This paper works for research influence on extraction of pectin from apple residue by high intensity pulsed electric fields.The apple residue after pressing is dealed with high intensity pulsed electric fields.The influence regularity of extraction of pectin was investigated.The parameters are electric field intensity,pulse number,pH,stuff and liquid ratio and temperature.The results indicate that field intensity 15kV/cm,pulse number 10,pH 3,and stuff and liquid ratio1:19,temperature 62℃,and the yield of pectin was 14.12%.
