The physicochemical attributes and microbial decontamination of oils extracted from gamma-irradiated almond (Mission and Price varieties) seeds, to the absorbed doses of 2-10 kGy, have been evaluated. Gamma irradiation exerted no considerable effect on the proximate seed composition. The physicochemical properties such as density and refractive index of the oils, extracted from gamma-irradieted seeds, were almost unaffected; the iodine value decreased while saponification value, unsaponifiable matter and free fatty acids increased. The oxidative status and tocopherol content of almond oils were negatively affected while the fatty acid profile slightly changed due to irradiation stress. Interestingly, these effects on the oil quality attributes were more pronounced at higher irradiation doses (> 6 kGy). Besides, microbial contamination was completely eliminated in the oils irradiated to an absorbed dose of 6.0 kGy. It could be concluded from the present findings that irradiation has a considerably positive or negative effect on some attributes of the almond oil. Therefore, an appropriate magnitude of gamma irradiation should be exercised to treat almond seeds in order to retain maximum nutritive benefits.Original Abstract: Se ha evaluado las caracteristicas fisico-quimicas y la descontaminacion microbiana de aceites extraidos de semillas de almendras (variedades Mision y Price) gamma-irradiadas a dosis absorbidas de 2-10 kGy. La radiacion gamma no ejerce ningun efecto considerable en la composicion proximal de las semillas. Las caracterfsticas fisico-quimicas tales como la densidad y el (ndice de refraccion de los aceites, extraidos a partir de semillas gamma-irradiadas, permanecieron casi sin afectar; el fndice de yodo disminuye mientras que el valor de saponificacion, la materia insaponificable y los acidos grasos libres aumentan. El estado oxidativo y el contenido de tocoferoles de los aceites de almendra se vieron afectados negativamente, mientras que el perfil de acidos grasos se modifica ligeramente debido al estres de la radiacion. Curiosamente, los efectos sobre los atributos de calidad del aceite fueron mas pronunciados a dosis de radiacion mas altas (> 6 kGy). Ademas, la contaminacion microbiana se elimino por completo en los aceites irradiados a una dosis absorbida de 6,0 kGy. Se puede concluir a partir de los presentes hallazgos que la radiacion tiene un efecto positivo o negativo considerable en algunos atributos de la aceite de almendras. Por lo tanto, se debe aplicar una magnitud apropiada de radiacion gamma para el tratamiento de semillas de almendra con el fin de retener los maximos beneficios nutritivos.
