In each column and for each sample, means with different superscript lowercase letters are significantly different (P < 0.05). BIO: at the beginning of the oxidation (T = 0 h), BIP: before the induction period (24 h before induction period), IP: at the induction period (Table 1), AIP: after the induction period (24 h after the induction period), and PP: at the propagation phase (at the time of T_max (the time when the rate of lipid hydroperoxide production reaches its maximum value, Table 2)).
