    An efficacious mixture made from ancestral seeds: quinoa, amaranth, sacha inchi and chia has optimal protein and lipid profile. In addition, it was demonstrated through the analyzes in the RVA the obtaining of a homogeneous matrix with water retention capacity, gel resistance and film formation, which incorporates polyunsaturated fatty acids and precooked flours. By hydrolysis the protein in the supplement, a protein concentrate yield of 72 percent was obtained at a pH of 4.0. In addition, by means of the electrophoresis technique an immunoprotein band with a molecular weight of 30 KDa was identified, highlighting the globulin fraction 11S called chenopodin, known as an emerging allergen resistant to gastroduodenal digestion. Through the digestion process of the starch in the supplement, it was possible to verify the efficacy of the formulated matrix, obtaining 85.39 percent of starch slowly hydrolyzed to maltoses, reaching its maximum digestibility after one hour. When carrying out the characterization of the supplement, we can conclude that it does meet the nutritional requirements for adolescents according to the recommended daily intake recommended by the Food and Agriculture Organization of the United Nations. In addition, the incorporation of essential fatty acids in a microencapsulation to the pulverized precooked flours allows the matrix to be effective due to its bioaccessibility, absorption and subsequent transformation. The supplement obtained from ancestral seeds considered as golden grains has a protein profile suitable for adolescents and a balanced lipid profile. For its sensory acceptability, it was determined that the best treatment chosen for the panelists was the strawberry flavor sweetened with sucralose. The development of the research will strengthen food sovereignty, promoting the production of underdeveloped foods, contributing to the circular economy, reducing water consumption and promoting agricultural activity.
