The aim of this work was to determine the optimum mixture of isinglass, chia and quinoa that would allow obtaining a jelly with the best physicochemical properties and greater sensory acceptability. Ten jelly mixtures (G1-G10) based on chia, quinoa and isinglass were prepared, with concentrations between 3.00-5.75%, 0.25-2.08% and 400-6.75%, respectively. These jellies were analyzed by penetration and compression tests. Of these jellies, stand out mixtures G3 and G10, with concentration of isinglass, chia and quinoa of 6.75%, 3.00%, and 0.25%; and 5.83%, 0.71%, and 3.46% respectively, as the mixtures with the best texture profiles (greater breaking strength, firmness and hardness). In addition, the G3 mixture showed the lowest percentages of syneresis at 4 and 18 days, with values of 89.70% and 89.54%, respectively. Moreover, an ideal mixture, called G11, was obtained by response surface analysis, whose contents of isinglass, chia and quinoa were 5.76%, 3.31% and 0.84%, respectively. Based on the results obtained, G3, G10 and G11 gels were subjected to sensory tests by a trained panel, general public acceptability survey, children aged 4-6 years, and children aged 9-11 years of public and private schools. The trained panel assigned a higher score for the G3 mixture in the cutting resistance and firmness parameters, while the G10 mixture showed a higher score in the friability, flavor and sweetness parameters. However, this sensory panel did not report differences in the overall score of the tested mixtures, as did most of the children's panelists, who did not perceive differences in the tested mixtures. Finally, based on the obtained results, the G3 mixture showed the greater physicochemical stability and the better texturometric profile (breaking strength, firmness and hardness), and greater sensory acceptability (cut resistance and firmness). On the other hand, the G10 mixture showed the better texturometric profile in terms of elasticity, and greater sensory acceptability regarding friability, flavor and sweetness.
