A novel process for physically refining rice bran oil through
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. The simultaneous degumming and dewaxing of the crude oil with a solution of water and CaCl2, followed by crystallization at a low temperature (20°C), facilitated precipitation of the hydratable and nonhydratable
This process concerns a few types of oils rich with waxes, such as rice bran, canola, corn germ oil, sunflower , and olive pomace . The dewaxing process includes three main processing steps. In the first one, the bleached oil should be heated to 328°K (55°C) to make sure the oil is completely liquid.
Optimization of Physical Refining to Produce Rice Bran Oil
Crude rice bran oil (RBO) is rich in valuable minor components such as tocotrienols, phytosterols and γ-oryzanol. These compounds are well preserved during physical refining, but in current industrial practice, RBO is mostly refined chemically because this results in a lighter color. However this process removes most of the γ-oryzanol.
Physical refining of rice bran oil (RBO) with acidity between 4.0 and 12.4% has been investigated in relation to degumming and dewaxing pretretments. It appears that physical refining after combined low-temperature (10°C) degumming-dewaxing produces good-quality RBO with respect to color, free fatty acid, oryzanol, and tocopherol content.
A novel process for physically refining rice bran oil through
A new process for the physical refining of rice bran oil through combined degumming was developed on a laboratory scale. Studies were conducted to improve quality of rice bran oil by degumming to make it edible grade.
Results showed that the physical refining process was able to preserve 97% of γ-orizanol, and its presence improved the oxidative stability of the oil comparing with the commercial rice bran oil

Refining of Rice Bran Oil
Rice bran oil is normally refined by physical method to keep the Oryzanol in the refined oil. In chemical process Oryzanol get destroyed by alkali. For the physical refining of Rice bran oil following processing steps takes place. Degumming of Rice Bran Oil a. Degumming eliminates phospholipids so as to enhance its physical stability.
