الوصف: Dietary patterns that include regular consumption of prebiotic compounds are capable of modulating the composition and metabolism of the human intestinal microbiota, playing an important role in the health of the host. Red beet (Beta vulgaris L.) is an important vegetable species with a considerable supply of nutrients and bioactive compounds, especially dietary fiber, phenolic compounds and betalains. The aim of this study was to evaluate the prebiotic potential of freeze-dried products obtained from different parts of red beet by checking their effects on the growth and metabolism of probiotic strains (Lactobacillus acidophilus LA-05, Lacticaseibacillus casei L-26 and Limosilactobacillus fermentum 296) and the human colonic microbiota under in vitro conditions. The tests were carried out with freeze-dried parts of the root (FDBR) and stalk/leaf (FDBSL) of the red beet cultivar Early wonder. FDBR and FDBSL were analyzed to determine their nutritional composition and physicochemical parameters. Next, Lactobacillus strains were exposed to simulated conditions of the gastrointestinal tract in the presence of FDBR and FDBSL, when aspects related to cell viability and physiological functionality, total antioxidant capacity and total phenolic compounds were evaluated after the three main phases of digestion (mouth, stomach and intestine). In a second stage, new samples of FDBR and FDBSL were subjected to simulated gastrointestinal digestion and the digestion product was evaluated in fermentation trials using them as the sole carbon source for the cultivation of probiotic strains and to assess the modulation of the colonic microbiota using fecal inoculum. The prebiotic activity score was calculated and microbial metabolic activity was monitored by determining pH and the content of sugars and organic acids in the different cultivation systems. The phenolic profile and total antioxidant capacity were also monitored during the simulated digestion and fermentation phases with fecal inoculum. FDBR and FDBSL showed high ...
