摘　　要：从石榴皮中提取得到了一种鞣花酸类色素,并对该色素的理化性质进行了研究,分析测试了光、热、酸、碱、氧化剂、还原剂、食品添加剂对其性能的影响。结果表明:该色素呈酸性,在λm ax=365nm存在最大吸收,其颜色随着碱性的增大而加深,对热、氧化剂、还原剂、食品添加剂以及Na+、K+稳定性好。The ellagic acid pigment was extracted from granatum , and its physical and chemical property , such as ,light ,hot ,acid , alk ,oxidizier and reducer ,food additives were studied. It turns out that this pigment is acidic ,there is the greatest absorption for 365 nm in the wavelength to pigment , the color of this pigment is strengthened with alkaline increase ,and it has good food additives- resistance and light- resistance as well as stability to Na^ ＋ .K^ ＋ ions.
