摘　　要：采用超声波辅助提取法提取柚子皮中的天然色素,通过响应面法优化试验,确定柚子皮中天然色素的最佳提取条件,并对其稳定性进行研究。结果表明:柚子皮色素提取的最佳条件为乙醇体积分数63%、提取温度63℃、提取时间22 min。稳定性试验表明,柚子皮色素在低温、避光的情况下较为稳定,还原剂与甜味剂对其稳定性影响较为明显,Fe~(2+)、Cu~(2+)对柚子皮色素细胞具有破坏作用,抗坏血酸、柠檬酸、山梨酸钾和苯甲酸钠对色素稳定性的影响较小。The ultrasonic assisted extraction method was used to extract natural pigments from grapefruit peel.The optimal extraction conditions for natural pigments in grapefruit peel were determined through response surface optimizating experiments,and their stability was studied.The results showed that the optimal conditions for extracting grapefruit peel pigment were as follows:ethanol volume fraction 63%,extraction temperature 63 C,and extraction time 22 min.Stability tests showed that grapefruit peel pig-ments were relatively stable under low temperature and dark conditions.Reducing agents and sweeteners had a significant impact on their stability.Fe2 and Cu²+had destructive effects on grapefruit peel pig-ment cells,while ascorbic acid,citric acid,potassium sorbate,and sodium benzoate had a relatively small impact on pigment stability.
