Alternating Current (AC) treatment of food material,
ohmic heating, is used for rapid thawing of food.Ohmic heating process is used for pasteurization and
sterilization of food for preservation and microbial
inactivation. Ohmic heating can be used as an
blanching system for food. The electrical current
through a food that serves as an electrical resistance.
Recently there has been research on new application of this
technique to food processing. For example, ohmically heated
can be used for enhancing expression of juice from plant
tissue.
