摘要
运用微波技术辅助,从石榴皮中提取单宁。通过正交实验,考察微波输出功率,皮的粒度,浸提时间,浸提温度等4个因素对提取率的影响。以优化的微波辅助浸提法为实验组,以水提法,乙醇提取法为对照组进行平行实验。结果表明:微波辅助提取法明显优于水提法和乙醇提法。最优的实验条件为:微波输出功率500 W,皮粒径80目,浸提时间30 min,浸提温度60℃。单宁得率可达27.63%。
The use of microwave-assisted technology extract tannin from the pomegranate skin. The four factors of effection extraction rate： microwave power output, partical size, time and temperature were studied with orthogonal experiment. Parallel experiments were carried by the optimal microwave-assistied, compared with water-extraction and ethanol-extraction. The result shows： microwave-assistied is superior to waterextraction and ethanol-extraction. Microwave output is 500 W, partical size is 80 mesh, 30 min, 60 ℃ are the best condition, the yield of tannin is 17.63%.
