Cañihua (Chenopodium pallidicaule Aellen) is a little-known native Andean grain of excellent nutritional value, that does not contain gluten. The objective of this study was to develop gluten-free cañihua bread using sourdough and chia seeds. For this purpose, the work was divided into 3 stages: In the first stage, the techno-functional, thermomechanical and physicochemical properties of two varieties of cañihua (cupi and illpa Inia) were first evaluated, then the promising variety was compared with the thermomechanical and rheological characteristics of potato starch, due to its recognized use in gluten-free baked goods and, finally, a standard formulation of gluten-free cañihua bread without added starches with a specific volume of 2.96 cc/g was optimized. The viscoelastic properties of cañihua flour were related to the formation of a continuous protein phase with a predominance of aromatic and sulfur amino acids that, together with dietary fiber and xanthan gum, form a structure comparable to gluten. In the second stage, the physicochemical, techno-functional and thermo-mechanical characteristics of chia flour were first evaluated and then incorporated into the cañihua gluten-free bread formulation with the purpose of improving water retention, allowing to obtain with 7 percent substitution, greater chewiness, but lower specific volume and formation of micro alveoli that provided structure to the system. In the last stage, a sourdough of cañihua flour with Lactobacillus plantarum DSM 20174 was developed and included in the formulation of the previously optimized gluten-free breads to be evaluated for physical, physicochemical and microstructural characteristics, amino acid profile, antioxidant capacity and phenolic compounds. The cañihua bread made with sourdough provides a healthy alternative, with better accessibility of minerals, amino acid composition and good physicochemical and functional characteristics, taking advantage of an ancestral Andean crop resistant to climate change
