    Determinación de componentes fenólicos y antioxidantes en la harina de chocho (Lupinus mutabilis sweet) y melloco blanco (Ullucus tuberosus)

    Desnutrition has increased in recent years within the country. Mainly affecting children and older adults. The disinformation about the qualities and properties of daily Andean crops such as chocho and melloco blanco is one of the main reasons why they arewasted and, therefore, contributes to the increase of malnutrition in the country. The present research focuses on the determination of phenolic components present in chocho and melloco blanco by means of optical techniques such as HPLC coupled to a UV-VIS spectrophotometer, through which the presence of components such as gallic acid has been determined in both samples. In addition, in the case of melloco blanco, it was possible to determine the presence of flavonoids such as rutin, which has anti-inflammatory properties. And for the chocho, it was possible to determine the presence of p-coumaric acid. Subsequently, the antioxidant capacity was determined by the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. With this technique it was determined that chocho ́s and mellocoblanco's flour have a inhibition percentage of DPPH radicals of 12.56 and 86.96 percent respectively. Finally, the data obtained were related to the importance of the inclusion of these crops in the formulation of functional foods so that they can be included in the consumer's diet.
