In order to improve the thawing qualities of aquatic products, shrimps (Penaeus vannamei) as a representative of aquatic products, were thawed with high voltage electric field (HVEF) at different voltages. It was compared with an air-thawed control on the basis of thawing time and the post-thawing quality of the shrimps. The results showed that HVEF can reduce the thawing time of shrimps significantly. Compared with air-thawed control, the thawed shrimps under HVEF had better post-thawing qualities such as lower thawing loss, lower total bacteria count and lower total volatile basic nitrogen (TVB-N). HVEF thawing has advantages. This suggests an application potential for HVEF treatment in the thawing and storage of frozen aquatic products.

In order to improve the thawing qualities of fish, a thawing process of high voltage electrostatic field (HVEF) was studied. It was compared with nature thawing on the basis of thawing rate and the fish’s qualities index such as pH, thawing loss, cooking loss and total volatile basic nitrogen (TVB-N). The results showed that the high voltage electrostatic field can improve the thawing rate of fish significantly. Compared with nature thawing, the thawed fish under t HVEF had better qualities such as lower thawing loss and total volatile basic nitrogen (TVB-N). HVEF thawing has advantages, which can be used as a substitute method.

Abstract-In order to further explore the biological effects of electromagnetic treatment technology on crop seeds, in this paper, the mung bean seeds are treated by electric and magnetic field with different dose, then mungbean seeds are cultivated in water, a control group is set. By observing the change of the circumstance of the germination percentage, the best intensity of the electric field and magnetic field are selected, so that this kind of technology can be well used in agriculture. The experiment shows that the germination percentage of seeds treated by electric field and magnetic field can be improved, and the seeds treated by electric field with 25kV and magnetic field with 0.6T is superior to other groups on the germinate rate.
