摘要
介绍了用95%乙醇作溶剂,从山楂中提取红色素的工艺条件和方法。试验结果表明:水浴加热保持50℃左右,萃取时间为40～50min,萃取效果最好。将萃取液在50～60kPa条件下减压蒸馏,分离色素并回收溶剂。
To describe the extraction process conditions and methods of red pigment from hawthorn with 95% ethanol as solvent.The test results showed that water bath heating was kept about 50 ℃,extraction time was 40 to 50 min,extraction effect was the best.To separate the pigments and the recover solvent by vacuum distillation of the liquid in 50~60 kPa.
