The objective of this work was to study changes in technological characteristics and sensory properties of gluten-free muffins when using chickpea flour (CF) alone and/or with partial CF replacement by corn starch (CS). The effect of partial whole egg replacement by egg white (EW) was also investigated. Four different CF:CS ratios (100:0, 75:25, 50:50, and 25:75) were used in formulations with and without incorporated EW, and compared with wheat flour (WF) muffins (0:0). Muffins prepared from CF alone had lower hardness, springiness, cohesiveness, chewiness, and resilience than control ones. However, reducing protein content by CS addition significantly increased texture profile analysis parameters of muffin crumb. Muffins prepared with 25:75 ratio had a structure with springiness similar to muffins made with WF but were too hard. Reducing whole egg content by partial replacement with EW also significantly increased muffin hardness. Flash profile performed by consumers showed a clear discrimination of muffins according to CF:CS ratio. Muffins containing both CF and CS at 50:50 ratio had the same high overall acceptability and purchase intention as gluten ones. Gluten-free CF-based muffins of satisfactory quality can be manufactured by CS incorporation, either with or without EW.
