| 摘 要： | 姜黄素是国内外食品行业允许使用的重要天然色素之一,具有很大的市场潜力。本实验应用微波辅助提取技术提取姜黄中的姜黄素,通过单因素实验和响应面优化实验,以对DPPH自由基的清除能力为指标,考察了提取时料液比、处理时间、微波功率、乙醇浓度等影响因素。结果表明,微波提取的最佳工艺参数是:料液比1:43.81、微波功率540W,处理时间30s,溶剂为71.21%乙醇溶液,在此参数下,姜黄素对DPPH自由基的清除率达50.69%。

| Abstract: | Curcumin is one of the important natural pigments used in food industry at home and abroad,showing great market potential.The optimization of extraction technology of curcumin from turmeric by microwave-assisted method was examined by scavenging abilities of DPPH·,using ethanol as extracting solvent based on single factor level test and response surface methodology optimization tests.Results showed that the optimum microwave extraction parameters were:solid-liquid ratio of 1:43.81,microwave power for 540W,microwave treatment time for 30s and solvent 71.21% ethanol solution.Under these conditions,the clearance of DPPH· was 50.69%. |
