高導電性液体食品のパルス電界殺菌において品質に対する影響が少ない電極の開発

Green juice is attracting attention as a health food, but since it is a freshly squeezed juice of young barley leaves, it contains soil-derived bacteria. When heat is applied for sterilization, chlorophyll and enzymes in green juice are inactivated, the color deteriorates, and nutrients decrease. Therefore, we are trying to apply pulsed electric field sterilization, but since green juice has high conductivity, a large amount of conductive current flows between the electrodes, which causes temperature rise due to Joule heat and dissipation of the electrodes. Therefore, we have developed a rotary electrode that suppresses the temperature rise of green juice and electrode dissipation caused by Joule heat.
