    This study focuses on the development of a product based on the partial substitution of conventional flours with unconventional flours such as quinoa (Chenopodium quinoa) and amaranth (Amaranthus caudatus), considering the need to maintain sensory and techno-functional characteristics. Three formulations were developed with the flours and proportions, which were evaluated through physical-chemical analysis, texture, microbiological tests, and glycemic index. A Friedman experimental design was used with a panel of untrained tasters to determine preferences. The results showed that the incorporation and use of quinoa and amaranth improved the nutritional profile of the developed product, in addition to increasing its protein, fiber, and antioxidant content. In contrast, factors such as smell, aroma, and texture significantly influence consumer perception. For this reason, the use of Andean pseudocereals as a partial alternative to wheat in bakery products is viable, significantly promoting options that may be more nutritious and functionally superior to flour. The implementation of pseudocereals opens the possibility of new products for people with diabetes, including food alternatives that comply with the requirements of INEN 3084 for the mixture of dry food products used in baking. Compliance with the microbiological parameters of current regulations demonstrates that the incorporation of pseudocereals does not compromise the safety of the final product, provided that the methodology and preservation of the developed product are respected.
