The objective of this work was to study effects of
ohmic heating application on mechanical extraction and
sensory characteristics of guava juice. The AC voltages, 100
150 and 200 volt, were used to treat the whole guava (in 0.05%
NaCl solution providing ions as charge carries) and the yield of
treated guava juice from mechanical extraction was
investigated to determine the optimum of voltage for ohmic
heating process base on the change in voltage. This study
clearly demonstrated that whole treated guava with 100
voltage was the best treatment.
