Tribology: a new tool for the food rheologist’s toolbox

23 June 2014 | By Helen Joyner (Melito), School of Food Science, University of Idaho

Rheology is a powerful tool that can help link food physicochemical properties, structure, and sensory texture to form a cohesive, fundamental understanding of structural and physicochemical contributions to food texture. Yield stresses, fluid flow profiles, and fracture properties of firm solids are relatively easily determined with standard rheometry. However, there…
