Extraction of sunflower oil using ethanol as solvent
Isopropanol and ethanol are the most promising solvents for the oil extraction from cottonseed (Abraham et al., 1988, Hron et al., 1994), sunflower seed (Sineiro et al., 1998) and soybean (Baker and Sullivan, 1983, Rittner, 1992). Ethanol is a worthy candidate to be studied as alternative solvent because it is cheap and it can be produced by fermentation from a large variety of biological materials using simple technology, and therefore labeled as "natural" or "biorenewable".
