An instrumental method for evaluating the ease of extrusion of a decorative cake icing marketed in plastic tubes is demonstrated. The force is measured to pull the tube between two rollers to extrude the contents through the tube nozzle or, by increasing the gap between the rollers, to back extrude the contents within the tube. The maximum force, used as a textural indexy correlated with sensory assessments. The instrumental readings were affected by sample temperature, deformation rate and nozzle size and shape so that these conditions must be standardized. The method has potential use in testing a variety of products marketed in tubes.
