In this study, we are aimed for application of shock wave to food processing. An explosive is usually used as an energy source to generate shock wave, but there are various obstacles for use of an explosive. So, we introduce shock wave generated by the metal wire explosion using high voltage discharge. Almost foods after processing by shock wave are shown the effects of softening and improvement of osmosis. In this time, we measured pressure generated by the each devices and the value of hardness and pH of processed food to evaluate the device. As a result, when we compared shock pressure by an explosive with that of high voltage discharge, these values approximately at the same level were measured. From comparison of the result that processed food in each device, hardness and pH together are not shown big difference. Thus, it was shown that this device with the metal wire explosion had ability for enough processing.

High Voltage Discharge

The application of high-voltage discharge plasma for water pollutant decomposition and the synthesis of nanoparticles under a high-pressure argon gas environment (~4 MPa) was demonstrated. The experiments were carried out in a batch-type system at room temperature with a pulsed DC power supply (15.4 to 18.6 kV) as a discharge plasma source. The results showed that the electrode materials, the pulsed repetition rates, the applied number of pulses, and the applied voltages had a significant effect on the degradation reactions of organic compounds. Furthermore, carbon solid materials from glycine decomposition were generated during the high-voltage discharge plasma treatment under high-pressure conditions, while Raman spectra and the HRTEM images indicated that titanium dioxide with a brookite structure and titanium carbide nanoparticles were also formed under these conditions. It was concluded that this process is applicable in practice and may lead to advanced organic compound decomposition and metal-based nanoparticle synthesis technologies.
