| Objective To obtain the optimum extraction condition of polyphenols contained in apple by microwave-assisted method. Methods Polyphenols in apple were extracted by microwave-assisted method. The effect of power, extraction time, solid-liquid ratio and ethanol concentration on the extraction rate of polyphenols was discussed under the influence of microwave. Based on single factor experiments, the optimum extraction was determined by response surface analysis. Results The yield of apple polyphenols was affected by various factors in a descending order as: microwave power, ethanol concentration, microwave extraction time and solid-liquid ratio. The optimum extraction condition was as follow: ethanol concentration 50%, microwave power 640 W, extraction time of 70 s, solid-liquid ratio 1:14 (m:V), and the extraction rate of polyphenols was up to 9.92 mg/g. Conclusion From the experimental results, microwave-assisted method is fast and effective, safe and convenient to extract polyphenols contained in apple and can obtain extraction rate better. |
