Evaluation of Non-Fermented Dough from Wheat/Barley/Hemp Composites

Abstract Basic wheat-barley flour premixes (70 : 30 and 50 : 50) were enhanced by 5 and 10% of dehulled and hulled hemp seeds wholemeal or by 2 types of hemp fine flour. Barley flour (BF) decreased both protein content and quality by approximately 1.5 and 50%, respectively. In blends, hemp fine flour containing recovered protein level back. BF lowered amylases activity by about 20–25% in maximum; hemp products had no significant effect. Farinograph water absorption was magnified by additions of both alternative flours. Considerable shortening of dough stability and decrease of resistance against over-mixing occurred for all flour tri-composites. Extensigraph dough elasticity increased and extensibility diminished. After dough resting taking 30 min, extensigraph energy of the control sample fell from 141 cm2 to a half as barley flour portion increased. In cereal composites, hemp products demonstrated reversal tendencies. BF lowered water suspension viscosity, but hemp wholemeal H4 and especially fine hemp flour H7 caused a recovery of amylograph maxima to level comparable with wheat control. Correlation analysis confirmed analytical and rheological data agreement – the extensigraph elasticity or energy could be predicted according to the Zeleny value, or the amylograph maximum according to the Falling Number (r = 0.79, 0.90, and 0.65, respectively; P = 99.9%).
