the ultrasound-assisted aqueous extraction of rice bran oil

  • The Ultrasound-Assisted Extraction of Rice Bran Oil with n

    Rice bran oil (RBO) is one of edible oil which widely used in chemical, pharmaceutical, and food industries due to its unique properties and high medicinal value. RBO obtained by ultrasound-assisted extraction using n-hexane as solvent. This present study aims to determine the ideal bran to solvent ratio to obtain the highest extraction yield using optimal temperature.
