and leaching of rice bran oil soapstock for production of oryzanol enriched fraction. Conventional saponification reactions are carried out at elevated temperatures and for long times. In this invention, it is achieved at low temperature and short time (LTST) process which enable to avoid the possible degradation of the product of interest (oryzanol). The increase in interfacial area by micromixing (by the shear force in colloidal mill) is the novelty employed here to perform the saponification pretreatment of soap stock at mild operating conditions that is, lower temperature for short duration.
