Kinetics of the phenolic enrichment of hydroxytyrosol, tyrosol and oleuropein aglycone of tomato in EVOO. Significant differences were determined by the successive difference contrast test and are labeled as “***p-value < 0.001”, “**p-value: 0.001–0.01”, “*p-value: 0.01–0.05” and “n.s. p-value > 0.05”. Concentrations were normalized before statistical analysis.
