Ohmic Heating Behaviour and Electrical Conductivity of Tomato Paste
The ohmic heating rate of a food is highly influenced by its electrical conductivity (σ). In this study, tomato was ohmically heated by using five different voltage gradients (6–14 V/cm). Measurements were made from 26 to 96°C and showed a linear increase in σ values with increasing temperature. The voltage gradient was statistically significant on the heating time (P < 0.05). The ohmic heating...

investigation of voltage gradient and electrode type effects on processing time, energy consumption and product quality in production of tomato paste by ohmic heating
introduction thermal processing has a huge impact on the textural attribute of the final food product and texture is a major factor contributing the overall quality of food. ohmic heating is an advanced thermal processing method in which heat is internally generated within foods by passing an alternating electric current through them. ohmic heating can volumetrically heat the entire mass of a f...
