摘要
以金银忍冬果实为原料,研究其色素的提取工艺及稳定性。结果表明:金银忍冬果实色素易溶于乙醇、丙酮、石油醚,是脂溶性色素。质量分数为95%的乙醇是最佳提取剂。酸、碱、光、热稳定性较好。60℃条件下色素的提取效果最佳。Na^(+)、Al^(^(3+))、Mn^(2+)、Zn^(2+)金属离子对色素的稳定性无影响,且有不同程度的护色作用。而Fe^(3+)、Cu^(2+)对色素的影响较大。氧化还原剂、食品添加剂对其稳定性影响较小。
Using the lonicera maackii fruit as raw material,extraction and stability of its pigment were studied.The results showed that:the pigment of the lonicera maackii fruit is easy to be dissolved into alcochol,acetone and light petroleum.It is a fat-soluble pigment,mass fraction 95%alcochol is the best extracting agent.The pigment has the better acid,base,light and heat stability.When the temperature is at 60℃,extractive effect is the best.The metal ions of Na^(+)、Al^(3+)、Mn^(2+)、Zn^(2+)have no effect on the pigment stability and they can protect the color of pigment in varying degrees.The ions of Fe^(3+),Cu^(2+)have great effect on the pigment.The reductant-oxidant and food additives have less effect on stability.
