Resumen

El aguacate (Persea americana Mill.) es una fruta originaria de Centroamérica, y tiene un alto valor nutricional. La pulpa es la más consumida en forma de postre, ensaladas, salsas y cosméticos. Varios estudios informan que el aceite de pulpa de aguacate tiene una alta concentración de ácidos grasos insaturados que proporcionan efectos beneficiosos para la salud. El aceite se extrajo de cuatro variedades de aguacate (Quintal, Fortuna, Ouro Verde y Hass) por reflujo utilizando dos solventes, methanol y hexano, para evaluar el perfil de ácidos grasos por GC-FID, así como el potencial antioxidante mediante varios métodos (eliminación de radicales DPPH, blanqueo de β-caroteno, prueba de poder reductor y degradación de desoxirribosa). Los aceites tuvieron un contenido de humedad moderado, y el rendimiento más expresivo se obtuvo con hexano, principalmente para las variedades Quintal y Hass. El porcentaje de los principales ácidos grasos varió según el disolvente utilizado, pero en todos los aceites se identificaron los ácidos oleico, palmítico, linoleico, palmitoleico y linolénico. No se observó potencial antioxidante para los aceites por los métodos utilizados.
