：The manufacture processing of tea green pigment — sodium-zinc chlorophyllin (TGP-2) was studied by using expectant function approach for simultaneous optimization of several variable levels. The results showed that the effect of heating time was the most noticeable, then the concentration of ZnSO4,temperature, and pH successively. The optimum of preparation process was 3.0 pH, 72.8℃, with 21.5% of ZnSO4 concentration for 89.6βmin, and the efficiency of yield could reach 0.69%.
