| 摘 要： | 以经过预处理的红甜椒为起始原料,由冷冻干燥法制得红甜椒粉,经过筛选,选取乙酸乙酯为提取溶剂。在此基础上,通过单因素试验考察了温度、提取时间、料液比、超声时间等主要工艺参数对提取效果的影响,并通过正交试验设计对提取工艺条件进行了优化。正交试验结果表明,提取甜椒红色素的最优方案为:提取温度75℃、料液比1∶24、提取时间3.5 h、超声时间30 min,并经3次重复验证试验确认了这一最优工艺条件。

| Abstract: | Red Capsicum annuum powder is prepared by freeze-drying method from the pretreated red Capsicum annuum.Ethyl acetate is selected as the extraction solvent,on this basis,the influence of temperature,extraction time,solid-liquid ratio,ultrasonic time and other main process parameters on the extraction effect is investigated by single factor experiment,and the extraction process conditions are optimized by orthogonal experimental design.The results of orthogonal experiment show that the best extraction scheme of red pigment from Capsicum annuum is:extraction temperature of 75℃,solid-liquid ratio of 1∶24,extraction time of 3.5 h,ultrasonic time of 30 min,which is confirmed by three repeated validation experiments. |
