The differences in electrical conductivity values are
reflected in the heating curves presented in Fig. 9.
Strawberry topping has considerably lower electrical
conductivity (5% of the electrical conductivity of P1
and 19% of the electrical conductivity of P2) and
a consequently lower heating rate (0.3 8Csy1 comparing
to 1.60 8Csy1 for P2 and 6.22 8Csy1 for the pulp P1)
that would indicate the use of a different ohmic heater
design for this product. This shows the importance of
evaluating the electrical properties of a food intended to
be processed by ohmic heating by clearly demonstrating
the significant differences of electrical conductivity
between the several products tested.
