the practical feasibility of using methylene chloride to extract oil, aflatoxin and gossypol simultaneously from cottonseed flakes was demonstrated in a 56-hr experimental run using a pilot-scale, continuous extractor. nine different trials varying in extraction time, solvent:flake ratio, flake preparation method and blending with 5 ethanol were evaluated. residual oil contents were lower than typically achieved in extraction with hexane. aflatoxin contents of the meals were reduced by 73-92 of the level in cottonseed meals, making possible the upgrading of a large portion of cottonseed meal that otherwise would exceed current action levels the oil was refined and bleached to acceptable quality standards, and no residual aflatoxin was detected in alkali-refined oil.
