The objective of this research was to evaluate the effect of the inclusion of cooked Altiplano quinoa flour, tare endosperm and Agave americana leaf flour on the acceptability of cookies, as well as their biochemical parameters in Holtzman rats. Four cookie formulations were developed: the control(I), cookies with partial substitution of wheat flour by cooked Altiplano quinoa flour (II), cookies with (FSEST) and (FIHAA)(III) and cookies including quinoa and fibers (IV). An unstructured scale was used for sensory evaluation in humans. Twenty Holtzman rats were used, distributed in groups of five, for the application of the four formulations. Live weight and food consumption were recorded for 30 days, and feces and urine were collected for the biological test. At the end, glucose, triglyceride, and HDL levels were determined; Subsequently, the animals were sacrificed, liver and intestine samples were extracted and stored for analysis of lipid peroxidation. Non-parametric data were analyzed by the Friedman method, parametric data under a Completely Randomized Design and the comparison of means by Tukey's test. Differences (p<0.05) were found with respect to moisture, crude fiber and TDF in cookies of formulations II, III, IV. The global acceptability and sensory texture showed greater preference (p<0.05) for cookies of formulation II and IV. Higher triglyceride concentration (p<0.05) was found in rats consuming the control diet, which in turn had lower lipid peroxidation protection (p<0.05). BN and VB, glucose, CT, HDL, intestinal parameters were not influenced (p>0.05) by the consumed diets; however, the diet containing cookies flour with cooked Altiplano quinoa presented better digestibility (p<0.05).In conclusion, the consumption of cookies with the aforementioned substitutions improves sensory characteristics in humans and in rats reduces triglyceride levels and oxidative damage of the small intestine and liver.
