Resumen
En los últimos años se ha suscitado creciente interés científico por los metabolitos secundarios
presentes tanto en la uva como el vino en especial por los compuestos polifenoles, potenciado
por el hallazgo de sus propiedades antioxidantes y su papel que esta desempeña en la cura de
enfermedades degenerativas, el cáncer, la diabetes, enfermedades cardiovasculares y del sistema
nervioso, además de procesos inflamatorios, el objetivo del presente estudio fue determinar el
contenido de compuestos polifenoles y la actividad antioxidantes de los vinos producidos
artesanalmente en la ciudad de Ica, se tomaron 15 muestras de vinos de igual números de bodegas
a las, que se determinó parámetros físicos químicos como grado alcohólico, extracto seco, acidez
total y volátil, por métodos oficiales, para el caso de compuestos polifenolicos se utilizó el método
de Folin Ciocalteu y la actividad antioxidante por los métodos del radical DPPH y FRAP. Los
resultados develan que con respecto a los parámetros fisicoquímicos la mayoría de los vinos
cumplen con los requisitos determinados en las normas técnica peruana 212.014, 2016; en cuanto
al contenido de compuestos fenólicos se reporta un contenido promedio de 1426 ± 562 mg
AGE/L, una actividad antioxidante de 2,30 ± 1,89 mM ET y 2,41± 1,63 mM ET por litro para los
métodos FRAP y DPPH respectivamente. Concluyendo que los vinos artesanales producidos en
la ciudad de Ica, presentan un contenido de polifenoles ligeramente bajos, pero una actividad
antioxidante promedio.
In recent years, there has been growing scientific interest in the secondary metabolites present in both grapes and wine, especially polyphenol compounds, enhanced by the discovery of their antioxidant properties and their role in the cure of degenerative diseases. cancer, diabetes, cardiovascular and nervous system diseases, in addition to inflammatory processes, the objective of the present study was to determine the content of polyphenol compounds and the antioxidant activity of wines produced by hand in the city of Ica, 15 samples were taken of wines from equal numbers of wineries in which physical-chemical parameters such as alcoholic strength, dry extract, total and volatile acidity were determined, by official methods, in the case of polyphenolic compounds, the Folin Ciocalteu method was used and the antioxidant activity by the DPPH and FRAP radical methods. The results reveal that with respect to the physicochemical parameters, the majority of the wines comply with the requirements determined in the Peruvian technical standards 212.014, 2016; Regarding the content of phenolic compounds, an average content of 1426 ± 562 mg AGE/L, an antioxidant activity of 2.30 ± 1.89 mM and 2.41 ± 1.63 mM per liter for the FRAP and DPPH methods is reported. respectively. Concluding that the artisanal wines produced in the city of Ica have a slightly low polyphenol content, but an average antioxidant activity.
