Can we Trust Untargeted Metabolomics: Results of the Metabo-ring Initiative, a Large-scale Multi-instruments Inter-laboratoire Study

2013

This work was presented at the 6th Journée Scientifique du Réseau Français de Métabolomique et Fluxomique, Nantes, May 2012 and at the 8th International Conference of the Metabolomics Society, Washington, June 2012This work was presented at the 6th Journée Scientifique du Réseau Français de Métabolomique et Fluxomique, Nantes, May 2012 and at the 8th International Conference of the Metabolomics Society, Washington, June 2012; The metabo-ring initiative brought together five nuclear magnetic resonance instruments (NMR) and 11different mass spectrometers with the objective of assessing the reliability of untargeted metabolomics approaches in obtaining comparable metabolomics profiles.

Effect of environmental labelling on food choices: A randomised controlled trial in a virtual supermarket

2022

Gros plan sur ChemoSens, R&D et expertise en analyses physico-chimique et sensorielle. Une plate-forme du Centre des Sciences du Goût et de l'Aliment…

2016

ChemoSens est une plate-forme de recherche publique du Centre des Sciences du Goût et de l'Alimentation (CSGA, unité mixte de recherche CNRS - INRA - Université Bourgogne Franche-Comté). Son originalité repose sur l'utilisation combinée de la chimie et de l'analyse sensorielle pour développer de nouvelles approches de caractérisation des aliments et du comportement alimentaire.

Changes in properties of palm sugar syrup produced by an open pan and a vacuum evaporator during storage

2013

International audience; The aim of this study was to monitor the changes in the properties of palm sugar syrup produced by an open pan and a vacuum evaporator at 70°C and 80°C during storage under 4°C and room temperature (30°C) for 12 months at monthly intervals. During storage, Maillard reaction took place in samples stored under 4°C lower than those stored under 30°C. This was shown by lower a* values, intermediate browning products (IBP), browning intensity (BI) and HMF content, and higher L* values, fructose, glucose and free amino group contents during storage for 12 months. HMF, a possible mutagen formed by nonenzymatic browning during the heating and storage of sugar based products,…

Effect of extrusion on the anti-nutritional factors of food products: An overview

2017

International audience; Edible plant seeds such as cereals, legumes and nuts contain substantial amounts of nutrients including proteins, carbohydrates, minerals, vitamins, and dietary fibers. However, the bioavailability of these nutrients in humans or animals is relatively low, particularly when they are consumed in their unprocessed or raw form. One of the major factors that contribute to a lower nutritional value of legumes and cereals is the presence of naturally-occurring anti-nutritional factors (ANFs, e.g. phytate, tannins and enzyme inhibitors) that indirectly decreasing the bioavailability status of minerals. Fortunately, these ANFs can be modified or reduced through different pro…

Division of labor in anti-parasite defense strategies in ant colonies

2014

Division of labor is a key characteristic of social insects and contributes to their ecological success. Especially in disease defense, the intra-colony partitioning of sanitary work can reduce disease transmission, keep nestmates available for other tasks and reduce costs associated with sanitary task performance (i.e. at the behavioral and physiological level). Factors internal and external to the individual affecting sanitary task allocation are not well known and most studies investigated genetic differences between workers performing behavioral sanitary work. In the first two studies I addressed whether individual experience (through repeated exposure to a sanitary hazard or performanc…

Analysis of fluorescent MRI contrast agent behavior in the liver and thoracic aorta of mice.

2004

To characterize the behavior of magnetofluorescent products injected in mice intravenously.The magnetic resonance imaging (MRI) products were labelled with fluorescent molecules to examine the biodistribution process in vivo and observe them at the cellular level by means of confocal microscopy. Three-dimensional (3D) sequences of images were obtained by spectral analysis of sample preparations in a multiphoton confocal microscope and analyzed by the factor analysis of medical image sequence algorithm, which provides factor curves. Factor images are the result of image-processing methods that utilize information from emission spectra. Preparations are also screened in the counting mode to p…
