(PL6) From eating to liking: Saliva, the missing link
2012
abstract of plenary talk; During the experience of eating, saliva is the first fluid meeting the food introduced into the mouth. During mastication, saliva and food interact strongly and mix together to form the bolus. The contribution. of saliva to the final volume of the bolus can even be higher than the volume of the food itself. It is. therefore not the food itself that is perceived when consumed but the mixture of food and saliva. However, the role of saliva in perception is not totally elucidated yet. Saliva plays various roles in food perception. First of all, it allows the release of taste and aroma. compounds from the food matrix in the oral cavity. Availability of these compounds …

Osmotic stress affects the stability of freeze-dried Lactobacillus buchneri R1102 as a result of intracellular betaine accumulation and membrane char…
2014
Aims To help cells to better resist the stressful conditions associated with the freeze-drying process during starter production, we investigated the effect of various osmotic conditions on growth, survival and acidification activity of Lactobacillus buchneri R1102, after freeze-drying and during storage for 3 months at 25°C. Methods and Results High survival rates during freeze-drying, but not during storage, were obtained when 0·1 mol l−1 KCl was added at the beginning of fermentation, without any change in membrane properties and betaine accumulation. This condition made it possible to maintain a high acidification rate throughout the process. In contrast, the addition of 0·6 mol l−1 KCl…
Current and New Insights on Molecular Methods to Identify Microbial Growth in Fruit Juices
2018
International audience; Identification of microorganisms in fruit juices plays an important role as it determines the viability of this food product from a commercial point of view. Several microorganisms use fruit as a substrate, thus causing spoilage and generating off‐flavors and odors. In addition, under favorable conditions, toxigenic fungi can produce mycotoxins in fruit juices. Conventional detection and enumeration of microorganisms using traditional plating assays are accurate and can detect low microbial contamination levels. However, in most cases they require long detection times. In recent years, the food industry has shown increased interest in developing new methods with incr…
Emerging opportunities for the effective valorization of wastes and by-products generated during olive oil production process: Non-conventional metho…
2015
Abstract Background A large amount of wastes and by-products are generated during olive oil production process. Traditionally, these products have been considered as a problem. However, they constitute a great source of high-added value compounds, which have the potential to be used as food additives and/or nutraceuticals. Therefore, valorization of wastes and by-products from food industry kills two birds with one stone and addresses both the use of waste and by-products and societal health, thus greatly contributing for a sustainable food chain from an environmental and economical point of view. Scope and approach In the present review, current and new insights in the recovery of high-add…
[Norovirus infections: an overview]
2010
National audience; Noroviruses belong to the Caliciviridae family. They are a major cause of sporadic cases and outbreaks of gastroenteritis in all age groups, and are responsible for a considerable disease burden in industrialized countries. Noroviruses are single-stranded RNA viruses, and show great genetic diversity making their detection difficult. Noroviruses can be divided into 5 genogroups, which themselves are subdivided into genotypes. Besides chance mutations that occur during viral replication, the great heterogeneity observed among noroviruses is also due to intra and inter-genotypic recombination events between strains. Some of these new variants or new recombinants are frequen…
Les comportements préalables à la prise lactée chez le souriceau : caractérisation de sécrétions maternelles réactogènes et implication de l'expérien…
2012
Birth is one of the most delicate periods mammalian infants have to deal with. Newborns have then to adapt physiologically and behaviorally to the aerial environment, and one of their first challenges is to ingest colostrum and milk. It is paradoxical that the survival of pups is conditioned by the success of this first suckling, and that we have so little understanding of the stimuli that underlie and promote it. Thus, the present work aims to contribute to answer how immature and naïve newborns do manage to orient to a nipple, to grasp it, and to suckle efficiently? This general issue will be addressed in the mouse in focusing on: i) the nature of the chemical substrates that newborn mice…
Fast detection of bovine milk in Rocquefort cheese with phastsystem by gel isoelectric focusing and immunoblotting
1992
.Summary - A fast procedure for the detection of bovine milk in Roquefort cheese is described. It is based on the separation by rapid isoelectric focusing on Phasteysterne apparatus of 12-caseinsfrom the milk of the 2 species. The presence of bovine milk is also confirmed by the detection in the electrophoretic pattern of a ~-casein derived peptide from bovine milk, during cheese ripening, identified by immunoblotting. By using Ihis procedure, levels of bovine milk as low as 5% were easily delecled in Roquefort cheese ripened for a period varying from 10 days to 5 months.
