1. Introduction. Antioxidants exert positive effects on human health, as they protect the human body against harmful effects caused by reactive oxygen species, which damage macromolecules such as membrane lipids, proteins, and DNA and can lead to the development of several diseases, such as cancer and neurodegenerative, inflammatory, and heart diseases [1, 2].

Effect of fermentation on the antioxidant activity in plant

Upon fermentation, the degradation of phenolic compounds takes place, and the rate of this phenolic loss is responsible for the decreased antioxidant activity (Othman et al., 2009). Fermentation processing, such as olive processing, induces an important phenolic loss leading to the reduction of antioxidant value ( Othman et al., 2009 ).
