Table 3: Best-fit line (R > 0.99) equation for the linear portion for the H\({}_{\text{p/p}}\) intensity against incubation time at 70 \({}^{\circ}\)C graphs obtained for EVOO samples both not irradiated and UV irradiated for 30, 60, and 120 min. of severaltocopherol isoforms (\(\alpha\), \(\gamma\), and \(\delta\); see Table 1) which differently absorb the energy from UV radiation, thus becoming radicals able to bind to the PBN and undergoing depletion independently and not in synchrony. The behavior of AKO samples is depicted in Figure 5.  
The AKO not-irradiated sample showed a linear trend from the IT to 180 min. The slopes of straight lines obtained for samples irradiated for 30 and 60 min were not significantly different. In contrast, for the 120 min irradiated sample, after about 110 min of thermal incubation, the H\({}_{\text{p/p}}\) intensity quickly decreases, due to alteration of the lipid matrix following exhaustion of the antioxidant components. The experimental data were fitted with a straight-line equation, and the slopes obtained from the best-fit line are reported in Table 5. As reported, the slope of the obtained straight line is 2.3-times higher for the 120 min irradiated sample compared to the not-irradiated one. Finally, the behavior of JO samples is depicted in Figure 6. \begin{table}

Table 5: Best-fit line (R > 0.99) equation for the linear portion for the H\({}_{\text{p/p}}\) intensity against incubation time at 70 \({}^{\circ}\)C graphs obtained for SAO samples both not irradiated and UV irradiated for 30, 60, and 120 min. As reported, a sharp linear increase in the \(\rm H_{p/p}\) intensity during storage at 70 \({}^{\circ}\)C as observed for all the studied samples; no plateau phase or intensity reduction were found after 120 min of UV irradiation. The experimental data were fitted with a straight-line equation, and the slopes obtained from the best-fit line are reported in Table 6. As reported, the slope of the obtained straight line is less than doubled for the 120 min irradiated sample compared to the not-irradiated one. Furthermore, for all the JO samples, the linearity region went from the IT to 180 min. This phenomenon could be attributed to the composition of JO which is almost 98% pure waves and antioxidants (\(\alpha\), \(\gamma\), and \(\delta\)tocopherol) which confer high thermal and oxidative stabilities.
