Rheology offers vocabulary and specific terminology to discuss foods and their textural characteristics
as well as mathematical references to describe these textural characteristics. Fluids could be characterized
by their viscosity and/or by their consistency. Consistency can be defined as a quality of food that is
perceptible to touch or as the resistance to permanent deformation. The term ‘body’ is also used in
reference to consistency. A broader definition of consistency could be the characteristic of a mixture of
fluid and solid foods. Szczesniak referred to consistency as the mouthfeel characteristics of semi-solids or
liquids. Therefore, sensory concepts such as mouthfeel and body could be associated with consistency as
well as more rheological definitions referring to the texture characteristics of the products
