Aromas potentiality of tuna cooking juice concentrated by nanofiltration ArchiMer
Walha, Khaled; Ben Amar, Raja; Masse, Anthony; Bourseau, Patrick; Cardinal, Mireille; Cornet, Josiane; Prost, Carole; Jaouen, Pascal.
Tuna cooking juices contain high organic load preventing the rejection in the environment without treatment. But the effluents present an interesting fishy odour and it is worth recovering aroma compounds. In this work, two industrial tuna cooking juices were concentrated by nanofiltration. Nanofiltration performance was discussed in terms of permeation fluxes, organic matter retention and impact on the aromatic properties of juices. NF sharply decreases the global intensity of juices and modifies their aromatic equilibrium. However, the main characteristics and the marine nature of juices were kept. A pre-treatment by microfiltration (MF) induces a marked increase in permeation fluxes during NF concentration while it slightly affects the aromatic...

Concentration and purification of Porphyridium cruentum exopolysaccharides by membrane filtration at various cross-flow velocities ArchiMer
Balti, Rafik; Le Balc'H, Romain; Brodu, Nicolas; Gilbert, Marthe; Le Gouic, Benjamin; Le Gall, Sophie; Sinquin, Corinne; Masse, Anthony.
Exopolysaccharides (EPS) from cell-free Porphyridium cruentum media were concentrated then purified (diafiltration) on a 0.14 µm ceramic membrane. The influence of cross-flow velocities on filtration performances was investigated. Mean permeate fluxes equal to 49.8, 68.9 and 81.9 L.h-1. m-2 were obtained during the concentration at 4 bar for respectively cross-flow velocities inside the membrane lumen equal to 2.5, 3.3 and 4.2 m.s-1; 49.7 L.h-1. m-2 for the diafiltration at 3.3 m.s-1. Permeate fluxes were correctly predicted from polysaccharide concentrations (10 % deviation). Volume reduction factors higher than 7.8 were reached. Rejection rates of polysaccharides and proteins varied according to the cross-flow velocities. Thus, the EPS recovery rate or...

COSELMAR, a 4-year project financed by the Région des Pays de la Loire at 2.1 M€, officially started on the 7th January 2013. The project is coordinated by Philipp Hess (IFREMER) and Sophie Pardo (Université de Nantes-LEMNA) and falls under the Federation for Research Institut Universitaire Mer et Littoral (IUML, FR CNRS 3473)*. COSELMAR has also been approved by the Scientific Council of the MSH Ange Guépin. COSELMAR is a research project uniting 5 research units of IFREMER and 11 laboratories of the Université de Nantes, along with academic partners, and national and international industries. The aim is to achieve a better understanding of the marine and coastal ecosystems and the associated resources. The project will also provide insights into risk...

Enzymatic hydrolysis combined to membranes for upgrading seafood by-products ArchiMer
Bourseau, Patrick; Chabeaud, Aurélie; Vandanjon, Laurent; Masse, Anthony; Jaouen, Pascal; Fleurence, Joël; Berge, Jean-pascal.
This review reports some interesting works on the recovery and fractionation by membrane techniques of marine compounds resulting from hydrolysis of fish by-products such as proteins or peptides, lipids or fatty acids, and carbohydrates. Ultrafiltration (UF) appears as the most widely used technique for such applications. It must be noted that only a few works deal with the optimization or the enhancement of processes for the recovery of added value molecules. Indeed, most of works use UF as a convenient and simple tool for solute fractionation, for this reason the influence of operating parameters on membrane separation efficiency is unfortunately seldom considered. When attention is paid in a study to the process development, it is specified in this...

