Sodium zinc chlorophyllin was extracted from tea leaves,and its optimal technological condition and stability were studied. The results showed that the optimal zinc reaction condition was: the weight ratio of tea powder to ZnSO4·7H2O is : 5:7.1, the reaction temperature is 60℃,the reaction time is 2βh,the yield of the pigment is 2.1%. In addition, sodium zinc chlorophyllin has stable character on wate- solubilization, heating, oxidizing, reducing, raying(pH:2.8~12.78),and it would not be influenced by some common food additives and metal-salts.
