Scholarcy highlights

  • Hydroxytyrosol is a highly potent antioxidant originating in nature as a second metabolite of plants, most abundantly in olives
  • As olive oil is a prime constituent of the health-promoting Mediterranean diet, HT has obtained recognition for its attributes, supported by a recent health claim of the European Food Safety Authority
  • HT is already used as a food supplement and in cosmetic products, but it has the potential to be used as a food additive and drug, based on its anticarcinogenic, anti-inflammatory, antiapoptotic and neuroprotective activity
  • The challenges of producing HT using biotechnological methods are described with an emphasis on the substrate source, the biocatalyst and the process parameters, in order to narrow the gap towards an efficient bio-based industrial process
