[Display omitted] • The effects of freeze-dried O. dillenii cladodes (FDOd) on gut microbiota were reported. • FDOd has bioactive compounds with prebiotic and antioxidant properties. • FDOd induced positive changes in intestinal microbiota composition. • FDOd induced the production of several metabolites during colonic fermentation. • FDOd kept antioxidant capacity during colonic fermentation. This study evaluated the physicochemical properties, antioxidant capacity, and potential prebiotic effects on the human intestinal microbiota of freeze-dried Opuntia dillenii (Ker Gawl). Haw] (Cactaceae) cladodes (FDOd). FDOd had high levels of total fiber (52.36 g/100 g), especially soluble fiber (33.36 g/100 g), as well as minerals, such as potassium (4415.49 mg/100 g), calcium (1593.25 mg/100 g), magnesium (853.55 mg/100 g), and phosphorus (209.04 mg/100 g), high total chlorophyll content (912.00 mg/100 g), presence of various phenolic compounds, such as catechin (41.00 mg/100 g), myricetin (785.00 mg/100 g), isorhamnetin (5.00 mg/100 g), rutin (42 mg/100 g), and antioxidant activity (ABTS•+: 0.51 µmol TEAC/g; DPPH•: 0.32 µmol TEAC/g; FRAP: 2.75 µmol FeSO4/g). Fermentation of FDOd using human fecal inoculum changed the composition and metabolic activity of intestinal microbiota, increasing the relative abundance of Ligilactobacillus (0.03 %–16.44 %), Lactiplantibacillus (0.00 %–1.11 %), and Agathobacter (1.80 %–4.23 %), and decreasing the relative abundance of Prevotella_9 (25.08 %–0.15 %) and Succinivibrio (24.77 %–1.54 %). FDOd influenced the metabolic profile of the intestinal microbiota with the production of various metabolites, including short- and medium-chain fatty acids, organic acids, essential amino acids, and other compound classes with health-promoting properties. The results indicate FDOd as a new ingredient with prebiotic properties in the human intestinal microbiota. [ABSTRACT FROM AUTHOR] |
