Sep 1, 1992Abstract Ethanol (EtOH) is being evaluated as an alternate solvent to hexane for the extraction of glanded cottonseed. Hot EtOH, needed for efficient oil and aflatoxin extraction, binds gossypol to protein. However, this binding can be minimized by acidifying aqueous EtOH with a tribasic acid, such as phosphoric or citric.

Physical removal of aflatoxins from cottonseed by solvent extraction with ethanol or isopropyl alcohol is technically feasible. These solvents used in the removal process are recycled to extraction systems after regeneration by distillation. However, distillation is costly due to high latent heat of the solvents. Adsorption techniques have been explored as a method to remove

Can gossypol be extracted from cottonseed meal?
To test for the possibility of extracting gossypol from cottonseed meal, commercial meal was extracted with solvent, water, and acid. The solvents used were acetone and ethanol, both GRAS (generally considered as safe) for use in food processing and capable of dissolving gossypol.
How do you extract gossypol?
Damaty and Hudson (1975) proposed a multi-step extraction process, first extracting the oil with hexane, then rupturing the pigment glands by the addition of aqueous acetone, followed by gossypol extraction with anhydrous acetone. Meal total gossypol levels of 1 g/kg were reported by this method.
Does ethanol remove gossypol?
Extractions conducted without acid were ineffective at removing gossypol, which differs somewhat from the prior report by Saxena et al. (2012) that noted a 60% gossypol reduction by extraction with ethanol.
How does gossypol extraction differ from acetone extraction?
Gossypol extraction occurred much faster in the ethanol-based extractions than it did in the acetone-based extractions. Treated meals tended to retain phosphorus but most of this could be removed by conducting a final water wash. Water washing also removed hydrophilic components resulting in reduced product yields but increased protein levels.
How much hexane does gossypol produce?
This process produced meal fractions with between 0.3 and 4 g/kg of total gossypol, compared with 14.8 g/kg obtained by a more traditional hexane extraction.
Which solvent is used to catalyze the hydrolysis of protein-bound gossypol?
Phosphoric acid and water were included in the solutions to catalyze the hydrolysis of protein-bound gossypol. Both solvents were effective at reducing the total gossypol level in meal to between 5% and 10% of its initial value. Gossypol extraction occurred much faster in the ethanol-based extractions than it did in the acetone-based extractions.
