It's well known that the structural characteristics of food materials influence their mass transfer, especially their water transfer properties during such processes as drying, hydration, and storage. In porous cereal-based products, for example, effective water diffusivity is highly affected by the volume fraction and distribution of both solid and gas phases, while in dense food materials, such as fat-based or other edible coatings, it depends on factors that affect the "e;tightness"e; of the molecular structure (e.g., free volume, cohesive energy density, crystallinity). This Brief will review the impact of food structure on moisture transfer. A multi-scale analysis of food structure will include a look at molecular structure (e.g., free volume, crystallinity), nanostructure, microstructure (e.g., porous food), and macrostructure (e.g., bilayer structure). For each structural analysis, a focus on the mathematical modelling of the relationship between structural properties and moisture transfer properties will be performed.
