Ultrasound assisted method to increase soluble chemical oxygen demand (SCOD) of sewage sludge for digestion
2004
The aim of this study was to clarify the possibilities to increase the amount of soluble chemical oxygen demand (SCOD) and methane production of sludge using ultrasound technologies with and without oxidising agents. The study was done using multivariate data analyses. The most important factors affected were discovered. Ultrasonically assisted disintegration increased clearly the amount of SCOD of sludge. Also more methane was produced from treated sludge in anaerobic batch assays compared to the sludge with no ultrasonic treatment. Multivariate data analysis showed that ultrasonic power, dry solid content of sludge (DS), sludge temperature and ultrasonic treatment time have the most signi…
Effect of calculation methods and presence of false positives on perception thresholds
2023
Perception thresholds are commonly used in food science to discriminate between those compounds that are more or less odour-active. It is not rare to use values from other studies and apply them to our data, however, we observed that the procedure to evaluate and calculate perception thresholds is not standardised. The aim of this study was to explore the influence of calculation methods on threshold values. To do so, we used a 3-AFC sensory procedure to determine the orthonasal and retronasal detection values of 26 compounds, amongst them some compounds that usually contribute to the aroma of strawberry and caramel (e.g. vanillin, Furaneol and damascenone). The thresholds were calculated b…

Définir, dénommer et traduire l'onctuosité : regards croisés sur une propriété gustative et ses dénominations en français, anglais et allemand
2006
International audience; Un simple coup d'œil sur les rayons crèmerie d'un supermarché ou sur les prospectus publicitaires suffit à s'en convaincre : onctueux est un attribut fort prisé en marketing alimentaire. Un test rapide sur google le confirme par ailleurs : pour les seules structures N + A, le moteur de recherche fournit une multitude d'occurrences pour ce domaine avec des syntagmes comme fromage blanc onctueux, potage onctueux mais aussi bûche de Noël au cœur onctueux, riz onctueux ou encore beurre de pomme onctueux. L'objectif de cette contribution est ainsi d'interroger les multiples emplois de l'adjectif onctueux en français et d'en envisager les équivalents possibles en anglais e…

Variabilité climatique et profils organoleptiques du Pinot noir dans le monde
2015
Wine typicity is revealed at various spatial scales, according to the variability of terroir components, which individual contribution change depending on the site. In this study, the impact of climate at global scale on the sensory profile of wine is examined.Thirty one Pinot noir wines produced in 16 winegrowing regions in Europe (Germany, France and Switzerland), North America (USA), South America (Chile) and Oceania (Australia and New Zealand) were selected. A blind testing was performed on the wines by 14 judges; among which 9 were considered sufficiently repeatable (criteria evaluated from the sensory analysis results of two identical wines). Wines were described by 26 visual, olfacto…
