Chewing behavior of high-protein expanded pea flour. 5. international conference on Food oral processing
PARI 2010-2011 - Projet DINOS "Innovinaroma" ou Mélanges d'odorants et milieux complexes
2011
L'idée est de réaliser une méta-analyse non ciblée de données d'origines multiples afin de prendre en compte à la fois les résultats de l'analyse sensorielle établie sur le concept de typicité mais aussi celles de l'olfactométrie séparative, de l'analyse semi-quantitative, de la chimie des odorants identifiés, de la psychophysique et de l'aromatique alimentaire. Le statut de composés clés porteurs de typicité aromatique, relève de leur présence en mélange dans des gammes de concentrations et dans un environnement à la fois complexe et diversifié propre à la catégorie sensorielle cible. Les approches, dont le but était de faire émerger un tel groupe d'odorants, jusqu'ici trop simplistes ou t…
Improvement of partition coefficients determination of aroma compounds in food matrices by the phase ratio variation method
2011
The Phase Ratio Variation (PRV) method is a very valuable method commonly used for liquid/vapor partition coefficients data acquisition of aroma compounds. Nevertheless, some limits are linked to this method, especially for volatile compounds. A careful examination of the PRV equation leads us to propose the following expression: 1/Cvap-real =(nliq/n0) x 1/Cvap-ideal = (nliq/n0) x (1/KC0 + (1/Co) b), We performed an examination for two cases of K values (K1=0.001 and K2=0.05), putting forward that a carefully choice of b range values is crucial for reliability of the regression calculation 1/A versus b.

Evolutionary advantage conferred by an eukaryote-to-eukaryote gene transfer event in wine yeasts
2015
Although an increasing number of horizontal gene transfers have been reported in eukaryotes, experimental evidence for their adaptive value is lacking. Here, we report the recent transfer of a 158-kb genomic region between Torulaspora microellipsoides and Saccharomyces cerevisiae wine yeasts or closely related strains. This genomic region has undergone several rearrangements in S. cerevisiae strains, including gene loss and gene conversion between two tandemly duplicated FOT genes encoding oligopeptide transporters. We show that FOT genes confer a strong competitive advantage during grape must fermentation by increasing the number and diversity of oligopeptides that yeast can utilize as a s…
