Abstract
La quinoa (Chenopodium quinua), al igual que otros cereales, puede emplearse para la obtención de medicamentos y productos con gran valor nutricional. El objetivo de esta investigación fue caracterizar el contenido de polifenoles y la capacidad antioxidante de diez variedades de aceite de quinua, Blanca Junín, INIA 433, Hualhuas, Blanca criolla, Salcedo, Mantaro, Chupaca, Huancayo, Rosada Junín, Pasankalla, determinando sus propiedades fitoquímicas para su posible aplicación alimentaria e industrial. Los resultados revelaron una variabilidad significativa en los niveles de polifenoles entre las distintas variedades, se destacó Blanca Criolla (33.94±0.07 mg/g) por su alto contenido de polifenoles y una notable capacidad antioxidante; en contraste, la variedad INIA-433 (28.27± 0.05mg/g) presenta la menor cantidad de estos compuestos. Se comprueba una correlación positiva, significativamente alta, entre la capacidad antioxidante y el contenido de polifenoles, lo que fortalece la confiabilidad de los métodos de evaluación utilizados en las variedades de aceite de quinua examinadas. Se resalta la relevancia de seleccionar variedades con altos niveles de polifenoles para aplicaciones que busquen propiedades antioxidantes.

The objective of this research was to characterize the polyphenol content and antioxidant capacity of ten varieties of quinoa oil, Blanca Junín, INIA 433, Hualhuas, Blanca criolla, Salcedo, Mantaro, Chupaca, Huancayo, Rosada Junín, Pasankalla, determining their properties phytochemicals for possible food and industrial application. The results revealed a significant variability in the levels of polyphenols between the different varieties, Blanca Criolla (33.94±0.07 mg/g) stood out for its high polyphenol content and notable antioxidant capacity; In contrast, the INIA-433 variety (28.27± 0.05mg/g) presents the lowest amount of these compounds. A significantly high positive correlation is found between antioxidant capacity and polyphenol content, which strengthens the reliability of the evaluation methods used in the quinoa oil varieties examined. The relevance of selecting varieties with high levels of polyphenols for applications that seek antioxidant properties is highlighted.
