%X El estudio se centr車 en la aplicaci車n de un dise o experimental para la determinaci車n de las condiciones m芍s idoneas de extracci車n del aceite de la almendra del corozo, para inferir a partir de las propiedades fisicoqu赤micas del mismo los posibles usos. Se utilizaron frutos maduros recolectados en Boquer車n, municipio Carlos Arvelo, estado Carabobo, del cual fueron obtenidas las almendras que se sometieron a un proceso de acondicionamiento y reducci車n de tama o. La extracci車n de aceite se realiz車 por dos procedimientos, arrastre con vapor y extracci車n con n-hexano, con la finalidad de seleccionar el m谷todo m芍s adecuado y aplicar un dise o experimental 32 estudiando el efecto sobre el porcentaje de extracci車n de aceite del tiempo de extracci車n, tama o de part赤cula y la interacci車n de ambos. La caracterizaci車n fisicoqu赤mica se efectu車 siguiendo los lineamientos descritos en las normas COVENIN para este tipo de producto. La extracci車n con n-hexano arroj車 mayores porcentajes de aceite extra赤do, siendo el m芍ximo 49,05%, cuando el tama o de part赤cula y tiempo de extracci車n fueron 0,65mm y 5 horas respectivamente. El aceite present車 56,6% de 芍cido l芍urico, lo que indica que es similar al aceite de coco y palmiste, pudiendo utilizarse en diversas aplicaciones alimenticias e industriales. The study centred on the application of an experimental design for the determination of the most suitable conditions of extraction oil of the corozo＊s kernel, to infer from the physicochemical properties of the same one the possible uses. There were in use mature fruits gathered in Boquer車n, Carlos Arvelo municipality, Carabobo state, of which there were obtained the kernels that surrendered to a process of conditioning and reduction of size. The extraction oil was realized by two procedures, dragging by steam and extraction with n-hexane, with the purpose of selecting the most suitable method and of applying an experimental design 32 studying the effect on the percentage of extraction oil of the time of extraction, size of particle and the interaction of both. The physicochemical characterization it effect following the limits described in the procedure COVENIN for this type of product. The extraction with n-hexane threw major percentages of extracted oil, being the maximum 49.05%, when the size of particle and time of extraction they were 0.65 mm and 5 hours respectively. The oil presented 56.6% of lauric acid, which indicates that it is similar to the oil of coconut and palmiste, being able to be in use in diverse nourishing and industrial applications.
