Resumen
[ES] La hoja de olivo es un subproducto que se genera en la industria olivarera y que se puede valorizar para la obtención de compuestos bioactivos. Estos compuestos de origen natural son cada vez más demandados por las industrias alimentaria, cosmética y farmacéutica. Este TFG estudia la recuperación de compuestos fenólicos bioactivos a partir de hoja de olivo, usando una técnica no convencional denominada extracción con líquidos presurizados. Se llevó a cabo un diseño de experimentos consistente en 12 tratamientos para evaluar la influencia de los factores tiempo y temperatura sobre el contenido fenólico total y la concentración de los principales fenoles individuales en los extractos obtenidos. El contenido fenólico total se determinó mediante el método Folin-Ciocoalteau, mientras que los compuestos fenólicos mayoritarios se identificaron y cuantificaron por HPLC. Finalmente, se aplicó la metodología de superficies para maximizar las respuestas y optimizar las condiciones de operación de la técnica.

These naturally occurring compounds are increasingly demanded by the food, cosmetic, and pharmaceutical industries. This TFG examines the recovery of bioactive phenolic compounds from olive leaves, using an unconventional technique called pressurized liquid extraction. A design of experiments consisting of 12 treatments was carried out to evaluate how time and temperature factors influenced on the total phenolic content and the concentration of the main individual phenols in the obtained extracts. The total phenolic content was determined using the Folin- Ciocoalteau method, while the major phenolic compounds were identified and quantified by HPLC. Finally, a surface methodology was applied to maximize the responses and optimize the operating conditions of the technique.
