  • 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.
  • What materials were used to make a sunflower extraction experiment?
  • All experimental determinations were made with sunflower expanded material, known as “collets”, which were kindly provided by a local factory. Collets were stored in polyethylene containers with screw caps in the dark at 4 °C until used in the extraction experiments.
  • Does ethanol extract oil?
  • Some authors point out the lower selectivity of ethanol towards oil, with the consequent extraction of other compounds such as phosphatides, polyphenols, pigments and soluble sugars (Hron et al., 1982, Hron et al., 1994, Sineiro et al., 1996), which is in agreement with our results.
