Ethanolic extraction of sunflower oil in a pulsing extractor
Oil extraction by ethanol from partially defatted prepressed sunflower seeds in pulsed and nonpulsed extractors was compared. The oil yield was increased by 8.7% after short extraction periods (up to 6.06 residence times) with a pulsing flow, which was probably due to reduction in the axial dispersion that induces a greater concentration gradient between the miscella surrounding the solid and ...
The previous year, Baümler et al. (2016) already investigated the differences in the recovery of tocopherols from sunflower oil after extraction with hexane and ethanol at two different ...

This work demonstrated the feasibility of using ethanol as an alternative solvent to hexane in the oil extraction from sunflower collets. Oil extraction was described by modified nonlinear diffusion models derived from Fick's second law, which involved two parameters: A, associated with the portion extracted during the washing stage, and B ...
Effect of solvent hydration and temperature in the
The equilibrium data were investigated using real systems prepared by mixing the degummed sunflower seed oil with ethanol containing different levels of water, from 0% to 29% by mass, in different oil:solvent mass ratios (2:1, 1:1, 1:2) at different temperatures (10.0, 25.0, 60.0 ± 0.1 °C). It is important to emphasize that each experimental ...
The effect of ethanol addition to supercritical carbon dioxide (SC-CO2), up to 20%, on sunflower seed oil extraction over the range of 150 to 350 bars and 42 to 80°C was studied. A nonrecirculating home-made bench-scale system was used as extraction equipment. The oil-SC-CO2-ethanol mixture was reduced to atmospheric pressure in a test tube, where two phases, oil and ethanol, were obtained ...
High Pressure Extraction as a Green Alternative to the
In the extraction of sunflower oil by ethanol, the effective diffusion coefficient (De) for tocopherols is higher than that of phospholipids (3.950 10 −9 and 2.596 10 −9 m 2 /s, respectively), independent of the temperature in the analyzed range, in addition to this, both the sugar mass transfer rate and the extraction yield increased with ...
Oil effective diffusivities were 9.94 10−10 at 50 °C and 3.11 10−9 m2/s at 60 °C. From the point of view of the quality of the obtained products, this work demonstrated the feasibility of using ethanol as an alternative solvent to hexane in the oil extraction from sunflower collets.
- Can ethanol extract oil from sunflower collets?
- Ethanol extracts less crystallizable waxes and more tocopherols and phospholipids. Ethanol showed great ability of extracting sugar, mainly raffinose and sucrose. The ethanolic extraction of oil from sunflower collets was studied and compared with previous data where hexane was used as extraction solvent.
- Can ethanol extract tocopherols from sunflower oil?
- The previous year, Baümler et al. (2016) already investigated the differences in the recovery of tocopherols from sunflower oil after extraction with hexane and ethanol at two different temperatures (i.e. 50 and 60 ºC) and showed a higher recovery of tocopherols when extracting the oil at 60 • C.
- How to extract sunflower oil?
- An ordinary method in extracting sunflower oil includes preparation of seed and mechanical extraction . Since no type of solvent and no other processing are involved in the production of cold-pressed oil, rather than filtering and pressing, it is more important for the market. ...
- What is the industrial process of extracting sunflower oil?
- In recent decades, the industrial process of extracting oil has not been modified considerably; however, several practical improvements in optimization and better control have been noticed . An ordinary method in extracting sunflower oil includes preparation of seed and mechanical extraction .
- Can ethanol be used as an alternative solvent to hexane?
- From the point of view of the quality of the obtained products, this work demonstrated the feasibility of using ethanol as an alternative solvent to hexane in the oil extraction from sunflower collets. Dear Author, Please, note that changes made to the HTML content will be added to the article before publication, but are not reflected in this PDF.
- Can ethanol extract lipids from sunflower seeds?
- Finally, biodiesel layer was washed with excess hot water to remove unreacted components, dried, and collected the biodiesel (Baümler et al. 2016 ). ... ... Baümler et al. reported that the capacity of ethanol to extract lipids from sunflower seeds was comparable with that of nonpolar n-hexane.
