1G′ values were measured at two angular frequencies (158 rad/sec and 39.6 rad/sec)
2All values given are means of three repetitions (x̅ ± SD); SD Standard deviation. Values with different superscript letters within the same column are different (P < 0.05)
Capital superscript letters (A–C) indicate significant differences between samples, brined at the same salt concentration, with different storage time. Lower-cased superscript letters (a–c) indicate significant differences according to the brine concentration, at the same storage time