Fractionation of fish protein hydrolysates by ultrafiltration and nanofiltration: impact on peptidic populations ArchiMer
Bourseau, Patrick; Vandanjon, Laurent; Jaouen, Pascal; Chaplain-derouiniot, Maryse; Masse, Anthony; Guerard, Fabienne; Chabeaud, Aurélie; Fouchereau-peron, Martine; Le Gal, Yves; Ravallec-ple, Rosenn; Berge, Jean-pascal; Picot, Laurent; Piot, Jean -marie; Batista, Ireneu; Thorkelsson, Gudjon; Delannoy, Charles; Jakobsen, Greta; Johansson, Inger.
The production by enzymatic treatment of fish protein hydrolysates (FPH) is a promising route to add value to fisheries proteinic co-products (fish frames, heads etc.). Indeed, FPH possess good nutritional properties and biological activities for food and feed uses. Pressure-driven membrane separations such as ultrafiltration (UF) and nanofiltration (NF) can be used after the hydrolysis to, increase the specific activities of the FPH. This paper discusses the impact of a two-step UF/NF process producing four different fractions on two industrial FPH with different hydrolysis degrees. Fractionation is carried out in "realistic" conditions for an industrial process, on highly concentrated FPH solutions (about 100 g of dry matter/L) at a high volume reduction...

Impact of granular filtration on ultrafiltration membrane performance as pre-treatment to seawater desalination in presence of algal blooms ArchiMer
Sabiri, Nour-eddine; Sechet, Veronique; Jaouen, Pascal; Pontie, Maxime; Masse, Anthony; Plantier, Severine.
To mitigate fouling of the ultrafiltration (UF) membrane and improve permeate quality, we coupled granular filters (GF) with UF membrane as a pre-treatment for reconstituted seawater in the presence of algal bloom. Mono and bilayer granular filtrations were led at a mean velocity of 10 m h(-1) over a 7-hour period. Both GF gave the same algal cell retention rate (similar to 63%) after 7 hours of filtration. Turbidity reduction rate was 50% for the monolayer filter and 75% for the bilayer filter. Resulting organic matter removal rate was 10% for the monolayer filter and 35% for the bilayer filter. Dissolved organic carbon removal was low (20%) with the bilayer filter and non-existent with the monolayer filter. GF-coupled UF reduced humic acids in the...

Performances of dead-end ultrafiltration of seawater: from the filtration and backwash efficiencies to the membrane fouling mechanisms ArchiMer
Masse, Anthony; Arab, Oumnia; Sechet, Veronique; Jaouen, Pascal; Pontie, Maxime; Sabiri, Nour-eddine; Plantier, Severine.
The present work investigates the fouling mechanisms of PVDF hollow fibre membrane (0.03 μm) during the dead end ultrafiltration at a fixed permeate flux (outside to inside configuration) of complex synthetic seawater composed by humic acids, alginic acids, inorganic particles and numerous salts at high concentrations. Short term ultrafiltration experiments at 100 L.h-1.m-2 show that the optimal specific filtered volume seems to be equal to 50 L.m-2. A residual fouling resistance equal to 2.1010 m-1 is added after each cycle of filtration during 8h of ultrafiltration at 100 L.h-1.m-2 and 50 L.m-2. Most of the fouling is reversible (80%). Organics are barely (15% of humic acids) retained by the membrane. Backwash efficiency drops during operation which...

Pre-purification by membrane filtration of paralytic shellfish toxins from Alexandrium minutum dinoflagellate ArchiMer
Balti, Rafik; Brodu, Nicolas; Zhang, Jiaxuan; Amzil, Zouher; Drouin, Delphine; Sechet, Veronique; Masse, Anthony.
The Paralytic shellfish neurotoxins (PST) are of increasing interest for biomedical applications. The chemical synthesis is often complex and expensive that’s why the purification by membrane filtration of PST from Alexandrium minutum dinoflagellate was investigated. Disrupted micro-alga cells by ultrasonic treatment were diafiltred to let pass toxins through an ultrafiltration membrane. Then, the mean permeate was concentrated and diafiltrated by nanofiltration. Mean permeate fluxes equal to 187, 135 and 135 L.h–1.m-2 were obtained during the first diafiltration, the concentration step and the final diafiltration respectively. Up to 57 % (mol/mol) and 78 % (mol/mol) of organic matters and salts were removed respectively. Divalent ions were sparsely...
