which the electrical conductivity was measured. For
ohmic heating pre-treatment, raw samples of approximately
20 ml were placed into the static ohmic heater
and heated up to 100 8C once and were then collected
for subsequent ohmic heating (OHqOH), for electrical
conductivity determination. The same procedure was
applied for the single ohmic heating treatment (OH),
were the samples were heated only once and electrical
conductivity was measured.
In all cases, the variation coefficient obtained between
the three replicates made for each experiment was below
5%.
