Abstract:
La alcachofa es una hortaliza originaria de la región mediterránea, siendo esta zona donde mayoritariamente se localiza su producción. En los últimos años su consumo se ha extendido por todo el mundo, siendo muy apreciada por su alto contenido en compuestos bioactivos, mayoritariamente fenoles del ...  Ver más
The artichoke is a vegetable native to the Mediterranean region, this area being where its production is mostly located. In recent years its consumption has spread throughout the world, being highly appreciated for its high content of bioactive compounds, mainly phenols from the group of hydroxycinnamics and luteolins. The high polyphenol content of artichoke strains produces a greater browning during processing and for use in the fourth range, which makes its use in industry difficult. In previous works, important differences have been found in the polyphenol content of different varieties of artichoke, as well as between the type of chapters (main or guides, secondary or second and tertiary or third, according to their order of development). In this work, the polyphenol content of the chapters after commercial harvesting of the artichoke varieties Blanca de Tudela (vegetative reproduction), Lorca and Tupac (open-pollinated seed), and Green Queen (hybrid seed) have been studied. The four varieties were grown in an EPSO-UMH experimental plot, between the months of August 2020 and April 2021, following the usual practices of the area. Among the factors studied, the variety has explained 13.88% of the variability, the type of chapter 11.64% and the internal state 32.33%. The results of this work have shown varietal differences in phenolic content, and how they affect the position in the plant and the stage of development of the chapter, however, more studies are necessary to confirm the results obtained.
