Abstract
In order to produce dough with a lower gluten content, more enriched with the rice components and satisfactory rheological properties, the rheological properties, energetic value and cake baking properties of wheat and white or brown rice flour in shares from 3 to 30% (w/w) were investigated in this paper. The water absorption in wheat-rice flour mixtures was less and decreased to 53.5 % and 54.0 % along with the increase of the white and the brown rice flour share, respectively, than in wheat flour, where it was 58.8%, In the dough made from rice flour a gluten network had thinner filaments, about 2 and 1 ?m in width for white and brown rice flour, respectively, compared to those in the dough from wheat flour only, where it was about 7 ?m. The dough from rice flour had almost twice as higher gelatinization maximum as the gelatinization maximum of the wheat flour only. The energetic values of the dough from rice flour were smaller than the energetic value of the wheat flour, for only 1.32%. Based on Cluster analysis, the white or brown rice flour share of 20% was pointed out.
