The Effect of Mucilage Pectin and Extract Added to a Food Matrix on the Gut Microbiota of Lean Humans and Humans with Obesity.

Experimental studies have provided evidence that physicochemical interactions in the food matrix can modify the biologically beneficial effects of bioactive compounds, including their effect on gut microbiota. This work aimed to evaluate the effect of a food gel matrix with cladodes mucilage pectin and extract on the growth of four beneficial gut bacteria obtained from the fecal microbiota of people who are lean or who have obesity after digestion in the upper digestive system. To accomplish this, a base formulation of cladodes mucilage with or without extract was submitted to an ex vivo fecal fermentation in an automatic and robotic intestinal system.
