Values are reported as mean and standard error (n = 5). Two-way ANOVA was performed to assess the effect of fiber (cellulose and inulin), PSP, and their interaction. Differences of p < 0.05 was taken to be statistically significant. If the variance was observed in the main effect of the interaction, Tukey’s test was used for this comparison. Mean values designated by different letters (a–b) amongst the groups are significantly different (p < 0.05).
