This study aims to investigate the effect of Codium tomentosum seaweed extract (SE) incorporation in alginate and chitosan edible films. Alginate- and chitosan-based films with and without the incorporation of 0.5% SE were characterized according to their physical, optical, mechanical, and thermal properties. Seaweed extract incorporation in chitosan films resulted in an increase of film solubility (50%), elasticity (18%), and decrease of puncture strength (27%) and energy at break (39%). In alginate films, the extract incorporation significantly decreased film solubility (6%), water vapour permeability (46%), and elasticity (24%), and had no effect on thermal properties. Depending on the type of application, the addition of SE in edible films can bring advantages for food conservation.<\/jats:p>","DOI":"10.3390\/foods7040053","type":"journal-article","created":{"date-parts":[[2018,4,2]],"date-time":"2018-04-02T12:32:20Z","timestamp":1522672340000},"page":"53","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":54,"title":["Influence of Codium tomentosum Extract in the Properties of Alginate and Chitosan Edible Films"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8561-6848","authenticated-orcid":false,"given":"Ana","family":"Augusto","sequence":"first","affiliation":[{"name":"MARE\u2014Marine and Environmental Sciences Centre, ESTM, Instituto Polit\u00e9cnico de Leiria, 2520-641 Peniche, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7079-1069","authenticated-orcid":false,"given":"Juliana","family":"Dias","sequence":"additional","affiliation":[{"name":"Centre for Rapid and Sustainable Product Development (CDRsp), Instituto Polit\u00e9cnico de Leiria, 2430-028 Marinha Grande, Portugal"},{"name":"I3S-Instituto de Investiga\u00e7\u00e3o e Inova\u00e7\u00e3o em Sa\u00fade, Universidade do Porto, 4200-135 Porto, Portugal"},{"name":"INEB-Instituto de Engenharia Biom\u00e9dica, Universidade do Porto, 4150-180 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0883-0610","authenticated-orcid":false,"given":"Maria","family":"Campos","sequence":"additional","affiliation":[{"name":"MARE\u2014Marine and Environmental Sciences Centre, ESTM, Instituto Polit\u00e9cnico de Leiria, 2520-641 Peniche, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5016-0868","authenticated-orcid":false,"given":"Nuno","family":"Alves","sequence":"additional","affiliation":[{"name":"MARE\u2014Marine and Environmental Sciences Centre, ESTM, Instituto Polit\u00e9cnico de Leiria, 2520-641 Peniche, Portugal"}]},{"given":"Rui","family":"Pedrosa","sequence":"additional","affiliation":[{"name":"MARE\u2014Marine and Environmental Sciences Centre, ESTM, Instituto Polit\u00e9cnico de Leiria, 2520-641 Peniche, Portugal"}]},{"given":"Susana","family":"Silva","sequence":"additional","affiliation":[{"name":"MARE\u2014Marine and Environmental Sciences Centre, ESTM, Instituto Polit\u00e9cnico de Leiria, 2520-641 Peniche, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2018,4,1]]},"reference":[{"key":"ref_1","unstructured":"Bourtoom, T.
