Conditioned wheat kernels and their doughs, from soft and hard wheat classes were evaluated for total work (Wt), elastic work (We) and plastic work (Wp). RESULTS: Soft wheat kernels showed lower Wethan Wp, while the hard wheat kernels had a Wethat was higher than Wp. Regarding dough visco-elasticity, cultivars from soft and hard wheat showed higher Wpthan We. The degree of elasticity (DE%) of the conditioned wheat kernel related to its dough decreased ∼46% in both wheat classes. The Wt, Weand Wpfrom the soft wheat kernel and dough correlated with physico-chemical and farinographic flour tests. The Wt, Wpand the maximum compression force (Fmax) of the dough from hard wheat class presented highly significant negative correlations with wet gluten. CONCLUSION: The visco-elasticity parameters from compression test presented significant differences among conditioned wheat classes and their doughs. © 2016 Society of Chemical Industry.
