摘要：In this study; the effects of electroplasmolysis (EP) as a pre-treatment on yield and the effects of microwave (MD) and ohmic heating (OH) by a heat treatment of orange juice quality were investigated.Initially, electroplasmolysis applications were optimized by Response Surface Methodology (RSM). In the second phase of the study; production of orange juice was carried out for each treatment. Trials were done in six application groups with single electrical treatment and combinations of them. Orange juices were produced as 50 ml/sec-900 Watt for microwave heating and 42 V/cm-69 ºC for ohmic heating applications. After production of orange juices; yield and oil content of peel were determined in control and EP groups. After that; pulp content, viscosity, clarifying value, browning index, color values were investigated in all groups. As a result of electroplasmolysis application, more than 8% increase in yield was determined. In addition, EP and electrical heating combinations gave better quality results comparing the conventional thermal heating in orange juice production.
