Optimization of Physical Refining to Produce Rice Bran Oil with Light
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.
In industrial production, rice bran oil is mostly refined by hydration degumming, active clay decolorization, steam deacidification and deodorization, and low-temperature freezing dewaxing. The specific method is to add 2‰~3‰ phosphoric acid and a proper amount of water to treat the crude rice bran oil at 90 °C for degumming.

Rice Bran Oil
Piironen et al. (2000) indicated that rice bran oil has the highest concentration of phytosterols of the common vegetable oils at 32.25 mg/g in crude oil and 10.55 mg/g in refined oil. More recently, Van Hoed et al. (2006) reported a concentration of 29.4 mg/g total phytosterols in crude oil and 21.5 mg/g, 19.2 mg/g, 19.1 mg/g, and 18.3 mg/g in oil that was neutralized, bleached, de-waxed,
Thus, these pretreatment steps enabled the physically refined rice bran oil to meet commercially acceptable levels for color, FFA content, and cloud point values (10–12 Lovibond units in a 1-in, cell,

1) Firstly, to pump crude rice bran oil into oil refining tank with heat conduction oil, and the temperature will reach about 70°C-80°C in one hour, then add acid or alkali to separate rice bran oil according to the acid value. After one hour’s processing and 4-6 hours deposit, then to convey soap stock to storage tank;
Phytosterols and γ‐oryzanol in rice bran oils and distillates from
Commercially available refined rice bran oil (RBO) contained high contents of phytosterol and γ-oryzanol, that is, 858–1034 and 248–887 mg per 100 g oil, respectively. Although the crude rice bran oil (CRBO) had high contents of both phytochemicals (1362–1376 mg phytosterol per 100 g and 1599–1666 mg γ-oryzanol per 100 g), physical
The expelled oil from rice bran is crude and contains components like lecithin, gums, pigments, crude resinous matter, and waxes (Thangaraju et al., 2020). Waxes generally occur in all edible oils like sunflower, rice bran, and corn, altering their physical and chemical properties along with usability. Therefore, it is essential to remove it
