Abstract

Diffusion and mass transfer are ubiquitous operations in food processing. The application of electric fields can influence the mass transfer properties of foods. A small scale processing unit was used in the development of a method that would allow real-time measurement of diffusion of dyes into gel samples (at a range of temperatures and electric field strengths). The depth of penetration and localisation of infused material can be visualised and measured using image analysis methods.
