The reduction of free gossypol in cottonseed flakes during solvent extraction

Lionel K. Arnold, William G. Juhl

Abstract

Conclusions Extraction with trichloroethylene was found to be an effective method of reducing the free gossypol content of flaked cottonseed meats. The reduction was found to be a function of both extraction temperature and residual extractables in the extracted meal. Because of the low temperatures involved the meal produced by this method has a higher soluble protein content than a meal in which the free gossypol is reduced by heat treatment.
