| Abstract: | This study mainly reports the influence of acidity, heat, light, amylum, carbohydrate,ascorbic acid,benzoic acid natrium and metal ion on the purple pigment's stability of Nopalxochia ackermannii. The results are as follows:the pigment is stable in acidity and neutrality;the light and heat degrades pigment to a certain extent ;the amylum,carbohydrate, ascorbic acid,Na+ and Zn2+ have no harmful effects. No benzoic acid natrium,Fe3+,and Cu2+ have certain effects on it. |
