Microwave combined drying of red beetroot puree pretreated by ohmic heating

Abstract

Ohmic heating is an advanced thermal food processing technique where heat is internally generated in a sample using the electric current. This provides rapid and uniform heating in the intire volume of the sample. This novel technique based on the electric field is resulting in less thermal damage in food. Ohmic heating has immense potential for achieving rapid and uniform heating in foods, providing microbiologically safe and high quality foods.
