Rice Bran Oil: Emerging Trends in Extraction, Health Benefit
An attempt was made to replace hexane with ethanol and isopropanol to extract RBO (Capellini et al., 2017) under different solvent hydration degrees (0%, 6% or 12%), using rice bran to solvent ratio (3:1) at different temperatures (50 °C to 80 °C) for 1 h.
The RBO yield was compared between solvent extraction methods utilizing hexane and isopropanol at a 2:1 or 3:1 wt ratio, extraction temperatures of 60 ⁰C or 40 ⁰C, and different extraction periods (W. Hu et al., 1996). At 60 ⁰C for 10 min, isopropanol exhibited a somewhat lower oil output (201.2 g/kg) than hexane (211 g/kg).
Evaluation of Process Parameters on Rice Bran Oil Yield in
Rice bran crude oil with less than 5% FFA is desirable for refining [8]. If FFA is more than 5%, the oil is used for soap manufacture or other industrial purposes. On top of that, it is uneconomical and unaffordable for the small rice millers to install large scale solvent extraction unit for rice bran oil production. Hence,
CO 2 -expanded hexane is used to extract phosphorus-free bio-oil from rice bran, which constitutes the main byproduct of the rice milling process, containing approximately 20–25 wt% oil. Optimal extraction conditions, namely 25 °C temperature, 5.1 MPa pressure, 0.87 CO 2 mole fraction, and 0.2 mol CO 2 -expanded hexane per gram of rice bran
Optimization of Oil Extraction from Rice Bran with Mixed
Compared with traditional solvent extraction, the peroxide value, acid value, iodine value, and fatty acid composition content of rice bran oil extracted using the new mixed solvent were close to those of n-hexane and significantly lower than those of solvent No. 6, while the content of oryzanol and total sterol increased to 2.7% and 5.1%. This
The highest percentage of oil was extracted using a 1:3 rice bran-to-solvent ratio for all the solvents, except for ethanol, in which the maximum yield was obtained using a 1:6 rice bran-to-solvent ratio. The authors identified γ-oryzanol in each experiment, even though they did not quantify the amount.
Extraction and utilization of rice bran oil: A review
solvent extraction using hexane is the most popular used conventional method for commercial ... rice bran oil; extraction of RBO; utilization of RBO ... 42.7-99.9% yield of oil from rice bran using
The extraction was performed with a constant solvent flow of 20 kg/h for 3 h, filling the extractor with 1 kg of rice bran and metal Raschig rings to promote the solid and solvent contact. SFE pressure (P) and temperature (T) conditions were, respectively, 300, 350 and 400 bar, and 40, 50 and 60 °C, according to the experimental design
Rice Bran Stabilisation and Oil Extraction Using the
These results may be related to the cell wall disruption that occurred during extraction; on the other hand, they may reflect the difference between extraction techniques, as the solvent extraction with isopropanol before the RB analysis by HPLC is less efficient in terms of oil yield than the MAE extraction, as verified in the previous
In order to improve the extraction ratio of rice bran oil, a single-factor experiment and response surface methodology with a central composite design were used to determine a new mixed solvent and the optimal extraction conditions of the mixed solvent. The effects of solid–liquid ratio, extraction time, extraction temperature, and oscillation speed on the extraction ratio were investigated
