An ecofriendly approach to process rice bran for high quality rice bran oil using supercritical carbon dioxide for nutraceutical applications

Stability of rice bran oil extracted by SFE and soxhlet methods during accelerated shelf-life storage

“…From Table 2 it is clear that no significant differences were observed in the fatty acid compositions among the oils obtained by SFE HO, SFE LO and SOX extraction methods. These findings are in good agreement with those reported by Balachandran et al (2008).…”

Physicochemical and Antioxidant Properties of Rice Bran Oils Produced from Colored Rice Using Different Extraction Methods

“…The rice bran sample was loaded into the extraction vessel, and filled with glass beads at the bottom and top of the cell. The cell was placed in the heating chamber to maintain the operating temperature 12 .…”

“…There were seven fatty acids found in the profiles including Tetradecanoic Myristic, C14:0 , Hexadecanoic Palmitic, C16:0 , cis-9-Hexadecenoic Palmitoleic, C16:1 n7 , Octadecanoic Stearic, C18:0 , cis-9-Octadecenoic Oleic, C18:1 n9 , cis-9,12-Octadecadienoic Linoleic, C18:2 n6 and cis 12, Linolenic, C18:3 n3 . The major saturated fatty acids found in the samples were myristic, palmitic and stearic acids with the concentration of 0.29-0.42, 17.87-20.57 and 2.18-2.65 g/100 g oil, respectively.…”

Supercritical CO₂ Extraction of Rice Bran Oil –the Technology, Manufacture, and Applications

“…The SC-CO 2 oil contained little amount of phosphatides, wax and pro-oxidant metals Fe and Cu , and the color quality of the oil was far superior to that of hexane-extracted oil. The RBO phytochemical contents under the optimum conditions of 50 MPa, 60 for 90 min were up to 1,800 ppm of tocols, 19,000 ppm of sterols, and 11,000 ppm of oryzanols 52 . On the other hand, the stabilities of RBOs obtained by SC-CO 2 extraction and hexane Soxhlet method were studied during accelerated shelf-life storage 53 .…”

“…Different varieties of rice bran also affect the quality of RBO. Sookwong et al 44 extracted RBOs from various rice bran samples, including pigmented and non-pigmented glutinous and nonglutinous varieties, using SC-CO 2 , and found that the 52 that RBO extracted with SC-CO 2 had an oil yield comparable to that extracted with hexane 22.5 . The SC-CO 2 oil contained little amount of phosphatides, wax and pro-oxidant metals Fe and Cu , and the color quality of the oil was far superior to that of hexane-extracted oil.…”
