摘  要:
对萝卜红色素进行醚化分子修饰,采用正交实验确定了最佳的反应条件和色价,并比较了化学修饰前后萝卜红色素的稳定性。结果表明:以蒸馏水作为溶剂,物料比为2:5,在0℃下反应35min,可获得色价高,稳定性较好的修饰后的萝卜红色素。经过化学修饰后的色素,光稳定性有显著的提高,酸碱稳定性略有提高,热稳定性基本保持不变。

摘  要:
Radish red pigment was chemical modified by etherified molecular modification through orthogonal test,and then the stability was compared with natural pigment.The results showed the optimal conditions were that the ratio of epoxy propane to pigment was 2:5,the mixture was reacted at 0℃ for 35min.The light stability of etherified pigment was improved significantly,while its pH stability was improved slightly,and its stability to heat kept invariant.
