摘要
采用超声-微波协同提取技术从核桃壳中提取棕色素,通过单因素试验和正交试验研究了提取时间、料液比、乙醇体积分数及微波功率条件对核桃壳提取的影响。正交试验结果表明:核桃壳最佳提取条件为提取时间8min,料液比1∶5,乙醇体积分数50%,功率400W。
Brown pigment was extracted from walnut shell by means of ultrasonic - microwave technique. And the influences of extraction time, solid - liquid ratio, alcohol concentration and microwave power was determined according to single factor and orthogonal test. Experiment results showed optimum extraction conditions were extraction time 8min, solid - liquid ratio 1：5, alcohol concentration 50%, microwave power 400W.
