The authors regret that there was an error in the calculation of dry matter gastric emptying affecting both Fig. 5 and Table 6. This error does not affect a significant portion of the data in the article, only a single parameter, and does not change the trends or interpretation of the data. The correct version of Fig. 5 and Table 6 are given below.

Fig. 5 Gastric emptying of dry matter (A and C) and whole stomach content (B and D) of pigs fed with wheat-based diets (A and B) or rice-based diets (C and D) during 240 min of digestion. Points represent measured values (mean ± SEM n ≥ 5 for each diet × time, except rice grain × 60 min (n = 4)). Dashed lines represent the predicted dry matter gastric emptying profile based on modified exponential model (eqn (2)) or predicted total meal gastric emptying profile based on linear-exponential model (eqn (3)). Dry matter half-emptying times from (A) and (C) were plotted against initial median particle area (E) of the cooked diets or gastric softening half-time (F). Gastric softening half-time for each diet was represented by the longest softening half-time between the proximal and distal stomach regions for each diet. Note that the x-axis for (E) and (F) is shown on a log-scale due to the wide range of the values across the six diets.

Table 6 Gastric emptying parameters (expressed as predicted parameter ± 95% confidence interval) and predicted emptying half-time of dry matter and whole stomach content. Note that the confidence interval for k_whole and β_whole of semolina was very wide due to the lack of initial increase in its W_t/W₀ profile (Fig. 5B) that was supposed to be predicted by the linear-exponential model. Despite the wide confidence interval, the linear-exponential model still fit well to the data
