I prodotti della pesca sono una delle eccellenze della grande cultura enogastronomica italiana. L’Italia con oltre 7900 km di coste offre una grande di varietà di prodotti ittici con una grande varietà di denominazioni dialettali. Per i loro principi nutritivi ricchi di proteine di alto valore biologico e lipidi contenenti importanti acidi grassi e vitamine particolarmente utili alla prevenzione di malattie legate all’apparato cardiocircolatorio sono una importante componente della “dieta mediterranea”. In contrapposizione a questi effetti benefici, per la loro particolare composizione biochimica e l’elevato contenuto di acqua si presentano facilmente deperibili, soggetti a contaminazioni batteriche, e chimiche legate principalmente all’attività antropica. Il presente lavoro prende in esame il mondo ittico in diversi aspetti, partendo dall’esame dell’economia legata ai prodotti ittici, il mercato ittico europeo e in particolare quello italiano. Le criticità intrinseche ed estrinseche dei prodotti della pesca, Il ruolo della tracciabilità quale strumento per garantirne la qualità, le proprietà nutritive e nutraceutiche, l’ecosostenibilità quale tema a cui il consumatore finale mostra sempre più attenzione, aspetti legati all’arrivo ne Mediterraneo di specie ittiche tossiche di origine lessepsiana, di nuove tossine ittiche emergenti grazie alla sempre maggiore richiesta di prodotti ittici e il conseguente aumento della globalizzazione della rete commerciale, di nuovi contaminati ambientali emergenti quali le microplastiche. Infine, vengono esaminati alcune tecniche strumentali di analisi in uso per garantirne la qualità, la sicurezza alimentare e l’esattezza delle informazioni che il consumatore finale deve conoscere. La parte sperimentale del lavoro si è occupata di verificare se esistesse una valida correlazione tra le tecniche di identificazione di specie di una eccellenza ittica italiana quale è il Gambero rosso di Mazara del Vallo è la sua localizzazione geografica che ne accresce il valore economico. La garanzia della sicurezza alimentare deve essere garantita attraverso una appropriata legislazione, applicazione di appropriati sistemi di certificazione della qualità, strumenti analitici versatili, portatili che garantiscano una risposta rapida e precisa, come richiesto dall’ industria ittica.

Abstract

Fish products are one of the excellences of the great Italian food and wine culture. Italy, with over 7900 km of coastline, offers a wide variety of fish products with a wide variety of dialect names. Due to their nutrients, rich in proteins of high biological value and lipids containing important fatty acids and vitamins, particularly useful for the prevention of diseases related to the cardiovascular system, they are an important component of the "Mediterranean diet". In contrast to these beneficial effects, due to their biochemical composition and high-water content, they are easily perishable, subject to bacterial and chemical contamination mainly linked to human activity. This paper examines the fish world in different aspects, starting from the examination of the economics linked to fish products, the European fish market and in particular the Italian one. The intrinsic and extrinsic criticalities of fishery products, the role of traceability as a tool to guarantee their quality, nutritional and nutraceutical properties, eco-sustainability as an issue to which the end consumer shows more and more attention, aspects related to the arrival in the Mediterranean of toxic fish species of Lessepsiana origin, of new emerging fish toxins thanks to the increasing demand for fish products and the consequent increase in globalization of the commercial network, of new emerging environmental contaminants such as microplastics. Finally, some instrumental analysis techniques in use are examined to ensure quality, food safety and the accuracy of the information that the final consumer must know. The experimental part of the work was concerned with verifying whether there was a valid correlation between the techniques for identifying species of an Italian fish excellence such as the Red Shrimp of Mazara del Vallo and its geographical location that increases its economic value. The guarantee of food safety must be ensured through appropriate legislation, the application of appropriate quality assurance systems, versatile, portable analytical instruments that guarantee a rapid and precise response, as required by the fishing industry.
