RUIZ RODRIGUEZ, Alfonso; DE LA CRUZ, Zebina Leandro e RODRIGUEZ, Perfecto Chagua. Characterization of the polyphenol content and antioxidant capacity of the oil of ten varieties of quinoa (Chenopodium quinoa). Rev. Inv. Cs. Agro. y Vet. [online]. 2024, vol.8, n.23, pp.404-413.

Quinoa (Chenopodium quinoa), like other cereals, can be used to obtain medicines and products with great nutritional value. 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.
