Measurements were taken every 7 d during cold storage at 5 ± 1°C, followed by a 3 d shelf life at room temperature. Each value is the mean of three replicates ± standard error (SE). Values with different lowercase letters on the same storage period indicate a significant difference () according to Duncan’s multiple range test. The abbreviated treatment details: 0 (control), 50 µM for 90 min (T1), 50 µM for 120 min (T2), 50 µM for 150 min (T3), 100 µM for 90 min (T4), 100 µM for 120 min (T5), 100 µM for 150 min (T6), 150 µM for 90 min (T7), 150 µM for 120 min (T8), and 150 µM for 150 min (T9).
