Abstract: 【Objective】 The Box-Behnken test design combined with response surface analysis was used to optimize the extraction process of polyphenols in raisins.【Methods】The optimum range of ethanol concentration, material and liquid ratio, extraction time and extraction temperature was determined by single factor test under the condition of ultrasonic assistance. Then, response surface method was adopted to design and measure the extraction rate of total polyphenols and select the optimal conditions.【Results】The optimal conditions of extraction rate was: the ethanol concentration was 54%, material and liquid ratio was 68∶1(mL/g), extraction time was 35 min, extraction temperature was 75℃. The raisin polyphenol content in the validation test was 3.599,2 mg/g with a difference of 0.064,2 mg/g. The dark reaction time was determined to be 40 min. The content of SP522 in raisins was the highest, reaching 3.94 mg/g. The content of non-nuclear purple raisins in the main varieties was the highest, reaching 2.08 mg/g.【Conclusion】The optimized raisin polyphenol extraction process is reasonable and easy to operate
