The concept of high-voltage electrostatic field (HVEF) is characteristic as vector quantity and energy, thereby exerting its effects simultaneously influenced by treatment time and the field strength. In this study, Spanish mackerel were treated by HVEF with four different dosages. The results showed that all the four dosages of HVEF were able to delay the spoilage of Spanish mackerel and extend the storage time. This indicated the feasibility of using HVEF to extend shelf life of Spanish mackerel. In addition, the results also showed that the effects of HVEF on Spanish mackerel varied by dosage, with better preservation effect under higher voltage or longer time. Although the use of HVEF treatment in fresh fruits and vegetables preservation was documented, this is the first report exploring its potential in preserving aquatic products, hence devoid of comprehensive and systematic evaluation. Spanish mackerel were treated with HVEF only at two voltages (30 and 45 kV) and two time points (10 and 20 min) in the experiment; hence it remains to be verified in further studies |
