Resumen:	This study explores enzymatic-assisted extraction (EAE) of fibers from mango peels and their prebiotic potential. Mango peels were treated with Pectinex®, Pectinex Smash XXL®, and Viscozyme® at various temperatures (30-50 ◦C) and times (2-6 h). Ethanolic precipitable matter (EPM) was used to estimate soluble fiber yield. Viscozyme® at 40 ◦C for 2 h produced the highest EPM (~15 g/100 g dry matter). However, control samples (30 ◦C, 2 h) preserved the most phenolic compounds (250 mg GAE/g EPM) and antioxidant activity in the EPM. In vitro fermentation of EPM showed that all fibers induced the production of SCFA, with the phenolic-richer fibers promoting a greater propionic acid production. These findings indicate that EAE is a valuable strategy to extract fibers from mango peels, but that enzymatic conditions must be fine-tuned to preserve higher concentration of phenolic compounds. The interaction between phenolics and fiber, or antioxidant dietary fiber, appears pivotal in modulating gut microbiota functionality.
