(a–d) Lowercase letters are used for comparing values within treatments. Values (mean ± SD) in the same row with different superscripts are significantly different (P < 0.05).

(A, B) Uppercase letters are used for comparing values within the same treatment during the storage. Values in the same column for the same property, with different superscripts, are significantly different (P < 0.05).
