    Mango peel, a by-product of mango processing, has been identified as a valuable source of polyphenols. As such, research on the extraction of mangiferin-rich phenolic compounds from this waste peel is of great interest. The mangiferin has attracted scientific attention due to its various applications in health, nutrition and cosmetics, especially for its and cosmetics, especially for its antioxidant capacity. The extraction of phenolic compounds was carried out through response surface methodology, using dehydration, crushing, and infusion with a water-ethanol mixture at various concentrations for different time intervals. The determination of the total polyphenol content (TPC) was carried out using the Folin-Ciocalteu method, achieving a TPC of 93.5928 mg GAE per gram of dry base, with a concentration of 70 percent ethanol. The identification of mangiferin was carried out with UV-Vis and infrared spectrophotometry. The microencapsulation, using a water-extract-maltodextrin mixture, showed an efficiency of 95,146 with a total solids content of 30 percent. The radical inhibition capacity was evaluated by means of the DPPH method, obtaining promising antioxidant promising percentages of antioxidant capacity: 88.373 per cent for the crude extract and 43.165 per cent for the microencapsulated extract. In summary, this study concludes that the microencapsulation process not only overcomes the limitations associated with polyphenols, but also contributes significantly to the increase of the free radical scavenging capacity, highlighting the potential of mango peel in various industrial applications.
