Rice Bran Oil: Emerging Trends in Extraction, Health
30% of rice bran improved the mechanical properties of the packaging film in terms of hardness value. Advances in RBO extraction strategies, like super/sub-critical CO2, microwave-assisted subcritical H2O, and ultrasound-assisted aqueous extraction methods, could help to make RBO an important substrate for the food and non-industries.
