因为静电场是一个具有矢量及能量特征的概念，故而产生的作用效果同时受时间与场强2 个条件影响。经过试验发现，通过4 组不同剂量的高压静电场对鲅鱼的处理，结果表明，4 组不同剂量的高压静电场对鲅鱼的保鲜效果均好于对照组，表明利用高压静电场延长鲅鱼的货架期是可行的。另外，试验结果还表明不同剂量的高压静电场保鲜鲅鱼的效果不同，采用较高的电压和处理时间，对鲅鱼的保鲜效果更好。虽然静电场保鲜果蔬的研究在国内外早有报道，但本试验研究高压静电场在鲅鱼保鲜方面的影响是首次的探索性试验，在国内外尚无报道，所以缺乏全面系统的判断。并且在上述试验结果中，其电压仅采用30和45 kV 2 种电压与10和20 min 2 种时间，所以，还有待于进一步试验研究，才能得到证实。 Highvoltage electrostatic field (HVEF) is a concept of vector and energy characteristics, its effect on samples are affected by treating time and treating voltage. In the experiments, Spanish mackerel were treated by HVEF in 4 groups of different dose, the experiments results has shown all 4 groups of different dose of HVEF can delays the spoilage of Spanish mackerel and extend storage time, which showed that using HVEF to extend shelf life of Spanish mackerel is feasible. In addition, the experiment results also show that the Effect degree of HVEF on Spanish mackerel is different by different dose, Spanish mackerel were treated by higher voltage or longer time, the preservation effect is better. Although using HVEF treated fresh fruits and vegetables have been reported, the usefulness of HVEF in preserving aquatic products freshness was explored for the first time. so it is lack of comprehensive and systematic judgment. At same time, in the experiment, Spanish mackerel were treated by HVEF only by 30 and 45 kV, and the treated time is only 10, and 20 min, therefore, it need be confirmed by further experiment. |

| 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 |
