摘要
从女贞果实中提取色素,对其进行分离纯化,测定其光谱;并采用正交设计方法对女贞果实色素的稳定性进行试验。结果表明:女贞果实色素在20℃,pH值2,氧化剂浓度为0.01%的情况下稳定性好;同时表明pH值对其稳定性影响很小;温度达到80℃时该色素受到破坏,氧化剂(H2O2)的浓度很低时(0.01%),色素就会受到破坏。
Experiment designed to extract and purify the pigment of Ligustrum lucidum Ait. Fruit and determine action spectrum. Pigment stability were mostly studied by orthogonal design L9 （3^4 ）. The results showed that pigment was more stable when temperature was 20℃, pH was 2 and concentration of H2O2 was 0.01% . The results also demonstrated the slability was little impacted by pH; when temperature reached 80℃ the pigment was damaged, and when oxidant concentration is only 0. 01%, pigment begin to be damaged.
