The extraction and stability of red pigment from grape skin were studied. The optimum extraction conditions of red pigment from grape skin were showed as follows: the ethanol concentration was 70%; the extraction temperature was 70°C; the extraction time was 70 min. Under these conditions, the absorbency of extraction liquid of red pigment from grape skin was about 0.8. The red pigment from grape skin had good resistance to light decomposition and heating. Heating and lighting had little effect on the pigment stability.
