Ohmic Heating Technology - A Review

Ohmic heating is a novel technology for food processing. This review paper summarizes there search progress and application in Ohmic heating technology used in food processing. Ohmic heating is an electrical resistance heating method for the heat treatment of food products. When electric current passes through the food, the food heats up because of its internal electrical resistance. In this process heating rate depends upon the electrical conductivity and field strength. By this method a product under goes a minimum structural damage, retain its nutritional value. This technique gives excellent processed quality products in minimum operating time.
