海红果红色素的理化性质

Factors influencing the stability of the red pigment extracting form Haihongguo fruit,a natural fruit,were investigated in this paper.The results showed that the pigment was stable in acid,under the light and heat condition.The food additions such as starch,carbohydrate,ascorbie acid,sucrose,glucose sodium benzoate ect.,have no bad influence on the color quality of the pigment,so did the reace element for human body such as K+,Na+,Ca2+,Zn2+,ect.,However the Fe3+,Sn2+,H2O and Na2SO3,have redox reaction with the pigment and change its color.The exaction of red pigment in the Haihongguo Fruit may provide the new sources for the food addition.
