Currently, a notable increase in the use of vegetable oils is being experienced, including that obtained from quinoa (Chenopodium quinoa), due to the benefits it brings in different areas, due to the importance of research that reveals its characteristics. Objective: To determine the physicochemical properties of the acceptance of different varieties of quinoa cultivated in Huancavelica, to identify variations and similarities. Materials and methods: The investigation was based on a completely random experimental design with three replications for each treatment. The extraction of acceptances was carried out applying the AOAC method, 2003.05, using the Soxtherm Soxhlet Extractor System. Results: The range of acidity indices was obtained (0.61±0.061-0.81±0.061 mg KOH/g); peroxide (1.39±0.006-1.50 ± 0.010 m-eqo2/kg); of iodine (131.7±3.06-142.3±3.79); saponification (178.0±1.00-189.0±0.00); specific gravity (0.899±0.011-0.955± 0.003) and performance (8.973± 0.064-10.887± 0.179). Conclusions: The characterization carried out constitutes a source of consultation that supports the selection of those varieties that are relevant for use by nutritionists, healthcare personnel, the cosmetics industry sector, between others; in addition to contributing to scientific knowledge about the varieties studied.
