title: Mixing, tensile and pasting properties of wheat flour mixed with raw and enzyme treated rice bran.
abstract: Rice bran is a potential fiber and minerals source for nutrients enhancement of cereals food. For evaluation of rice bran applied in bread making, mixing properties, tensile and pasting properties of wheat flour dough with raw (RB) or enzymes treated rice bran (ERB) were investigated. Farinogram with two peaks, which was observed in the dough with 40 % ERB, was reported. For mixing properties, addition of RB and ERB significantly decreased water absorption and stability of wheat dough. Dough development time of mixed flour with ERB was longer than that with RB. Water absorption, stability time of the dough and farinograph quality number is negatively correlated with addition of RB and ERB. The alveograph tests indicated that extensibility of dough decreased remarkably with increased RB or ERB addition and RB had more negative effects than that of the ERB. Results of pasting behaviors predicted that addition of RB or ERB, could slow down starch retrogradation and delay bread staling. In general, wheat flour mixed with 20 % RB or ERB was fit for bread making and the later expects better sensory and nutritional values.
