    The research project arose from the identification of community needs through the system of linkage with society, applied in the Association of Agricultural Entrepreneurs Virgen del Tránsito of the Parish of Guaytacama; this organization is dedicated to the production of chocho variety INIAP- 450 Andino, raw material that has been proposed alternatives of food transformation as the preparation of precooked dough for pizza through the partial substitution of wheat flour by chocho flour. The objective of the research was to evaluate the physicochemical and sensory characteristics of precooked pizza doughs based on the partial substitution of wheat flour by chocho flour. The experimental design was applied in a factorial arrangement A*B+2 with two replications and for the sensory analysis a (DBCA). The main results of the research were that the proximal characterization of the raw material revealed that chocho flour has 57.20% protein; In the physicochemical analysis of the precooked pizza doughs, the best treatment was identified with 31.7% moisture, 20.5% protein content, 2.03% ash, and the best concentration for substitution was t6 (60% chocho flour + 40% wheat flour + oil), parameters established by the INEN 2945 Standard in the sensory analysis applied to 20 tasters, which evaluated organoleptic characteristics such as: flavor, texture, odor, color, fragility, chewiness, hardness, elasticity, obtaining that treatment t_1 ( 20 % chocho flour + 80 % wheat flour + butter), presents better characteristics. For the microbiological analysis of the two best treatments obtained, mold and yeasts were evaluated; functional mechanical tests were carried out, such as: cohesiveness, elasticity, firmness and chewiness in the final product; the nutritional analysis reports a low percentage of fat, higher protein content.
