The total time of the electric treatment (100 volt) by using 0.5,0.75,0.1 and 0.05% NaCl solution were 17,12,9 and 7 minutes respectively. The guava that was electric treated with 100 volt and 0.05% NaCl solution was more time for final temperature to 50ํc so that the guava tissue was damaged for long times caused of a good level of guava juice yield (ุ62.05%) according to Wang and Sastry (2002) from extracting with mechanical extractor which was shown in figure 4 but they were not significantly different (p
