A new instrument, the MITEX MK II Bending Tester, is described as a means of measuring the following rheological properties of solid foods: bending moment, curvature, bending rigidity, modulus of elasticity, curvature set and bending moment loss. Equations applicable to bending and results of measurements on samples of celery, carrot, apple and potato are presented. Changes of the modulus of elasticity in relation to the time of exposure of sample strips to the ambient atmosphere, and graphical and mathematical treatment of the data for estimating a total ‘adjusted time’ (age) of a particular sample are discussed.
