Normally, the method that using to production was Ohmic heating, which is a generating heat from inside food sample. A result of the discharge current flowing through to food and the resistance to flow of electric current in food until the heat at high temperature. A kind of food is appropriately for ohmic heating should be high conductivity and tend to more when high temperature. Ohmic heating was used exist for heating, blanching, evaporation, fermentation and extraction (FDA, 2001).
