【摘要】 以橘皮为试材,采用超声波辅助提取工艺对橘皮中叶黄素进行了研究。结果表明:橘皮叶黄素在可见光范围内的最大吸收峰为448nm,L9（34）正交实验确定了影响叶黄素提取效果的最主要因素是提取温度,并得出橘皮叶黄素提取的最佳工艺条件是丙酮浓度60%、料液比1∶15kg·L^-1、提取时间60min、提取温度60℃。同时研究光照强度、pH、金属离子、温度、氧化剂和还原剂对叶黄素稳定性的影响。强光、较低pH、不同金属离子、高温、维生素C均对橘皮叶黄素有一定的降解作用。更多还原

【Abstract】 Taking orange peel as test material,the extraction and quality of lutein from orange peel was studied.The results showed that the maximum wavelength of the lutein from orange peel was 448nm;the results of L9（34）orthogonal test showed that the most important factor was the extraction temperature,the optimum condition of the lutein from orange peel was determined as the acetone concentration 60%,the solid-liquid ratio 1∶15kg·L^-1,the extraction time 60 minutes,the extraction temperature 60℃.The high-light,low pH value,different metal ion,high temperature,vitamin C had more effection on the degradation of lutein from orange peel.更多还原
