摘要
目的:优化超声-微波协同提取橄榄多酚的工艺条件,为工业化生产中提取橄榄多酚提供参考。方法:在单因素实验的基础上,采用响应面法优化超声-微波协同提取橄榄多酚的提取工艺。结果:橄榄多酚最佳提取工艺为:微波功率为550 W,微波提取时间为4.4 min,超声功率为330 W,乙醇浓度为62%,此条件下的橄榄多酚实际得率为6.33%,接近于模型预测值6.35%。结论:该工艺简便、快速、得率高,为工业化应用提供了精确有效的参考标准,为广泛开发利用橄榄资源提供了良好的参考价值。
Objective： The technology for ultrasonic- microwave synergistic extracting polyphenols from Canarium album was optimized,which can provide certain references for actual production. Methods： On the basis of single factor experiments,the optimum conditions for the extraction of polyphenol was obtained by response surface methodology.Results： The optimum conditions of extracting polyphenol from Canarium album were as follows：microwave power 550 W,microwave extraction time 4.4 min,ultrasonic power 330 W,ethanol concentration 62%.Under these conditions,the polyphenol yield was 6.33%,which was close to the model predictive value of 6.35%.Conclusion： the optimum process was simple and rapid,which had good yield.Furthermore,this study offered not only an accurate and effective reference standard for industrial applications,but also a good reference value for widely exploitation and utilization of Canarium album resource.
