After rice harvesting, the milling processes generate many by-products including husk, bran, germs, and broken rice representing around 40% of the total grain. Bran, one of the external cereal layers, contains proteins, dietary fibers, minerals, and lipids. One of the most common rice bran utilization is the extraction of rice bran oil (RBO).
What is rice bran oil?
Bran, one of the external cereal layers, contains proteins, dietary fibers, minerals, and lipids. One of the most common rice bran utilization is the extraction of rice bran oil (RBO). Among all vegetable oils, RBO presents a unique chemical composition rich in antioxidant compounds such as ¦Ã-oryzanol that provide several beneficial properties.
What is rice bran oil (RBO)?
One of the most common rice bran utilization is the extraction of rice bran oil (RBO). Among all vegetable oils, RBO presents a unique chemical composition rich in antioxidant compounds such as ¦Ã-oryzanol that provide several beneficial properties. RBO is generally extracted by exploiting hexane, a solvent toxic to the environment and human health.
How is RBO extracted from rice bran?
Obsolete technologies are generally used to extract RBO from rice bran, often exploiting hexane, a solvent toxic to the environment and humans [ 6 ]. The growing demand for this oil has led companies and universities to seek for greener and safer alternative extraction technologies.
