Continuous raw skim milk processing by pulsed electric field at non-lethal temperature: effect on microbial inactivation and functional properties Inra
Floury, J.; Grosset, N.; Leconte, N.; Pasco, M.; Madec, M.N.; Jeantet, R..
La tendance actuelle de l'industrie alimentaire est de proposer des alternatives aux traitements thermiques de pasteurisation. Ces traitements alternatifs doivent être efficaces sur le plan de la destruction bactérienne, mais moins sévères au plan physico-chimique, afin de garantir la qualité hygiénique des aliments tout en préservant leurs qualités nutritionnelles, sensorielles et fonctionnelles. Les traitements par champs électriques pulsés (CEP) sont souvent reconnus dans la littérature comme un des procédés innovants capables de répondre à ces nouvelles exigences. L'objectif de cette étude était donc ici d'évaluer l'efficacité de traitements en continu par CEP (impulsions électriques rectangulaires) réalisés à température non létale (T < 50 °C) sur...

Evidence for synergy in the denaturation at the air-water interface of ovalbumine, ovotransferrin and lysozyme in ternary mixture Inra
Lechevalier, V.; Croguennec, T.; Pezennec, S.; Guerin, C.; Pasco, M.; Nau, F..
The conformational changes of egg-white proteins, in a ternary-protein system, at the air–water interface have been studied. Three of the major egg-white proteins, ovalbumin, ovotransferrin and lysozyme, were studied with concentration ratios reflecting those in egg-white. Results were compared to those obtained in a previous work on protein denaturation at the air–water interface in single-protein systems (Lechevalier, V., Croguennec, T., Pezennec, S., Guérin-Dubiard, C., Pasco, M., & Nau, F. (2003). Ovalbumin, ovotransferrin, lysozyme: Three model proteins for structural modifications at the air–water interface. Journal of Agricultural and Food Chemistry 51, 6354–6361). Foaming altered the protein structure more profoundly in the mixture than in...

Proteomic analysis of hen egg white Inra
Guérin-Dubiard, C.; Pasco, M.; Mollé, D.; Désert, C.; Croguennec, T.; Nau, F..
Hen egg white is an original biological fluid in which major proteins have been widely studied, unlike the minor components. In this study, two-dimensional electrophoresis associated with mass spectrometry enabled the separation of 69 protein spots and their matching with major proteins, which were already known, and with minor proteins. Sixteen proteins were identified, and among them, two had never been previously detected in hen egg white, i.e., Tenp, a protein with strong homology with a bacterial permeability-increasing protein family (BPI), and VMO-1, an outer layer vitelline membrane protein. Thirteen proteins present a very wide polymorphism (ovotransferrin, ovomucoid, clusterin, etc.), some of them up to nine isoforms (ovoinhibitor). Eleven...

Secretome analysis of Phanerochaete chrysosporium strains CIRM-BRFM41 grown on softwood Inra
Ravalason, H.; Jan, G.; Mollé, D.; Pasco, M.; Coutinho, P.M.; Lapierre, C.; Pollet, B.; Bertaud, F.; Petit-Conil, M.; Grisel, S.; Sigoillot, J.C.; Asther, M.; Gimbert, I..
Abstract Proteomic analysis was performed to determine and differentiate the composition of the secretomes of Phanerochaete chrysosporium CIRM-BRFM41, a peroxidasehypersecretory strain grown under ligninolytic conditions and on softwood chips under biopulping conditions.Extracellular proteins from both cultures were analyzed by bidimensional gel electrophoresis and matrix-assisted laserdesorption/ionization time-of-flight tandem mass spectrometry.A total of 37 spots were identified. The secretome in liquid synthetic medium comprised mainly peroxidases,while several wood-degrading enzymes and enzymes involved in fungal metabolism were detected in biopulping cultures on softwood. This prompted an analysis of the impact of secretome modulation in the presence...
