| 摘 要： | 研究从石榴皮中微波辅助提取多酚的工艺.采用单因素试验及正交试验,考察不同条件下石榴皮多酚提取率.结果表明,提取溶剂乙醇体积分数、微波功率、提取时间得料液比均对石榴皮多酚提取率有显著影响；石榴皮多酚的最佳提取条件为50％(体积分数)乙醇作溶剂,微波功率300W,提取时间120s,料液比1∶35(m∶V).该条件下提取石榴皮多酚,提取率可达21.41％.

| Abstract: | The microwave assisted extraction of polyphenol from pomegranate peel was studied in the paper.Single-factor and orthogonal experiments were used to study the extraction rate of pomegranate polyphenols in different conditions.The Single-factor experiments showed that extraction rate of polyphenol was influenced significantly by extraction solvent volume fraction of ethanol,microwave power,extraction time,and solid-liquid ratio.The optimal extraction process identified by orthogonal experiments was as follow... |
