Cylindrical snacks are described by crispness and fracturability,
while ring-shaped snacks are described by adhesiveness and hardness,
and chewiness is important to describe shell-shaped and pelleted
snacks. The instrumental forces derived from the cut tests
correlate strongly with sensory attributes, and that hardness and
adhesiveness present correlations with the Warner–Bratzler test
using a ‘‘V’’ shape probe, while fracturability and chewiness correlate
with the Warner–Bratzler test using a guillotine. The fairly
strong good correlations enable application of these instrumental
tests as an indicator of the sensory texture of extruded snacks,
which facilitates comparisons among scientific works and allows
to industries produce extruded snacks with desirable sensory texture
characteristics.
