La diversité de consommation de fromages dans la petite enfance : un facteur protecteur des maladies allergiques ?

2015

Introduction Une diversité alimentaire importante et précoce a été montrée protectrice vis à vis des maladies allergiques (Roduit C. et al, JACI 2012 Jul;130(1):130-6). L'effet de la diversité de consommation de fromages, riches en microorganismes, n'a pas été étudié. Or l'exposition aux microorganismes est suspectée pour son rôle protecteur sur la survenue de maladies allergiques. Le but de notre étude était d'évaluer l'effet protecteur de la diversité de consommation de fromages vis-à-vis de maladies allergiques (MA) : allergie alimentaire (AA), dermatite atopique (DA), asthme (AS), rhinite allergique (RA) et bronchite (BR). Méthodes L'étude a porté sur 941 enfants de la cohorte PATURE (P…

Flavour release and sensory pereption in cheeses

2013

During the eating of food, the in-mouth process leads to food breakdown which induces the release of flavour compounds. Volatile and non-volatile compounds are released into the saliva, and volatile compounds are transferred into the vapour phase to reach olfactory receptors in the nasal cavity. The aim of this chapter is to review the effects of changing the composition of cheeses on the mobility, release and perception of flavour molecules (salt, aroma compounds), and to discuss the results with respect to human physiology. Cheese is a good model because it is possible to vary its composition (in lipids, proteins, salt), in order to comply with nutritional guidelines (less salt, less fat)…

L'intégration multisensorielle comme stratégie pour compenser la réduction en sodium et matière grasse dans les aliments

2015

In recent years;health authorities worldwide advise for a reduction of salt and fat in daily food consumption. However;foods with reduced salt and fat content are often not appreciated by consumers;Therefore;the formulation of low-salt-fat foods that maintain acceptability is a major concern in food research. In this thesis;the multi-sensory integration and release kinetics of flavor compounds were explored as strategies to compensate for salt and fat reduction in cheese products (model cheeses and real cheeses). The objective was to better understand the mechanisms leading to aroma and salt release during mastication and to evaluate how the matrix composition and structure influence salt a…

Relationship between sensory profiles and odor-active compounds detected by Gas-Chromatography olfactometry

2011

Cheese flavour has been widely studied and key-aroma compounds identified. However the strategies involved were mostly correlation studies between quantitative measurements of aroma compounds and either gas chromatography olfactometry (GC-O) data or sensory data. These correlations do not take in account the differences in the Stevens’ slopes relating sensory perception and concentration and perception thresholds. The objective of this study was thus to explain sensory perception of cheese by the intensity of single molecules measured by GC-O analysis. Seven commercial semi-hard cheeses were evaluated by a sensory descriptive analysis. Thirteen odour attributes were evaluated by a panel of …

Sodium ions models cheeses at molecular and macroscopic levels

2009

National audience; The excessive consumption of sodium is one of the causes of nutritional related-health problems. The reduction of salt content without affecting technological and sensorial properties of foodstuffs is currently a challenge for the food industry1. There is a need to develop tools to quantify the “active” sodium ions in food products at molecular and macroscopic levels to better understand in-mouth salt release and flavour perception. In this context, methods for the quantification of the bound fraction were developed: 23Na NMR single-quantum (SQ) and double-quantum-filtered (DQF) sequences at molecular level using Bruker Avance-500 spectrometer equipped with 10 mm probe 2,…
