(Universidad Privada Norbert Wiener, 2021-12-09) Gamarra Espinoza, Gino Francesco; Espinoza Rado, Erika Paola
This project had 2 phases. In the First, a survey model was carried out that, through a 5-point hedonic scale corresponding to smell, flavor and texture, is capable of determining which of the 3 formulations presented is the most accepted (F1 = 65%, F2 = 70% F3 = 55%).In the second phase I carry out an analysis of the antioxidant capacity in trolox equivalents to the winning formulation (F2=70%) resulting from the sensory evaluation survey. The sample was evaluated in the Molina total quality laboratories of the Universidad Nacional Agraria La Molina and the points to be evaluated were antioxidant capacity and total anthocyanins. Then the results were as follows: antioxidant capacity was obtained with a measurement of 753,941 ± 33,177 µmol TROLOX eq./g. sample and regarding the total anthocyanin count, the results were 5.79 ± 0.03 in mg./100g. In conclusion, the results obtained from the sensory acceptability test applied to the three blueberry drink formulations determined that formulation No. 2 was the winner, after which the antioxidant capacity and total anthocyanins of the sample were found. No. 2, the results of the first compound far exceed similar formulations (by more than 500%), while in the second compound a concentration greater than 50% is observed. Finally, the study shows us that formulation No. 2 is the most acceptable in a university population and in turn said drink has large quantities of the compounds analyzed during its first hours of production.
