To overcome this issue, attention has been driven to study alternative materials, namely the use of biodegradable biopolymers extracted from agro-industrial residues, as materials for food packages. In this work, the polysaccharide arabinoxylan, previously extracted from corn fibre by alkaline hydrolysis, was used to produce composite and multilayer films. The composite films were produced by casting an oil-in-water emulsion with different quantities of oleic acid, while the multilayer films (beeswax-arabinoxylan-beeswax) were manufactured by submerging the arabinoxylan films in a beeswax solution. Both film types, along with a film composed only of arabinoxylan, were characterised in terms of their antioxidant activity, optical and mechanical properties, surface hydrophobicity, and barrier properties against water vapour (WVP), gases, and ultraviolet-visible (UV-vis) radiation. All the films developed were soluble in water. The multilayer films were more advantageous than the emulsion-based ones due to their enhanced barrier properties against water vapour (WVP = 0.58 \u00d7 10\u221211 mol\/m\u2219s\u2219Pa), oxygen (with a permeability of 3.28 \u00d7 10\u221212 mol\u00b7m\u22121\u00b7s\u22121\u00b7Pa\u22121) and UV-vis radiation and higher values of water contact angle (92.43\u00b0), tensile stress (4.11 MPa), and Young\u2019s modulus (15.96 MPa). The films developed, especially the multilayer ones, showed a good potential to produce flexible packages for low-water-content food products (e.g., several types of nuts).<\/jats:p>","DOI":"10.3390\/coatings12060813","type":"journal-article","created":{"date-parts":[[2022,6,10]],"date-time":"2022-06-10T10:25:12Z","timestamp":1654856712000},"page":"813","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Development and Characterisation of Arabinoxylan-Based Composite Films"],"prefix":"10.3390","volume":"12","author":[{"given":"Joana","family":"Salvada","sequence":"first","affiliation":[{"name":"LAQV-Requimte, Department of Chemistry, NOVA School of Science and Technology, NOVA University of Lisbon, 2829-516 Caparica, Portugal"}]},{"given":"Bhavna","family":"Alke","sequence":"additional","affiliation":[{"name":"LAQV-Requimte, Department of Chemistry, NOVA School of Science and Technology, NOVA University of Lisbon, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7784-0265","authenticated-orcid":false,"given":"Carla","family":"Brazinha","sequence":"additional","affiliation":[{"name":"LAQV-Requimte, Department of Chemistry, NOVA School of Science and Technology, NOVA University of Lisbon, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4117-5582","authenticated-orcid":false,"given":"V\u00edtor","family":"Alves","sequence":"additional","affiliation":[{"name":"LEAF\u2014Linking Landscape, Environment, Agriculture and Food, Associated Laboratory TERRA, Instituto Superior de Agronomia, Universidade de Lisboa, 1349-017 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7032-3436","authenticated-orcid":false,"given":"Isabel","family":"Coelhoso","sequence":"additional","affiliation":[{"name":"LAQV-Requimte, Department of Chemistry, NOVA School of Science and Technology, NOVA University of Lisbon, 2829-516 Caparica, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,10]]},"reference":[{"key":"ref_1","unstructured":"National Geographic (2020, October 08).
