Physical Refining of Membrane Ultrafiltration Degummed Rice Bran Oil

Conventional processing of crude vegetable oils is a multi-step process involving several steps. Two of the main steps in conventional processing include degumming (phosphatides by convention are termed gums) by methods that involve addition of chemicals and usage of tedious steps, and de-acidification via chemical neutralization that results in not only loss of neutral oil but generates an effluent that needs to be treated. Physical refining of the membrane degummed oil produced oil that was comparable with the market brand and matched in its quality in terms of, mainly, color and Peroxide Value. These results along with drawbacks, difficulties encountered, and scope for further investigation will form the subject text of the present investigation.
