The Grain Research Laboratory compression tester, a versatile instrument for the measurement of the textural properties of bread crumb, is described. A plunger attached to a force transducer is moved vertically by a variable-speed motor-driven cam that provides precise, repetitive compression of foods either to constant deformation or to constant force in conjunction with a comparator. To demonstrate the potential of the instrument, textural properties including firmness, stress relaxation, cohesiveness, and stickiness were measured in bread crumbs from loaves stored for various periods of time.
