Optimization of Physical Refining to Produce Rice Bran Oil

  • Can degumming & dewaxing be used for rice bran oil refining?
  • A new process for the physical refining of rice bran oil through combined degumming and dewaxing was developed on a laboratory scale and then demonstrated on a commercial scale.
  • What are the steps in a rice bran oil refining process?
  • The steps in the process of refining rice bran oil are given in Fig. 14.1. The first step in the refining process with crude rice bran oil is usually dewaxing or winterizing. However, for other vegetable oils, the dewaxing step can be done at different times in the refining process.
  • Why is parboiled rice bran a good choice for dewaxing?
  • It was observed that oils obtained from parboiled rice bran have much easier operation compared to raw bran. The temperature of the place also has an influence on dewaxing parameters. Another important factor is the moisture content of the oil.
  • Can a nonporous membrane be used for degumming and decolorizing crude rice bran oil?
  • Efficacy of nonporous membrane has been evaluated for simultaneous degumming, decolorizing and dewaxing crude rice bran oil (CRBO). Membrane processing of CRBO showed that phospholipids (PL) were almost completely rejected (>99%) by nonporous membranes in both industrial and laboratory-prepared samples.
