Important Factors in the Process of Producing I--Cystine by the Method of Hydrolyzing Hair

This article has intrduced a new technique of producing l-cystineby the method of hydrolyzing hair with a yield rate of 6～ 7%,andanalyzed several important factors which will have an effect on the yield rate These factors include hydrolysis temperature hydrolysis- time the amount of active carbon used in the period of decolorization neutralization time concentration of hydrochloric acid etc On the basis of analyses the author has discussed the control methods and proposed more appropriate process control parameters The techjque is in adva - ncement in present China
