Résumé

agar cross-flows diffusion drying interaction mass transfer modelling osmotic dehydration
Agar agar model gel cubes, with initial low sucrose content, were soaked in 40% and 60% sucrose solutions. In both situations, sucrose profiles were obtained by slicing and HPLC analysis. Results provided an experimental validation for the concentrated surface layer assumption and the compartmental model of mass transfer, described in Parts 1 and 2. respectively.
