Renforcement de la saveur sucrée par ajout d'arôme dans des boissons
2018
Pour répondre aux recommandations des pouvoirs publics de réduire la consommation de sel, de sucre et de matières grasses qui entrent dans la composition des aliments, les industriels doivent reformuler leurs produits tout en maintenant une bonne acceptabilité pour le consommateur. La perception globale d'une flaveur résulte le plus souvent de l'intégration d'informations transmises par différents sens. Cette intégration est le support d'interactions dites multimodales entre différentes modalités sensorielles. sCes interactions sont principalement dues à des associations apprises mais peuvent être utilisées comme stratégies alternatives pour la reformulation d'aliments à teneur réduite en s…
Interactions arôme saveur texture
2012
L’acceptabilité des aliments par le consommateur dépend, en partie, de leurs propriétés sensorielles. La perception de l’arôme et de la saveur est principalement liée à la présence de molécules odorantes ou sapides. Néanmoins la perception de l’arôme peut être modifiée par la présence de certaines saveurs et réciproquement, par l’existence d’interactions perceptives. De même la texture de l’aliment va influencer la perception de son arôme et de sa saveur, principalement par l’existence d’interactions physicochimiques entre les molécules au sein de l’aliment ou par des modifications de la libération des molécules odorantes et sapides lors de la mastication. De ce fait, faire varier l’une de …
Ces molécules qui éveillent nos papilles
2017
The sense of taste is a chemical sense and one of the most ancestral sensory modalities. It allows detectingand appreciating taste molecules present in our food. Beyond our vital needs, the pleasure elicited from whatwe eat can drive our feeding behaviors sometimes up to excess. Food intake involves several sensorysystems, mainly smell and taste. The underlying molecular mechanisms are relatively complex. This articlefocuses on the extent of the chemical space associated with the five primary tastes (sour, salty, sweet, bitterand umami), and details the fundamental role of gustatory receptors in the perception of taste as well aswithin interindividual variabilities.

Livelli e fattori della produttività scientifica della psicologia accademica. Una analisi bibliometrica
2015
The survey concerns the bibliometric analysis of the scientific productivity of the 8 Scientific Areas in which the Academic Italian System of Psychology is subdivided (Settori Scientifico-Disciplinari, SSD). To this end, data were retrieved from the Scopus (available at March 2012), one of the most internationally representative scientific databases. Results shows that the Scientific Areas differ from each other with respect to productivity but they tend to show similar rates of growth. Moreover, the Scientific Areas show different organizational characteristics (extension of the collaborative networks, language of publication, number of the international co-authorships); these characteris…
BEMOD: A DSGE Model for the Spanish Economy and the Rest of the Euro Area
2006
In this paper we present the theoretical foundations and the simulation results obtained with a new dynamic general equilibrium model developed at the Banco de España for the Spanish economy and the rest of Euro area. The model is designed to help in simulating the effect of alternative shocks on the main aggregate variables. The main contributions of this work from a theoretical perspective are the modelling of a monetary union composed of two regions, the inclusion of housing as a durable good with its own sector of production and the degree and detail of the disaggregation considered for each country in the model, which replicates the Quarterly National Accounts. On the empirical side, t…
Are Public Subsidies to Encourage Young Farmers Effective? Case Study of a First-Time Farm Set Up by a Young Female Farmer in the Valencian Region of…
2021
Generational renewal and the incorporation of women into the rural world are fundamental for the sustainability and modernisation of the agricultural sector. Hence the special government protection granted to the sector, which appears in both European legislation on rural issues and in the global strategy of the 2030 Agenda and the Sustainable Rural Development Goals involving a commitment to measures aimed at helping young farmers to set up agricultural holdings and especially at encouraging women to engage in farm management. In the case of Spain, this is nothing new, given that Law 35/2011 on the Shared Ownership of Agricultural Holdings became a veritable revolution in terms of gender i…

Síntesis de biodiésel y caracterización de bebidas alcohólicas mediante técnicas de elevada resolución
2015
En esta Tesis Doctoral se describe el desarrollo de procedimientos de síntesis de biodiésel y caracterización de bebidas alcohólicas mediante técnicas analíticas de elevada resolución. La puesta a punto de los procedimientos de síntesis de biodiésel y sus estudios de caracterización se realizó en respuesta a la demanda de producción de biocombustibles basados en materias primas renovables y de bajo impacto ambiental que puedan reemplazar de manera efectiva al diésel convencional obtenido a partir de fuentes fósiles. Otro de los aspectos descritos en esta Tesis, y entroncando con una de las líneas actuales de investigación del grupo, es la caracterización de proteínas en diversos extractos v…
The use of very high resolution images for studying Posidonia oceanica reefs
2020
Posidonia oceanica is an endemic Mediterranean seagrass that forms wide and dense meadows from the surface up to about 40 m depth. This species can develop a biogenic structure called matte, a typical terraced formation built up by itself, consisting of intertwined rhizomes, roots and sediment, which may allow shoots to reach the sea surface forming reefs (récif barrière), considered natural monuments. Posidonia oceanica reefs are particularly exposed to the ongoing increase in temperature and in storm frequency and intensity due to climate change, with negative repercussions on their conservation. Much more attention must be paid to the implementation of monitoring tools able to detect ear…
