Antioxidant molecules were recovered during the pectin purification process, further recovering matter from the waste. Seven molecules were identified and quantified, and the antioxidant power of the mixture and its stability over time was evaluated. To improve the stability of the bioactive fraction, this was complexed with 2-hydroxypropyl-\u03b2-cyclodextrin (HP-\u03b2-CD); indeed, this procedure increased their thermal stability from 120 \u00b0C up to 250 \u00b0C, as verified by thermogravimetry. Furthermore, the most promising complexes were studied under autoclave-like conditions (120 \u00b0C, 28 min) to simulate thermal sterilization. The antioxidants and HP-\u03b2-CD were combined in a pectin film, showing increased stability over time (up to three times) compared to uncomplexed antioxidants. This process represents a first step towards the development of applicable devices for the delivery of antioxidant molecules.<\/jats:p>","DOI":"10.3390\/antiox12030763","type":"journal-article","created":{"date-parts":[[2023,3,21]],"date-time":"2023-03-21T03:15:03Z","timestamp":1679368503000},"page":"763","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Host\u2013Guest Complexes HP-\u03b2-CD\/Citrus Antioxidants: Exploratory Evaluations of Enhanced Properties in Biodegradable Film Packaging"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6846-6526","authenticated-orcid":false,"given":"Giovanni","family":"Gallo","sequence":"first","affiliation":[{"name":"Department of Biology, University of Naples Federico II, Complesso Universitario di Monte Sant\u2019Angelo, 80126 Napoli, Italy"},{"name":"Division of Microbiology, Faculty of Biology, Ludwig-Maximilians-Universit\u00e4t M\u00fcnchen, 82152 Martinsried, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2855-748X","authenticated-orcid":false,"given":"Domenico","family":"Zannini","sequence":"additional","affiliation":[{"name":"Institute of Polymers, Composites and Biomaterials, National Research Council, Via Campi Flegrei 34, 80078 Pozzuoli, Italy"},{"name":"Department of Chemical Sciences, University of Naples Federico II, Complesso Universitario di Monte Sant\u2019Angelo, 80126 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara","family":"Immirzi","sequence":"additional","affiliation":[{"name":"Institute of Polymers, Composites and Biomaterials, National Research Council, Via Campi Flegrei 34, 80078 Pozzuoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5801-0752","authenticated-orcid":false,"given":"Alessandra","family":"De Bruno","sequence":"additional","affiliation":[{"name":"Department of AGRARIA, University Mediterranea of Reggio Calabria, 89124 Reggio Calabria, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4089-3822","authenticated-orcid":false,"given":"Gabriella","family":"Fiorentino","sequence":"additional","affiliation":[{"name":"Department of Biology, University of Naples Federico II, Complesso Universitario di Monte Sant\u2019Angelo, 80126 Napoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8108-1102","authenticated-orcid":false,"given":"Giovanni","family":"Dal Poggetto","sequence":"additional","affiliation":[{"name":"Institute of Polymers, Composites and Biomaterials, National Research Council, Via Campi Flegrei 34, 80078 Pozzuoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1016\/j.nut.2016.09.006","article-title":"Converting Citrus Wastes into Value-Added Products: Economic and Environmently Friendly Approaches","volume":"34","author":"Sharma","year":"2017","journal-title":"Nutrition"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"203","DOI":"10.1016\/j.cej.2006.02.015","article-title":"Water-Based Extraction of Pectin from Flavedo and Albedo of Orange Peels","volume":"120","author":"Liu","year":"2006","journal-title":"Chem.
