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 ).
What is rice bran used for?
One of the most common uses of rice bran is the extraction of rice bran oil (RBO), which is mainly produced and consumed in Asian countries , where it is considered as a healthy oil, thanks to its extraordinary proprieties.
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.
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.
