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。

Abstract: 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.

Key words: Millettia reticulata Benth, red pigment, physical and chemical properties, stability
