摘　　要：确定山楂皮渣中果胶超声波辅助提取最佳工艺参数,对所提取的果胶抗氧化性进行研究。以料液比、提取温度、超声波功率、超声波时间作为研究因素,在进行单因素实验的前提下,采用响应面实验设计方法,建立相应的数学模型并开展数据分析。四个研究因素对山楂皮渣中果胶得率的影响由大到小依次为:料液比>超声波功率>超声波时间>提取温度。山楂皮渣中果胶超声波辅助提取最佳工艺参数为:料液比为1∶15、提取温度为74℃、超声波功率为425 W、超声波时间为55 min。在此条件下,山楂皮渣中实际果胶得率为6.154%±0.041%。抗氧化性实验结果显示,提取的山楂皮渣果胶对•OH、•O_(2)^(–)均具有较好的清除效果。响应面优化的山楂皮渣中果胶超声波辅助提取工艺有可行性,提取的山楂皮渣果胶具有一定的抗氧化活性。The purpose of this study was to determine the optimum technological parameters of ultrasonic assisted extraction of pectin from Hawthorn peel residue and study the antioxidant activity of the extracted pectin.Taking the solid-liquid ratio,extraction temperature,ultrasonic power and ultrasonic time as the research factors,on the premise of single factor experiment,the response surface experimental design method was used to establish the corresponding mathematical model and carry out data analysis.The effects of four factors on the yield of pectin in Hawthorn peel residue were as follows:solid-liquid ratio>ultrasonic power>ultrasonic time>extraction temperature.The optimum technological parameters of ultrasonic assisted extraction of pectin from Hawthorn peel residue were as follows:the ratio of solid to liquid 1∶15,the extraction temperature 74℃,the ultrasonic power 425 W,and the ultrasonic time 55 min.Under this condition,the optimal extraction rate of pectin from hawthorn peel residue was 6.154±0.041%.In the antioxidant test of pectin ultrasonic-assisted extraction process in hawthorn peel residue,it was found that the extracted pectin had better scavenging ability on hydroxyl radicals and superoxide anion radicals.The ultrasonic assisted extraction process of pectin from hawthorn peel residue optimized by response surface methodology was feasible,and the extracted pectin from hawthorn peel residue had certain antioxidant activity.
