Results are given as absolute and relative value, n(%). Total beverage intake = 625 ± 61 mL. Aliquot intake = 50, 30 and 20% at first (0 min), second (45 min) and third (75 min) post-FMP, respectively. The sensory acceptability criterion was the 9-point hedonic scale proposed by Meilgaard et al. (2006) [36]. x22, chi squared with df = 2 and p-value were obtained by Friedman rank sum test (used for to verify the time effect). Kendall’s W with bootstrapped 95% CI (confidence interval with bootstrap [1000 replicates recalculated from original data]) was used to describe agreement among respondents
