Abstract
ABSTRACTPuncture measurements were made of frankfurter texture using either a pin (straight‐sided shaft) or a disk (narrow shaft) punch. The forces resisting pin punch puncture were compression, tension, and friction, whereas no frictional forces were involved when the disk punch was used. Within a given set of samples, both pin and disk measurements gave the same value (avg. = 413.6 ± 1.9) for the maximum force at the yield points when extrapolated to zero penetration distance. For heterogeneous samples from a previous study, the values ranged from 34.7 to 574.9g. Negative force increments in puncture measurements are explained on the basis of deformation of the gel.
