摘要
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 aflatoxins from these solvents. Enzyme-linked immunosorbent assays method and a high-performance liquid chromatography method with fluorescence detector were used to determine the toxins in the feed and eluates from the adsorption columns. Experimental data indicate that montmorillonite is highly effective for adsorptive aflatoxin removal. Adsorption data with neutral alumina and silica are also presented. Ethanol and ethanol-based miscellas, obtained from alcoholic cottonseed extractions were spiked with aflatoxins for this investigation.
