By weight, rice bran has 17% oil content. After the refining process, the refined rice bran oil weighs only 12% of the rice bran raw material.

The extracting process starts with raw material preparation. Rice bran is first screened. It is then heated by steam at temperature higher than 100 degrees Celsius to stop Lipase hydrolysis in rice bran prior to extraction.

Advanced extracting technology and techniques were developed with technical assistance from German and Belgian engineers in order to come up with Crude Rice Bran Oil that is high in Vitamin E and Oryzanol. The Crude Rice Bran Oil is forwarded to the refining process for purifying and packing.

In 2004, the extracting process is GMP (Good Manufacturing Practice) and HACCP (Hazard Analysis and Critical Control Point) certified by the Department of Livestock Development (DLD), the Ministry of Agriculture and Cooperative, Thailand. Moreover, it is also ISO 9001:2000 certified by SGS (Thailand) Co., Ltd.
