  1. Data are Mean ± SEM
  2. Abbreviations: NS not statistically significant
  3. Mean that have no superscript in common are significantly different from each other. P-values <0.05 were considered as significant
  4. 1PA describes differences between coffee types at a specific time point
  5. 2PB describes differences between time points for every coffee type
