Abstract: This paper reported the producessing technology on preparing complex amino acids from plant spent protein resources-cottonseed cake and rapeseed cake hydrolyzed by HCl, and the optimum parameters were: the HCl concentration 4mol/L, the ratio of cake to water is1:4(g/g), reacting 9h under 126℃ with added pressure. The results showed that the hydrolysis degree of cottonseed cake and rapeseed cake are up to 11.34% and 13.96% respectively, and the toxic components of cottonseed cake and rapeseed cake could be reduced or wiped off .
