Mar 01, 2016 · The ultrasound-assisted aqueous extraction of rice bran oil. With regard to quality, the oil extracted by ultrasound-assisted aqueous process had a lower content of free fatty acid and lower color imparting components than the hexane-extracted oil. Also, effect of parboiling of paddy on hexane and ultrasound-assisted aqueous extraction was studied.
Mar 01, 2016 · As shown, at ultrasound-assisted aqueous extraction at pH = 12, temperature of 45 °C, agitation speed of 800 rpm, agitation time of 15 min, ultrasound treatment time of 70 min and ultrasound treatment temperature of 25 °C, the yield of rice bran oil was close to the yield of oil extracted by hexane Soxhlet extraction.
The results showed that the yield of rice bran oil at ultrasound-assisted aqueous extraction was close to the yield of oil extracted by hexane Soxhlet extraction.
Jun 29, 2012 · Oil can be extracted from rice bran by mechanical expression and solvent extraction. The minimum oil content to which oil cake can be reduced by mechanical expression is about 12 %. But the solvent extraction method leaves less than 1 % oil in the extracted meal.
The results showed that the yield of rice bran oil at ultrasound-assisted aqueous extraction was close to the yield of oil extracted by hexane Soxhlet extraction. This result implied that the yield of rice bran oil was significantly influenced by ultrasound.
Enzymatic water-extraction of oil and proteins from rice bran was studied in a laboratory-scale set-up. The effects of the following enzymes – Celluclast 1.5L, hemicellulase, Pectinex Ultra SP-L, Viscozyme L, Alcalase 0.6L and papain – on oil and protein extraction yields, and the level of reducing sugars in the extract were investigated.

2.1. Aqueous extraction of rice bran oil. RBO was extracted from raw rice bran using distilled water as the solvent. Rice bran and water were mixed in a container to the required bran to water ratio and the mixture was continuously stirred for a specific time at constant temperature and pH.
Oct 18, 2016 · Pomegranate seed oil can be extracted with various extraction methods. Kalamara et al.  extracted pomegranate seed oil using the direct ultrasound-assisted method with a yield varying between 15.66 and 18.16 g oil/100 g seeds at extraction time of 10 min, whereas Tian et al.
