摘要
通过单因素和正交实验研究,对超临界CO2萃取苹果多酚的工艺进行了优化设计。实验结果表明:各因素对苹果多酚得率影响的主次顺序是:萃取时间>萃取压力>萃取温度>料液比;最佳萃取实验工艺条件为:萃取压力35MPa,萃取温度50℃,萃取时间3h,物料粒度40目,夹带剂95%乙醇,料液比(g:mL)1∶2,CO2流速45kg/h,得率为0.1%。
The supercritical CO2 extraction technology of apple polyphenol was optimized by single-factor and orthogonal experiments. Experimental results showed that the successive order of different effect factors on yield of apple polyphenol was extraction time〉extraction pressure〉extraction temperature〉materiel-liquid ratio. The optimal experimental parameters were 35 MPa extraction pressure, 50 ℃ extraction temperature, 3 h extraction time, 40 meshes material granularity, 95 % alcohol entrainer, 1：2 materiel-liquid ratio, 45 kg/h CO2 velocity, the yield of apple polyphenol may get to 0.1%.
