Abstract In the process of resoluting methionine with enzyme,L-Met is isolated by ion-exchanger,the mainly remnant will be N-acetyl-D(L)-Met.After the racemic of the remnants,some N-acetyl-D-Met will be transformed into N-acetyl-L-Met,then they can be reused as the resolute substrate.In this paper,considering the not high yield and the poor quality of the products in the factories,we designed orthogonal experiments to analysis the factors which affect the racemic process.The appropriate conditions were got,the quality and the yield were improved as well.
