Abstract Cottonseed was extracted with hexane and acidic hexane (hexane that contained 2–25% acetic acid) and properties of the resultant miscellae and meals were compared for each sample. Pigment contents were only slightly larger in acidic hexane miscellae. Settling rates of marc particles were much faster through acidic hexane miscellae. Nutritional analyses of the extracted cottonseed meals indicated that protein efficiency ratios, digestibilities, epsilon amino‐free lysine values and free and total gossypol contents were essentially identical with each type of solvent. Aflatoxin contents of similarly treated, contaminated peanuts did not change. The results are discussed with regard to previous findings concerning the more thorough extractions of lipid from oilseeds with acidic hexane than with hexane alone.
