Rice bran oil (RBO) is unique among edible vegetable oils because of its unique fatty acid composition, phenolic compound (γ-oryzanol, ferulic acid) and vitamin E (tocopherol and tocotrienol). It has become a great choice of cooking oil because of its very high burning point, neutral taste and delicate flavour.
How is rice bran oil extracted?
There are about 15–20% crude oil in rice bran; normally, the rice bran oil is extracted by pressing or solvent extraction methods, such as supercritical carbon dioxide extraction and enzymatic extraction, and then refined by decolorization, deodorization, or other processes.
What is rice bran oil (RBO)?
This lipidic fraction can be extracted to obtain rice bran oil (RBO), a high value-added product with unique health properties as a result of its high concentration in γ-oryzanol, a powerful antioxidant mixture of bioactive molecules.
What are the technologies of rice bran oil?
After that, the fatty acid composition, bioactive compounds, and the processing technologies of rice bran oil are described and the refining technology of rice bran oil (degumming, deacidification, dewaxing, etc.) as well as the technologies to remaining the bioactive compounds in rice bran oil are introduced.
What is rice bran (RB)?
Rice bran (RB), the outer brown layer of rice, is one of the main by-products during milling. It is a rice source of rice-bran oil (RBO) with good fatty acid profile and phytonutrients like oryzanols, tocopherols, tocotrienols, phytosterols, and importantly dietary fibers.
What is rice bran used for?
Rice bran is a byproduct of rice milling that is removed during the milling process. Rice bran is rich in nutrients, including fiber, protein, vitamins, and minerals. Rice bran is used as cattle feed, edible oil, and as a food ingredient. Ohmic, microwave, infrared, and extrusion are various rice bran processing methods.
