Role of human metabolizing enzymes in food perception

2022

Flavor is the main factor determining food acceptability. Flavor corresponds to the combination of the signals from the gustatory system, the olfactory system and the trigeminal system. Interactions between proteins and flavor molecules in oral/nasal cavities are proposed to modulate flavor perception through a series of events knowns as perireceptor events. Among these proteins involved in this modulation are found enzymes mainly known for their role in the detoxification process. These enzymes are able to recognize a large panel of molecules. We proposed to explore the role of these enzymes in food perception. We demonstrated that enzymatic activities present in the oral epithelium and sa…

How does taste influence food preferences and food intake in early childhood?

2012

Humans are born with very few flavor preference. The most consistent observations concern taste: newborns exhibit an early attraction for the sweet taste, in opposition to the avoidance of the bitter taste. Odor preferences are less obvious and are generally related to prenatal learning and/or have biological relevance (Schaal, 2006). The objectives of this presentation will be to describe the early taste preference, how they evolve in early infancy (Schwartz, Issanchou, & Nicklaus, 2009), and how the taste of the foods or the individual attraction toward tastes might influence food preference in infancy (Schwartz, Chabanet, Lange, Issanchou, & Nicklaus, 2011), as well as food intake in ear…

Piecing together the taste signaling puzzle

2010

International audience; The identification of the genes coding for bitter, umami, sweet and sour taste receptors has provided us with unique tools to investigate the gustatory system. As a consequence, tremendous progress towards our understanding of the functional organization of the peripheral taste system has been achieved over the past decade. In particular, key components of the taste receptors signaling cascades have been identified as well as populations of chemosensory cells in the olfactory, respiratory and digestive systems expressing taste receptors. Besides sharing receptors and signaling molecules (gustducin, phospholipase-C b2…) with taste bud cells, these cells display a simi…

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…
