Open publisher page 0 citations

Abstract

The extraction and stability of Yellow pigment in Chinese Globle Flower were studied.The experimental results showed that the stability of this pigment is good when pH is within 2～7; It has not better endurance capability against oxidizing agent(H2O2) and reducing agent(Na2SO3); while NaCl and saccharine have little influence on its stability,and it is not react too much with various metal ions; the heat performance of the pigment is good when under 60?℃ and light will destroy the pigment.
