McManuis suggests measuring bread to 25% deformation with a flat-ended 10 cm2 probe at a speed between .17 and .83 mm/second. He goes on to caution against 'inadvertently stacking' slices of bread on top of another, and his table down plays the necessity of a trigger force. The AACC (74-09) Standard Method for bread freshness (available in our software's help menu) calls for using two 12.5 mm thick slices of bread (or one 25 mm thick slice) with a 36mm diameter cylinder (10.2 cm2 ) probe with a radius edge (so as to not cut the bread) at a speed of 1.67 mm/second (more than twice as fast as McManuis' upper speed range). While the standard method calls for the force to be captured at 25% strain, the method actually calls for the probe to travel 40% strain. The original method was actually written for InstronTM machines, and the method had to overcome the difficulty they had in triggering at the surface of the product and the strip chart recorders which captured Instron Corp data then (1986). With modern texture analyzers the trigger force allows operators control over an important variable which cannot be controlled with Instrons, perhaps why he down plays its importance. Even mechanically sliced bread is not perfectly flat and the captured force at the 25% strain distance should be calculated from a repeatable determination of the true surface of the bread. Test results which were obtained following McManuis's recommended test method (primarily the wrong speed) would not be comparable with results which followed the actual AACC method.
