Abstract The effect of high-voltage electrostatic field (HVEF) treatment on the physicochemical properties of chicken fat was studied. After being subjected to HVEF treatment or ordinary heating (control), changes in the peroxide value, acid value, malondialdehyde (MDA) content and color parameters of chicken fat were determined. The results showed that the peroxide value, acid value and MDA level of HVEF treated samples were lower than those of control samples (P < 0.05). All three color parameters showed irregular changes with heating time and methods. To sum up, HVEF could pronouncedly inhibit the oxidation and rancidity of the fat, improve its thermal stability and delay quality deterioration.
