为探讨高压静电场对鸡蛋贮藏保鲜的影响,该试验利用30、60、90 kV/m不同高压静电场分别对鸡蛋进行30和60 min的预处理,然后置于13℃左右的室温条件下贮藏,定期测定鸡蛋的哈夫单位、蛋黄指数、挥发性盐基氮和感官性状的变化等指标,研究高压静电场对其贮藏保鲜效果的影响.试验结果表明:高压静电场处理能很好地保持鸡蛋内部的含水量;有效地降低了哈夫单位、蛋黄指数与挥发性盐基氮的变化速率;贮藏保鲜效果明显好于对照.该试验30 kV/m、60 min剂量和60 kV/m、30 min剂量的处理,保鲜效果最好.

In this paper, in order to discuss the effect of high voltage electrostatic field (HVEF) on storage preservation of eggs, eggs were treated under high voltage electrostatic field at 30, 60 and 90 kV/m, respectively, and the pretreatment time was 30 and 60min, respectively. Then the eggs were stored at 13℃. Different preservation performance indexes like egg white Haugh unit, yolk index, total volatile basic nitrogen (TVBN) and sensory changes were determined regularly. The results showed that moisture content of eggs was maintained, change rates of egg white Haugh unit, yolk index and TVBN were effectively inhibited under HVEF. The preservation effects of eggs under HVEF were better than those of the control group. The best preservation performance is obtained when the dose is at 30 kV/m for 60 min or at 60 kV/m for 30 min.
