Addition of proteic nitrogen during alcoholic fermentation for the production of cachaça Scientia Agricola
Jeronimo,Elisangela Marques; Oliveira,Evelyn de Souza; Souza,Elson Luíz Rocha; Silva,Marcelo de Almeida; Serra,Gil Eduardo.
Cachaça is the denomination of a typical and exclusive Brazilian spirit produced from the distillation of fermented sugarcane juice must. The objective of this study was to evaluate the effect of adding yeast extract to the sugarcane juice used for sugarcane liquor production, because for the artisanal process no studies are available on nitrogen addition nor beverage quality, involving nitrogen complementation. Results of previous studies in the laboratory scale showed that sugarcane juice complementation with proteic nitrogen can be a beneficial practice for yeast multiplication and cellular growth, and also for the improvement of fermentation yield and liquor productivity. In this pilot scale study, using recycled yeast, the addition of proteic nitrogen...

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...

Caractérisation de bactéries lactiques psychrotrophes en vue de leur utilisation dans la biopréservation des aliments. Étude physiologique et moléculaire des mécanismes d’adaptation au froid ArchiMer
Matamoros, Sebastien.
Lactic acid bacteria strains were isolated from seafood products and clustered according to their inhibiting capacities against 14 food borne spoiling and pathogenic strains in order to develop applications in biopreservation. Most of the strains were identified as Leuconostoc gelidum and Lactococcus piscium. Detailed identification of one strain of the Lactococcus piscium strains suggests that it is a new specie. According to sensory analysis results, 2 strains belonging to the Leuconostoc gelidum specie were the most efficient for the enhancement of the shelf life of vacuum packed peeled and cooked shrimps. Similar results were obtained in cold smoked salmon with one strains of Lactococcus sp. A challenge test against three pathogenic strains (Listeria...
