Abstract: By high intensity pulsed electric fields(HPEF) treatment and with ratio of insoluble matters in acetone as measurable index, the optimum parameters of HPEF for extraction of yolk lecithin were: the pulse number 35, the electric field strength 20 kV and the concentration of additives 18 ml/g.

Key words: lecithin, HPEF, extraction rate
