Each value is mean±SD (n=3).
Mean values in the same column (A-H) or row (a-c) followed by different letters are significantly different according to Duncan’s multiple range test (p<0.05).
CT, cabbage type; PC, pressure condition; BC, brine concentration.
Level of significance: NS, not significant; *p<0.05; **p<0.01; ***p<0.001.
