Abstract: In order to explore the blanching process of Capsella bursa- pastoris , the author used different blanching methods to analyze chlorophyll content, vitamin C content and relative activity of peroxidase. The results showed that, with blanching temperature rise or time prolonged, the content of chlorophyll, shepherd’s purse vitamin C content and POD enzyme activity were all decreased. The use of response surface methodology (RSM) bleaching parameters on the shepherd’s purse hot was optimized, the blanching temperature of 98℃ and blanching time of 71.34 s was the best combination, in which the content of chlorophyll was111.70 mg/100 g, relative activity of POD enzyme was 8.20% and the content of vitamin C was 26.33 mg/100 g.
