Therefore, a timely effective method for fish freshness and shelf-life evaluation is important. In this context, this study aimed to develop a sensory scheme based on the Quality Index Method (QIM) (sensory table and point system) for freshness monitorization and shelf-life prediction for Seriola dumerili from aquaculture in Madeira Island. Evaluation of appearance, texture, eyes, and gills was performed during 20 days of storage on ice (0 \u00b1 1 \u00b0C). The shelf-life prediction was supported by the analysis of microorganisms (total viable colonies, TVC, counts), texture (Torrymeter), and production of trimethylamine (TMA), evaluated by HS-SPME\u2013GC\u2013MS and validated according to Association of Official Analytical Chemists AOAC guidelines. The result is a QIM scheme with 25 demerit points, where zero indicates total freshness. From the integration of sensory analysis, microbial growth at the time of rejection (TVC, 108 cfu\/cm2 and H2S producers, 107 cfu\/cm2), texture (Torrymeter value &lt; 8), and TMA analyses (&gt;12.5 mg\/100 g), shelf-life was estimated as 12 days (\u00b10.5 days). The obtained results show the high-throughput potential of the developed method for fish freshness assessment and shelf-life prediction. This QIM scheme is a secure way to measure quality and provide users with a reliable standardized fish freshness measure.<\/jats:p>","DOI":"10.3390\/molecules24193530","type":"journal-article","created":{"date-parts":[[2019,9,30]],"date-time":"2019-09-30T05:58:33Z","timestamp":1569823113000},"page":"3530","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Freshness Assessment and Shelf-Life Prediction for Seriola dumerili from Aquaculture Based on the Quality Index Method"],"prefix":"10.3390","volume":"24","author":[{"given":"Jorge","family":"Freitas","sequence":"first","affiliation":[{"name":"CQM\u2013 Centro Qu\u00edmica da Madeira, University of Madeira, Campus Universit\u00e1rio da Penteada, 9000-039 Funchal, Portugal"}]},{"given":"Paulo","family":"Vaz-Pires","sequence":"additional","affiliation":[{"name":"ICBAS \u2013 Abel Salazar Institute for the Biomedical Sciences, University of Porto, R.
