【摘要】 研究了金莲花黄色素的提取性能及其稳定性,并对提取条件进行了优化实验.实验结果表明,金莲花色素易溶于丙酮,属于脂溶性色素;在pH=2～7时,金莲花色素的稳定性较好;氧化剂(H2O2)和还原剂(Na2SO3)对其稳定性有影响,氯化钠、蔗糖介质对色素的稳定性影响不大,多种金属离子对其影响不显著;60℃以下色素的热稳定性较好,光对色素有降解作用.更多还原

【Abstract】 The extraction and stability of Yellow pigment in Chinese Globle Flower were studied.The experimental results showed that the stability of this pigment is good when pH is within 2～7; It has not better endurance capability against oxidizing agent(H2O2) and reducing agent(Na2SO3); while NaCl and saccharine have little influence on its stability,and it is not react too much with various metal ions; the heat performance of the pigment is good when under 60?℃ and light will destroy the pigment.更多还原
