Última Valorisation de matières premières marines de faible valeur ajoutée : application aux co-produits de thon ArchiMer Nguyen, Thi-my-huong. The main objective of this study is the valorisation of by-products coming from processed tuna (Thunnus albacares). Therefore, enzymatic hydrolysis was selected, using an industrial large spectrum protease (Protamex). In a first phase, hydrolyses of these by-products (heads, tails, viscera) were carried out for long periods of time (12h) in order to establish the kinetics of the proteolysis of those different by-products and to obtain the approximate composition of the different resulting fractions and to determine the conditions which would allow the valorisation of these fractions. In a second phase the valorisation in animal nutrition (shrimp culture) and in human nutrition (fish sauce) of the fractions coming from the hydrolysis of the head of tunas...

Ano: 2009 URL: http://archimer.ifremer.fr/doc/2009/these-6918.pdf Valorisation des coproduits issus de la pêche des céphalopodes : applications à la seiche Sepia officinalis ArchiMer Le Bihan, Estelle. The cuttlefish Sepia officinalis, is one of the main species capted in the Basse-Normandie fisheries. These animals are principally exportated in eviscerated and frozen form to mediteranean countries and to Japan. Then, high quantities of co-products are available from factories transformation of cephalopods. Enzymological and biochemical studies on co-products demonstrated an elevated potential in the valorisation of viscera by silage technical. Two silages are developed in our laboratory: LBBMA4 and LBBMA25. Primarly, they are studed in vitro as substrate for the culture of micro-organisms. This study established that silage LBBMA25 permits to obtain good growth cinetic and biomass, with comparable results to commercial peptone. Secondary, silages can be...

Ano: 2006 URL: http://archimer.ifremer.fr/doc/2006/these-3674.pdf Extraction de lipides en voie aqueuse par bioréacteur enzymatique combine à l'ultrafiltration : application a la valorisation de co-produits de poisson (Sardina pilchardus) ArchiMer Dumay, Justine. The main goal of this work was to up-grade sardine (Sardina pilchardus) by-products using mild procedure, environmentally sound, in order to obtain valuable compounds involving moderate investment and low energy consumption. Hydrolysis and ultrafiltration techniques have been investigated. Firstly, selected enzymes have been calibrated in order to determine their optimal conditions with a model substrate and to permit the comparison between them. Then, hydrolysis on sardine head and viscera have been carried out in two steps. The first one had the objective to determine the enzyme efficiency and the study area. The second step was to optimise enzymatic hydrolysis using experimental designs. The aim of this second step was to obtain the highest lipid...
