**6. Conclusions**

Olive oil is an important food in the Mediterranean diet. Its importance and nutritional value arise from chemical composition. Its richness in essential fatty acids is behind their health-promoting properties. A set of other minor compounds such as polyphenols and tocopherols act as antioxidants which are directly associated with oxidative stability and shelf life of olive oil on one hand as well as human health on the other hand. Along with these endogenous antioxidants, olive oil quality can be enhanced through natural antioxidants extracted from herbs and agri-food residues.
