چکیده

Up to now, in Pulsed Electric Field (PEF) the switching circuit has been used to create pulse train for extracting effective material. These switches are expensive, and complicated in design. In this paper, a new idea has been presented based on omitting the switches. Instead of using switch, narrow plates with the constant voltage were employed which affect on food pieces floating in fluid environment. In this research, some foods have been treated. The PEF strength and pulse numbers were 0.6kV/cm and 1-50pulses, respectively . In these experiments two mentioned methods have been compared in energy consumption and amount of extracted effective material. This paper results indicate that the energy consumption of the new method(7.2J) is less than the traditional PEF system (14.4-138J) in the same results. So, it can be claimed that the fluid system is more effective in extracting materials and improving PEF efficiency.
