Cover Story: This work proved that the olive species shows a high variability in terms of content of volatile compounds in virgin olive oil, which is responsible for its characteristic aroma. In this sense, the multivariate analysis allows the identification of olive cultivars which are particularly interesting due to their volatile composition that can be used both to identify old olive cultivars that give rise to oils with a high organoleptic quality, and in parent selection for olive breeding programs.

  • Josefina Vergara-Sánchez

Bisphenol A (BPA), 4-nonylphenol (4NP), estradiol (E2), and ethinylestradiol (EE2) are considered as endocrine disruptors or mutagens. These compounds are commonly called endocrine disrupter chemicals (EDCs). BPA and 4NP are widely used as plastic ad...
