Abstract: The extraction,physical and chemical property of chestnut shells planted brown pigment in Xiuyan of Anshan of Liaoning Province were studid.Its stability experiment shows that it is a kind of water-soluble pigment and has certain light and heat stability. When pH is form 3 to 9, the stability of pigment is good. This pigment has endurance ability to oxidizer H2O2 and reductive Na2SO3. The sodium benzoate, ascorbic acid and phosphate greatly affect pigment stability.

Key words: chestnut shells: natural pigment, stability
