St. Hil. plants are used for the preparation of food and drinks which are widely consumed worldwide. During the harvest season of these plants, 2\u20135\u2009ton hec<sup>\u22121<\/sup>\u00a0of agricultural residue is generated, which remains underutilized. Therefore, this study aimed to obtain an edible extract with high content of bioactive compounds and antimicrobial properties from the agricultural residue of I. paraguariensis for industrial use in food applications. The extraction conditions were optimized through a multivariate experimental design using ethanol:water. The extracted compounds were characterized by HPLC-ESY-QTOF-MS. In the optimal extraction conditions, 55 compounds were extracted, including 8 compounds that were not previously reported in\u00a0I. paraguariensis. The method proved to be simple, fast, economical and environmentally friendly, with the use of green solvents. This optimization allowed for the extraction of 15.07\u2009g of phenolic compounds per 100\u2009g of residue. The extract showed high antioxidant activity and the capacity to inhibit\u00a0Staphylococcus aureus. Results indicate that it is possible to obtain an edible extract with a high content of bioactive compounds, particularly phenolic compounds, from the\u00a0I. paraguariensis\u00a0residue, which has high prospects for the valorization of unexplored natural resources.<\/h3>\n<p><a href=\"https:\/\/doi.org\/10.1080\/03601234.2021.2020530\">https:\/\/doi.org\/10.1080\/03601234.2021.2020530<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Alexandre Lorini, Fernanda M.
