摘要：葡萄皮渣中含有大量的多酚物质，具有丰富的营养价值和较大的利用价值，但目前对其多酚物质的提取研究较少且多用化学溶剂，提取物应用范围受限。该文使用蒸馏酒替代水和有机溶剂进行提取，并结合超声波辅助法对葡萄皮渣粉末中的多酚进行提取，探讨了蒸馏酒酒精度、料液比、超声时间和超声温度等因素对多酚提取的影响，进一步通过响应面实验确定提取葡萄皮渣粉末中多酚的最佳工艺参数为：蒸馏酒酒精度45%vol、料液比1:23g/mL、超声时间30min、超声温度70℃，在此条件下提取的葡萄皮渣粉末中多酚含量为11.33mg/g，在高效提取葡萄皮渣多酚物质的同时，也大大提高了提取多酚物质的安全性。

Abstract：Grape pomace contains a large number of polyphenols, which have rich nutritional value and utilization value, but currently the extraction of its polyphenols is rarely studied and chemical solvents are mostly used, and the application range of extracts is limited. In this paper, distilled liquor was used for extraction instead of traditional water and organic solvent, and was combined with ultrasonic-assisted method to extract polyphenols from grape pomace powder, the effects of distilled liquor alcohol content, solid-liquid ratio, ultrasonic time and ultrasonic temperature on the extraction of polyphenols were discussed, and the optimal process parameters for extracting grape pomace powder were determined by response surface experiments: distilled liquor alcohol content 45%vol, solid-liquid ratio 1:23 g/mL, ultrasonic time 30 min, ultrasonic temperature 70 ℃. The content of polyphenols in grape pomace powder extracted under these conditions was 11.33 mg/g, which not only efficiently extracted polyphenols from grape pomace, but also greatly improved the safety of polyphenols.
