In this study, different emulsifiers (diacetyl tartaric acid esters of mono and diglycerides [DATEM], sodium stearol‐2‐lactylate [SSL], mono and diglyceride [MG], lecithin [LC] and their combination [DATEM+SSL + MG + LC]) were used in gluten‐free bread formulation containing 30% fermented dough of buckwheat, quinoa, and amaranth flour. The effects of emulsifiers on the quality and staling characteristics of gluten‐free breads were investigated. SSL and the combination of “DATEM + SSL + MG + LC” caused an increase in volume and specific volume and a decrease in hardness values of gluten‐free breads compared to the control. In general, gluten‐free breads containing the SSL and emulsifier combination had lower bread hardness, slower staling rate, and higher sensory scores. In conclusion, SSL and “DATEM + SSL + MG + LC” combination became the most suitable emulsifier applications for improving both technological and sensory quality of gluten‐free breads containing fermented dough of pseudocereals. PRACTICAL APPLICATIONS: Bread has an important place among gluten‐free products, and in this study, the technological, sensory, and staling properties of gluten‐free breads containing 30% fermented dough of buckwheat, quinoa, and amaranth were improved with the use of SSL and “DATEM + SSL + MG + LC” emulsifier combination. In addition to nutritional properties, products with improved technological, sensory, and staling properties were offered to the gluten‐free food market.
