Abstract
The paper Discuss as the degossypoling effects by using FeSO4,Ca(OH)2,H2NCONH2,Ca(OH)2 and FeSO4 Compounded from cottonseed cake,and the cottonseed cake which were deal with four chemical methods in the different pH values has different gossypol content.The results indicate:the degossypoling cottonseed cake dealt with by the four chemical methods,along with pH value reduction,the free gossypol(FG)increased significantly,and this showed the bound gossypol(BG)has become FG in the acid,and the BG in the degossypol cottonseed cake dealt with by these four chemical methods has unstable property.
