Abstract

The stability of pigment from grape peel was studied.The results showed that acidity was a factor which did more influence on its stability and an obvious effect in increasing the color was appeared,low temperature was beneficial to saving the pigment,long time sunshine would make pigment gradual to decline.Metal ions of Fe3+and additives of H2O2did a more influence in the stability of pigment.Aqueous solution vitamin C,cane sugar aqueous solution,the sodium benzoates did a less influence in the stability of pigment.
