Abstract: This paper studied the stability of the pokeberry fruit pigment. The result shows that the stability of the pokeberry fruit pigment has influence in various degree of temperature, pH, oxidant, reducing agent, illumination, metal ion, additive and so on. The having more obvious in influence pigment stability of high temperature, sunlight, sulphurous acid of hydrogen sodium, Cu2+, Fe3+.

Key words: pokeberry fruit, pigment, stability
