Rice bran oil is obtained by extraction of rice bran, which is a by-product of the rice milling industries. The solvent extraction process of rice bran oil involves the following steps:

Rice Bran Raw Material Preparation: Rice bran is obtained during the milling process of rice. It is the hard outer brown layer of rice called chaff or rice husk.

Extraction: This is the main step where the oil is extracted from the rice bran. During the extraction process, the solvent penetrates into the rice bran granules and combines with the oil, which diffuses from the rice bran granules into the solvent. The most common solvent used in this process is hexane. However, due to its toxicity and environmental impact, efforts are being made to find green, non-petroleum-derived alternatives.

Refining: After extraction, the oil undergoes a refining process to remove any impurities.

The extracted oil is known for its high smoke point and mild flavor, making it suitable for high-temperature cooking methods such as stir frying and deep frying. It also has numerous health benefits due to the presence of a unique antioxidant known as oryzanol.
