GC-olfactometry and odour recombination

GC-olfactometry and odour recombination. 16. international symposium on olfaction and electronic nose
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…
The odour of human milk: Its chemical variability and detection by newborns
2019
International audience; Human milk odour has for long elicited research interest with regard to its function in breastfeeding initiation. The present review aims to provide an overview of the behavioural effects of human milk odour in the human neonate, considering different types of response measures in a feeding or non-feeding context. Further, an overview of the current knowledge of odorant composition and factors influencing milk odour is provided by summarizing results from analytical studies using olfactometry, and addressing changes in milk odour due to storage, lactational stage, and maternal dietary intake of odorous substances. We finally highlight some issues for future research.
Nutritional quality of extra virgin olive oil determined by the application of a new functional matematic index
2015
The extra virgin olive oil is very important in the Mediterranean diet. From the nutritional point of view, the high energy content and an optimal ratio between saturated and unsaturated fatty acids, together with the presence of minor compounds such as phenols and tocopherols and the related antioxidant capacity, confer to this product a high healthy value.The extra-virgin oil’s nutritional properties depend on the pedoclimatic conditions, cultivar and the production process. In the last years many studies have been performed to remark and describe the safety and nutritional quality of the extra-virgin olive oils but it is difficult to compare different parameters representative of oil’s n…

Effects of school-based physical activity on mathematics performance in children: a systematic review
2019
AbstractBackgroundThe benefits of physical activity (PA) on children’s health and wellbeing are well established. However, the benefits of PA on academic performance and particularly on mathematics performance warrant systematic analysis. Mathematics is one of the core subjects in school education globally.MethodsWe systematically searched, analysed and synthesized the literature on the effects of school-based PA interventions on mathematics performance in children aged 4–16. A total of 29 studies consisting of randomised trials and other interventions with control groups were identified through a systematic search, and 11 of them provided sufficient data and appropriate design for a meta-a…
Organic food consumption: The relevance of the health attribute
2020
During the last decades, organic food products have become the main sustainable alternative to conventional food consumption. Among the several organic food attributes that consumers recognize in organic food, healthiness has been reported as the primary motivation to buy products certified as organic. The objective of the current study is to assess the relative weight of the health attribute among other recognized organic food attributes. To achieve this aim, a multiple price list (MPL) methodology is adopted to elicit consumers&rsquo
From beverage to companion food: Experts' principles for pairing wines and beers with food
2016
Projet "Associations entre bières et mets : de la perception au jugement des consommateurs en situation réelle de consommation".; Pairing beverages and dishes is part of culinary tradition. The objective is to identify the principles used by experts for pairing. Ten sommeliers and ten beer experts were presented with the description of a drink, either beer or wine. They were asked to suggest dishes to match the drink and explaining their choices. They performed the task with two beers and two wines. Both perceptual and conceptual principles are reported, the former being the most often used. Overall, 10 perceptual principles were identified. They intend to either reinforce the quality of th…
Energetic demands and nutritional strategies of elite cross-country skiers during Tour de Ski : A narrative review
2021
The Tour de Ski (TDS: 6–9 sprint and distance races across 9–11 days) represents the most intense competition series of the cross-country (XC) ski season and is characterized by accumulated stress from consecutive days of high-intensity (~ 85%–160% VO2max) racing, travel, cold temperatures and low to moderate altitude (500–1500 m above sea level). Here, nutritional strategies play a key supportive role for optimized health, recovery and performance. This narrative review aims to provide an evidence-based discussion on the energetic demands of the TDS and recommendations for nutritional strategies to optimize health and performance of XC skiers during and following the TDS. We highlight seve…
Evidence for Positive Selection in the Capsid Protein-Coding Region of the Foot-and-Mouth Disease Virus (FMDV) Subjected to Experimental Passage Regi…
2001
We present sequence data from two genomic regions of foot-and-mouth disease virus (FMDV) subjected to several experimental passage regimens. Maximum-likelihood estimates of the nonsynonymous-to-synonymous rate ratio parameter (dN/dS) suggested the action of positive selection on some antigenic sites of the FMDV capsid during some experimental passages. These antigenic sites showed an accumulation of convergent amino acid replacements during massive serial cytolytic passages and also in persistent infections of FMDV in cell culture. This accumulation was most significant at the antigenic site A (the G-H loop of capsid VP1), which includes an Arg-Gly-Asp (RGD) cellular recognition motif. Our …
