Effect of inulin, guar gum and pectin blend on dough rheology

Fibres and hydrocolloids improve bread nutritional value, shelf-life, and/or frozen storage stability. In this work we investigated the effect of pectin, guar gum and inulin addition on wheat dough water binding and viscoelastic properties by using a response surface methodology. Dough rheological parameters were determined by farinograph, extensograph and microviscoamylograph (Brabender, Germany). Pectin (0.2-1%), guar gum (0.1-0.5%) and inulin (0.6-3%, w/w on flour basis) were added to white wheat dough according to the central composite experimental plan. The results showed that the guar gum was the most effective blend component to decrease dough softening and to raise paste peak viscosity. Pectin significantly negatively affected dough energy. Inulin slightly decreased water absorption and paste viscosity but improved dough energy. The best results in terms of increased water absorption, dough energy and paste viscosity were obtained by adding inulin about 1.3%, pectin 0.3% and guar 0.5%. Inulin in combination with guar and especially pectin could be used in production of fibre enriched breads.
