| Abstract: | Crystallization is one of common methods to refine tyrosine. In this process,the factors influencing the quality of production were so many that we had to optimize technological conditions by the orthogonal test. The result showed that high guality tyrosine could be obtained under the following conditions:solution concentration of 6%,ammonia water concentration of 5%,destination pH of 2.0,weight ratio of active carbon to active white soil of 3:1 and neuralization temperature of about 60～70℃. |
