Estimation model for electrical conductivity of red grape juice

Rittichai Assawarachan

Abstract


The equations for predicting the electrical conductivities of red grape juice at different concentrations have been evaluated in this study.  Three samples of red grape juice having concentrations of 10.5, 12.5 and 14.5°Brix were ohmically heated by applying three different voltage gradients (10, 12 and 15 V/cm) in the temperature range of 25-80

Keywords
