Abstract: This study investigates the effect of high-voltage electrostatic field (HVEF) salting on the quality of salt-reduced Yi Ye Cheng golden pomfret. Results showed that the salt content increased with the voltage (P<0.05). The cooking losses of the HVEF-treated groups were significantly lower than those of commercially available products (P<0.05). The 3.0 kV group showed the highest hardness and chewiness. HVEF treatment increased the varieties and contents of volatile flavor substances, with the varieties and contents of aldehydes, ketones, and alcohols being highest at 3.5 kV. No ketones with OAV>1 were detected in the commercially available products, but all the HVEF-treated groups contained 2,3-octanedione. Lipid and protein oxidation increased with the voltage (P<0.05), which may account for the changes in water retention, texture and flavor. Therefore, moderate HVEF treatment had a positive effect on the quality. This study provides theoretical guidance for curing and improving the quality of salt-reduced fish products.
