Rice Bran Oil Extraction Machine From in Congo

How is rice bran oil extracted?
Rice bran oil (RBO) can be extracted chemically using solvent or mechanically by hydrolytic pressing. Solvent extraction covers a wide range of techniques, including traditional solvent extraction, ultrasound assisted extraction, supercritical fluid extraction, and enzyme assisted extraction (Fraterrigo Garofalo et al., 2021a ).
How is RBO extracted from rice bran?
The Japanese were the first to extract RBO from rice bran using the hydraulic press technique, which is still used nowa-days, but recently, the preferred industrial technique for com-mercial uses is extraction using non-polar solvents, such as hexane .
Can -oryzanol be extracted from rice bran oil?
All the here reported green extraction techniques allow a high-quality rice bran oil and high concentrations of γ-oryzanol to be obtained and show comparable yields with the extraction methods that employ hexane.
Is rice bran oil a solventless extraction method?
This review has highlighted that despite the efficiency in the extraction of rice bran oil, some solvents are toxic. The future direction should therefore focus on green extraction methods in order to address the need for environmental sustainability. The solventless methods or the methods that use water as a solvent are therefore encouraged.
