Chewiness of gluten-free pasta could be related to the elastic
force of the protein matrix in the sample (Sozer et al., 2007); the
highest chewiness valuewas 39.9(0.8) and corresponded to W1EP3
(highest level of proteins and lowest level of water). Although a
polynomial model did not adequately fit experimental data of
chewiness, the analysis of variance showed that there was a significant
EPxW interaction, at EP ¼ þ1 chewiness was inversely
proportional to water content in the dough while the opposite effect
was found at EP¼1. Control wheat flour dough presented an
average chewiness of 26.8(1.0), whichwas in the range of the values
of the GF pasta evaluated.
