  1. SD standard deviation, VSCs volatile sulfur compounds.
  2. aAnalysis of variance and Tukey’s paired comparison test were used to compare the mean values among the three groups.
  3. bResults were obtained using a two-sided test (two-sided).
  4. Statistical significance was set at P < 0.05. *p < 0.05, **p < 0.01. Significant values are given in bold.
