The influence of carboxymethyl cellulose and hydroxypropyl methylcellulose on physicochemical, texture, and sensory characteristics of gluten‐free pancake

Abstract

AbstractIn 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.
