The obtained data from using ohmically heated alternating current (AC) treatment varied voltage from 100-200 volt and varied concentration of NaCl solution from 0.05,0.075, 0.10 and 0.125% on whole fresh guava before extracting guava juice by mechanical extractor was showed that the 100 volt of alternating current (AC) treatment and 0.05% NaCl solution was the best treatment for damaging the whole fresh guava tissue which increased the guava juice from optimum ohmically treatment (100 volt, 0.05% NaCl solution ) were also not significantly different (p
