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 ).
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.
What is enzyme assisted extraction of rice bran oil?
Table 3. Enzyme assisted extraction of rice bran oil and their corresponding yields. The advantages of enzyme assisted extraction technique compared to conventional solvent extraction methods includes reduced time of extraction, minimized solvent usage and increased yield and quality of product.
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 nowadays, but recently, the preferred industrial technique for commercial uses is extraction using non-polar solvents, such as hexane [ 6 ].
