Effect of different gastric digestions (15 mg protein/mL) and the enzyme control on CCK (A), PYY (B), and active ghrelin (C) pig duodenum secretion in explants. The incubation period was 60 min for CCK and PYY and 90 min for active ghrelin secretion, all after 15 min of stabilization. The sample size was control (KRB buffer with D-glucose 10 mM) n = 9, treatments n = 6. Results are expressed as the mean ± SEM. One-way ANOVA and Tukey’s post-hoc test were used for multiple comparisons. Different letters (a, b, c) indicate significant differences (p-values < 0.05).
