Resumen
Biological structures and behavior of biomaterials are difficult to describe in quantitative terms. In a process such as osmotic dehydration of plant tissues, these complex structures pose a challenging factor in the optimization process and design of equipment. The structure and properties of the tissues affect the mass transfer phenomena occurring in plant tissues during osmotic dehydration. The purpose of this study was to develop a method to classify the mass transfer behavior of different plant materials during osmotic dehydration. The method of classification was based on the description of the material behavior according to easily measurable parameters. These parameters were water loss and solids gain. By fitting an inverse polynomial model to the kinetics data, rates and fluxes of mass transfer were calculated. Two methods of classification were developed based on the rates and fluxes of mass transfer... (A)
