Background

Consumers have different extensibility, stiffness, and softness expectations for different bread types. These expectations change as a function of how breads are experienced. For example, breads that are used for children’s sandwich lunches have a different set of firmness expectations than breads for sandwiches in a premium lunch restaurant. While the firmness expectations between breads may differ, in all instances, bread slices should not tear when handled or when spreads are applied. The extensibility of four breads was analyzed with the TA-226 tug fixture. The tug fixture presents a method for pulling apart products like bread without clamps and the inherent problems that clamps present.
