Effect of Gamma‐Radiation on Gossypol in Cottonseed Meal

ABSTRACT The effect of gamma–radiation, in the range 5–30 KGy on free, total and pure gossypol was investigated in an attempt to reduce or eliminate gossypol from cottonseed meal using different solvent systems. Maximum reduction in gossypol concentration was attained at a dose of 25 KGy of gamma‐radiation with chloroform as a solvent, a spectrometric method was used for analysis. The reductions attained for pure, free and total gossypol were found to be 96%, 60% and 80%, respectively.
