Efecto del deshuesado de la aceituna sobre el aroma del aceite de oliva virgen

Abstract

El deshuesado de la aceituna da lugar a una importante modificación del aroma del aceite de oliva virgen. La intensidad de esta modificación es característica de cada variedad. En los aceites obtenidos de aceitunas Verdial y Manzanilla se produce un incremento en el contenido de los compuestos de seis átomos de carbono (C6) que no se detecta en la variedad Picual. En las tres variedades estudiadas se observa un descenso del contenido de compuestos de cinco átomos de carbono (C5) así como del contenido en ésteres. En la variedad Verdial se ha comprobado que la modificación del aroma como consecuencia del deshuesado del fruto se debe tanto al daño tisular generado durante este proceso como a la ausencia de la semilla durante la molturación de la aceituna. Ambos factores contribuyen de forma independiente a la modificación del contenido de compuestos C6, C5 y ésteres en el aroma del aceite de oliva virgen procedente de aceituna deshuesada.

Olive fruit stoning gives rise to an important modification in olive oil aroma. The level of this modification is a function of the cultivar. An increment in the content of six-carbon compounds (C6) was observed in olive oils obtained from the cultivars Verdial and Manzanilla, but not in the cultivar Picual. In the three cultivars under study, contents of five-carbon compounds (C5) and esters decreased as a consequence of fruit stoning. The modification of olive oil aroma composition in the cultivar Verdial caused by olive fruit stoning was observed to be due both to tissue wounding and to the absence of the olive seed during the crushing-malaxation process to obtain olive oil aroma. Both factors contribute independently to the content modification of C6, C5 compounds and esters in the olive oil aroma from stoned fruits.

El trabajo se ha realizado en el marco del Proyecto de Investigación AGL2002-02307 del Programa Nacional de Recursos y Tecnologías Agroalimentarias.
