| 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。

| Abstract: | 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. |
