An improved adhesion testing apparatus (20) for the accurate, quantitative measurement of adhesion of coherent flowable materials such as doughs is provided which includes an extrusion-type sample holding device (42) together with a shiftable probe (38). The device (42) includes a base (46) threadably interconnected with a top (48), the latter supporting an extrusion screen (50). In use, a dough sample placed within the base (46) is extruded through the screen (50) in order to present a test portion (92) above the screen (50); the plunger (38) is then lowered into contact with the portion (92), and rapidly withdrawn. The force required to separate the plunger (38) from the test portion (92) is recorded as a measure of adhesion. Provision of the screen (50) essentially eliminates the potentially interferring factor of dough flow in the measurement of adhesion.
