Is the improvement of the nutritional quality compatible with the maintenance of the sensory quality? : the example of biscuits

2013

French biscuit producers are willing to improve the nutritional composition of their products. The. objective of this work was to determine whether it was possible while maintaining the sensory. quality of the reduced product. The first study dealt with the impact of fat and sugar reduction on liking and sensory perception of. 9 types of biscuits and cakes. Results show that children perceived almost no difference and liked. equally the standard and the fat- and/or sugar-reduced variants for most types of biscuits. For. products reduced without adding polyols, adults less like fat- or sugar-reduced variants than. standard ones mainly when they were perceived as less sweet, and to a lesser e…

A study on texture-taste-aroma interactions: physico-chemical and cognitive mechanisms

2009

International audience; Texture–taste, texture–aroma and aroma–taste interactions were examined in custard desserts varying in viscosity (at identical composition), sucrose level and aroma nature. All reciprocal interactions were investigated, with each binary interaction addressed through an independent sensory study. Rheological, in vivo aroma release and sucrose release measurements were run in parallel to control for a possible physico-chemical origin of these interactions. Observed interactions were found to be dependent upon the nature of the sensory modalities involved; physico-chemical mechanisms could only in some instances entirely explain these interactions. Taste and aroma did n…

« Messicoles » : conservation des plantes messicoles dans les parcelles cultivées : caractérisation des systèmes de cultures favorables, rôles foncti…

2013

Segetal plants, or “messicoles” as they are known in French, are weedy inhabitants of wheat crops (mainly winter cereals). The national list of segetal species includes 102 taxa; of which 7 are extinct, 52 threatened, 30 to be kept under close observation and 12 abundant. Data on their distribution indicates that they are mostly in decline. As their survival is intrinsically linked to farming systems, we need to improve knowledge on their relationships with land management in order to establish a sound scientific basis for protection tools, to support and guide farmer conservation measures and to disseminate concerns for segetal biodiversity to agro-environmental policymakers. We propose to…

Logique managériale et secteur éducatif. De la perception subjective par les professionnels à la création d'indicateurs ?

2017

International audience; Peu de recherches se sont employées à caractériser les changements profonds qui s'opèrent dans la profession enseignante sous l'effet de l'adoption de principes issus de la logique managériale. L'objectif de notre communication consistera à tenter d'identifier les déterminants qui impactent directement la profession et les professionnels de terrain, à travers un recueil subjectif portant sur les nouveaux organisateurs managériaux auxquels ils sont confrontés. Les données recueillies, issues d'une recherche encore en cours, proviennent d'un sondage réalisé auprès de 21 642 enseignants du premier degré. Le choix d'un aperçu subjectif (même si ce dernier sera a posterio…

Inclusive education for pupils with disabilities in France : what do teachers say ?

2019

International audience; Inclusive education implies changes and upheavals in both the teaching practices and the school organization as a whole. Inclusive education implies a paradigm shift where the conditions for success are based on the ability of the school to adapt to the diversity of the public it serves (Dyson et al., 1999, Plaisance et al., 2007). Therefore the current situation leads us to reflect on the arrangements defined and put in place to accommodate and support pupils with disabilities in their schooling in France (since the 2005 law). The aim of the research is to evaluate the quality of school devices. Our research concerns a population of 68 French teachers.
