In this study, gluten-free pancakes were prepared using rice flour and potato starch at a ratio of 50:50. Due to a lack of gluten networks in these ingredients, the hydrocolloid gums including carboxymethyl cellulose (CMC) at 0.5%, 1%, and 1.5% and hydroxypropyl methylcellulose (HPMC) at 1%, 2%, and 3% were added to improve the quality of the final products. The effects of these hydrocolloid gums on the physicochemical, textural, and sensory properties of the gluten-free pancakes were evaluated. Pancakes prepared with wheat flour were used as a control sample. The results showed that the addition of both gums decreased the hardness and chewiness of the gluten-free pancakes while increasing the springiness and their moisture content. Increasing the concentration of the gums resulted in an L* value (lightness) reduction, which produced a darker crust on the pancakes. Moreover, the gluten-free pancakes containing CMC and HPMC had higher specific volumes than the gluten-free samples made without CMC and HPMC. From a sensory point of view, the samples containing 2%, 3% HPMC and 1% CMC received the highest overall acceptance score. Thus, CMC and HPMC can be used as improvers in gluten-free pancakes.
