Besides, the loss which might emerge in soluble proteins and other nutritional elements leaking from solid phase,
the consumed high energy and plenty of infiltration water are accepted to be disadvantages in traditional thawing.
Working principle of ohmic heating system is based on passing electric potential through the food which has
resistance at a certain level. In this process, the potential passes through the food material rapidly because the
potential is dissipated into the food equally and the heat emerges as a result of resistance to the potential. As the
potential is dissipated into the food equally, less repetition of operation is needed to obtain the same temperature in
comparison to traditional methods and thawed food has higher quality. It is thought that this method can be
employed as an alternative method in meat thawing. As a matter of fact, Li and Sun (2002) state that ohmic heating
system can be used in order to thaw frozen food, so it is possible to thaw frozen tuna fish from -30
C to 30
C in a very
short time. In this study, the research was done on use of ohmic heating system thawing operations, along with
traditional thawing methods, and its effects on quality.
