Rheology as a design tool for novel food concepts

2 September 2014 | By Leonard M. C. Sagis and Elke Scholten, Physics and Physical Chemistry of Food, Wageningen University

The rheological properties of food products are very important in the production, preparation, and consumption of food. Rheological measurements are therefore a highly useful tool in the design of novel food concepts. Here we discuss the use of rheological techniques to develop and characterise pasta and noodle products, with high…

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…
