The consumption of fishery products rich in polyunsaturated fatty acids has been increasing through filleted products and restructured products. Since food oxidation is the major cause of nutritional quality deterioration in fish products, the interest in the replacement of synthetic antioxidants with natural sources, namely in the preparation of restructured animal products such as burgers, sausages and p\u00e2t\u00e9s, has been increasing. Phenolic compounds from fruits and vegetables have recognised antioxidant properties and are therefore currently considered as good alternatives to synthetic antioxidants in the food industry. In this study, the effects of the extracts of Arbutus unedo fruits, at two concentration levels (3% and 6%), on proximate composition, physicochemical properties, oxidative stability and safety of limpets p\u00e2t\u00e9, during 90 days at refrigerated storage, were investigated. After processing, the addition of 3% and 6% of A. unedo extracts into limpets p\u00e2t\u00e9 contributed to an increase of 18% and 36% in the total phenolic content and 5% and 36% in the antioxidant capacity, respectively. During storage, the enriched limpets p\u00e2t\u00e9 with A. unedo fruit extracts at 6% was more efficient as an enhancer of oxidative stability, with 34% inhibition of lipid oxidation, highlighting the potential use of A. unedo fruits as a functional ingredient in the fish industry. Overall, the limpets p\u00e2t\u00e9 with 6% of A. unedo fruit extracts proved to be more efficient regarding microbial control, and had the lowest changes in the quality parameters such as in colour, texture and pH during 90 days at refrigerated storage.<\/jats:p>","DOI":"10.3390\/foods9060807","type":"journal-article","created":{"date-parts":[[2020,6,19]],"date-time":"2020-06-19T10:43:58Z","timestamp":1592563438000},"page":"807","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Impact of Aqueous Extract of Arbutus unedo Fruits on Limpets (Patella spp.) P\u00e2t\u00e9 during Storage: Proximate Composition, Physicochemical Quality, Oxidative Stability, and Microbial Development"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9319-2651","authenticated-orcid":false,"given":"Joaquina","family":"Pinheiro","sequence":"first","affiliation":[{"name":"MARE\u2014Marine and Environmental Sciences Centre, ESTM, Polytechnic Institute of Leiria, 2520-641 Peniche, Portugal"}]},{"given":"Sid\u00f3nio","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"MARE\u2014Marine and Environmental Sciences Centre, Polytechnic Institute of Leiria, 2520-630 Peniche, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9681-3169","authenticated-orcid":false,"given":"Susana","family":"Mendes","sequence":"additional","affiliation":[{"name":"MARE\u2014Marine and Environmental Sciences Centre, ESTM, Polytechnic Institute of Leiria, 2520-641 Peniche, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5718-0880","authenticated-orcid":false,"given":"Paulo","family":"Maranh\u00e3o","sequence":"additional","affiliation":[{"name":"MARE\u2014Marine and Environmental Sciences Centre, ESTM, Polytechnic Institute of Leiria, 2520-641 Peniche, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4814-3177","authenticated-orcid":false,"given":"Rui","family":"Ganh\u00e3o","sequence":"additional","affiliation":[{"name":"MARE\u2014Marine and Environmental Sciences Centre, ESTM, Polytechnic Institute of Leiria, 2520-641 Peniche, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,19]]},"reference":[{"key":"ref_1","unstructured":"PCP (2016).
