Chemosensory reactivity and food neophobia in preschool children: impact of smell, but not of taste

2014

Context and objective: Recent studies suggested that sensory sensitivity could be linked to food neophobia, described as the reluctance to eat, or the avoidance of, new foods. The objective of the present study was twofold. Firstly, this study aimed at assessing the links between smell reactivity and taste reactivity in children. Secondly, this study assessed the links between children’s smell/taste reactivity and food neophobia. The hypothesis was that the higher the chemosensory reactivity of the child, the more the child is neophobic. Method: One hundred and three dyads of mother-child, from the Opaline cohort, were involved. The child’s food neophobia was assessed using a validated pare…

Smell but not taste reactivity is related to food neophobia in toddlers: results from the Opaline cohort

2014

National audience; Context and objective: Research has previously identified relationships between chemosensory reactivity and food neophobia in toddlers. However, most studies have addressed this question using declarative data, and without analyzing separately smell and taste. The objective of the present study was twofold. The first objective was to assess the relationships between olfactory reactivity and taste reactivity in toddlers, using experimental designs with different tastants and odorants. The second objective was to determine the relationships between olfactory /taste reactivity and food neophobia in toddlers. The hypothesis was that the higher the chemosensory reactivity of t…

Saliva in Food … How does it drive sensory perception?

2014

Saliva is a highly complex body fluid composed of many proteins, peptides, small organic molecules and ions. Saliva is produced and secreted by major and minor salivary glands to protect the mouth and to participate to the digestion. Generally distinction is made between resting saliva that is a result of autonomic stimulation, and stimulated saliva that is produced during chewing and taste stimulation. The link between saliva and sensory perception can be thus regarded through two main angles: the role of resting saliva as a background taste and the mechanistic role of saliva during eating. Indeed resting saliva (and its components) is continuously bathing our oral cavity and as such stimu…

The sweet taste receptor is a heterodimer composed of two subunits called T1R2 and T1R3. Each subunit belongs to the class C of G protein-coupled receptors and is constituted by a large extracellular N-terminal domain (NTD) linked to the transmembrane domain by a cysteine-rich region. It has been shown that T1R2 and T1R3 NTDs are both able to bind natural sugars and sucralose with distinct affinities and undergo ligand-dependent conformational change (Nie et al., Curr Biol, 2005). However, the binding properties of T1R3 NTD and the relative contribution of the two subunits to the heterodimeric receptor function remained largely unknown. To characterize the binding properties of each subunit…

T@sty: a test for assessing taste sensitivity. Description, application example

2019

The aim of the poster is to present the T@styTM device and to give an example application through results obtained in an ongoing study. The advantages and limits of this device will be discussed. T@styTM device, usable for home testing, was designed to assess human ability to detect several tastants at low concentrations in order to provide individual profiles based on sensitivity to the five tastes (sweet, salty, sour, bitter, and umami). Three test-sheets made of edible paper are used for each taste (three replicate measurements). Each test-sheet consists of six series of three precut discs (one “tasty disc” and two neutral discs) on which taste stimuli of different intensities were depos…

Flavour & saliva interaction – a brief overview

2015

Saliva is a highly complex body fluid composed of many proteins, peptides, small organic molecules and ions. Saliva is secreted at rest and during eating by major and minor salivary glands. Resting saliva is continuously bathing our oral cavity and as such stimulates our taste receptors playing thus a role in taste sensitivity against some active taste substances. Beside, during eating, foods are chewed and a significant level of stimulated saliva is rapidly incorporated in the bolus. This in-mouth phenomena impact on flavor release and thus perception through saliva-food physical interactions but also through the action of biological compounds (enzymes mainly) against the food matrix. Sali…
