摘　　要：将高压脉冲电场技术用于提取苹果渣中的果胶。通过单因素试验和正交试验得出了提取苹果渣果胶的最佳工艺参数:电场强度为15 kV/cm、pH值为3、脉冲数为10、料液比为1∶19、温度为62℃,该条件下苹果渣果胶得率最高为14.12%。将该技术与酸提取法、草酸铵法、超声波提取法、微波提取法进行了对比研究,发现高压脉冲电场方法是最为有效的提取果胶的方法。Apple pomace was used as raw material to extract pectin by the high-intensity pulsed electric fields. The optimal processing conditions were acquired by the single-factor experiments and the orthogonal experiment. The most yield rate 14. 12% by pectin was achieved under the following conditions：electric field intensity 15 kV/cm, pH value 3, electric pulse number 10, stuff-liquid ratio 1 ： 19 and temperature 62℃. The comparative extraction tests were performed by the acid extraction method, the ammonium oxalate method, the ultrasonic extraction method, and the microwave extraction method, and it was found that the high-intensity pulsed electric field method is the most effective method to extract pectin from apple pomace.
