摘要
以玉米皮为原料,利用超声波技术,以乙醇为提取剂从玉米皮中提取玉米黄色素,探讨了料液比、乙醇体积百分数、提取温度和提取时间对玉米黄色素提取率的影响。结果表明:最佳工艺条件为以乙醇作为提取剂,体积分数为60%,玉米皮与乙醇的料液比为1∶15,提取温度为50℃,超声波处理时间为30 min,乙醇提取率可达到6.274%。
The maize yellow pigment was extracted from corn barn through ultrasonic-assisted extraction technology using ethanol as an extracting agent. The effects of parameters such as material-to-liquid ratio, volume fraction of ethanol, extracting temperature and time on the extraction rate of yellow pigment were investigated. The results showed that the extraction rate was up to 6.274% under the optimum extraction condition, e.g. volume percentage of ethanol 60%, corn barn to ethanol ratio of 1：15, extraction temperature 50℃and extraction time of 30 min.
