Back
ward extrusion tests were conducted with the disc
diameter 45 mm, setting the probe travel distance at
30 mm. Both tests were performed with a test speed
of 5 mm/s, a trigger force of 5 × g, and force in
compression mode. Force-time curves were recorded
at a crosshead speed of 5 mm/s and recording speed
was 5 mm/s to enable evaluation of back extrusion
force (BEF) of the slurry. BEF of slurry may indicate
gelation property potentials of the flour.
