Summary Physicochemical, cooking quality and sensory characteristics of noodles enriched by extracted flaxseed mucilage were evaluated. Noodles were prepared with replacement wheat flour with different mucilage concentrations and drying at different temperatures. Generally, physicochemical and noodle quality characteristics improved with adding flaxseed mucilage compared to control sample. The correlation between optimum cooking time with mucilage concentrations and drying temperatures established by nonlinear regression. The obtained data of cooking yield, swelling index, cooking loss and nitrogen loss were analysed using the two‐dimension response surface method. The mucilage concentration of 3% and drying temperature ranging between 68.2 and 70 °C were the best condition to prepare the noodle with high cooking quality compared to the control sample. The received scores from sensory evaluation showed that replacement of wheat flour by flaxseed mucilage improved the texture and overall acceptability of prepared noodle.
