A–E: For each trial, different superscript letters in the same row denote differences (p ≤ 0.05) among the mean values (for the same treatment at different storage periods) according to Tukey's test. a–d: For each trial, different superscript letters in the same column denote differences (p ≤ 0.05) among the mean values (for the different treatments at a same storage period) according to Tukey's test.

Mean ± standard deviations of (+) increase or decrease (−) amounts during the storage period.
