摘  要:
探讨鸡血藤红色素的最佳提取溶液,定性定量光、温度、pH值、氧化还原介质对红色素稳定性的影响。结果表明,鸡血藤红色素最佳提取溶剂为65%酸性乙醇(pH1.8),且色素为非花色苷类色素。室内自然光对色素影响不大,该红色素在20~60℃具有较好的稳定性,对氧化剂、还原剂反应敏感。

摘  要:
The red pigment was extracted from Millettia reticulata Benth and the physical and chemical properties of red pigment from Millettia reticulata Benth were investigated,the effects of light,temperature,pH value,oxide-reducing medium on pigment stability were studied.The results showed that the procedure of acid-alcohol extraction gave rather satisfactory results.The pigment does not belong to anthocyanins,and is stable below 20-60 ℃,but its resistance to oxide and reductant is not good.
