Inter-individual retronasal aroma release variability during cheese consumption: Role of food oral processing

2014

The aim of our study was to explain inter-individual differences on in vivo aroma release during cheese consumption by oral physiological parameters. To reach this objective, 34 subjects were recruited. Their salivary flow, oral volume and velum opening were determined. Six cheddar-based melted cheeses with different fat levels and firmness were flavoured with nonan-2-one.(NO) and ethyl propanoate (EP). During their consumption (free protocol), in vivo retro nasal aroma release was followed by Atmospheric Pressure Chemical lonisation-Mass Spectrometry (APCI-MS). Chewing activity was evaluated by electromyography recordings. Bolus saliva content, mouth-coating, and bolus rheology were also d…

Main individual and product characteristics influencing in-mouth flavour release during eating masticated food products with different textures: mech…

2013

Research Areas: Life Sciences & Biomedicine - Other Topics; Mathematical & Computational Biology; A mechanistic model predicting flavour release during oral processing of masticated foods was developed. The description of main physiological steps (product mastication and swallowing) and physical mechanisms (mass transfer, product breakdown and dissolution) occurring while eating allowed satisfactory simulation of in vivo release profiles of ethyl propanoate and 2-nonanone, measured by Atmospheric Pressure Chemical Ionization Mass Spectrometry on ten representative subjects during the consumption of four cheeses with different textures. Model sensitivity analysis showed that the main paramet…

Food composition and oral processing influencing flavour release and perception

2013

Aroma and taste release depend on food composition and texture Oral physiology influences aroma and taste release and perception (interindividual variability) Aroma and taste release does not always explain aroma and taste perception Aroma-taste cross modal interactions may explain these differences Aroma-taste cross modal interactions can also be used in a strategy of salt reduction.

Flavour release and perception

2012

Flavour perception is a complex combination of the olfactory, gustatory and trigeminal sensations perceived during eating. During this eating process, tastants must be dissolved into saliva to be transported to the taste bud receptor cell membranes and aroma compounds have to be released in the oral cavity then transferred to the nasal cavity to reach the olfactory receptors. This release highly depends on food composition and structure, on the molecular properties of the stimuli but also on physiological characteristics of individuals and mastication behaviour. However, interactions occur between texture, taste and aroma perception at different levels: physic-chemical interactions in the f…

Développement de l'acceptabilité des aliments solides. A partir de quel âge les morceaux sont-ils acceptés par l'enfant sain ?

2019

Les aliments solides sont proposés aux nourrissons vers 4-6 mois, lorsque leurs besoins nutritionnels ne peuvent plus être uniquement assurés par le lait. Ces aliments (fruits, légumes, produits céréaliers…) sont généralement proposés sous forme de purée ou de bouillie. Au fil des mois, les purées sont ensuite remplacées par des textures de plus en plus consistantes et dures, permettant à l'enfant d'apprendre progressivement à manger les aliments de la table familiale. Cet apprentissage est dépendant du développement des capacités masticatoires de l'enfant, particulièrement dynamique dans la petite enfance. En effet, pour accepter un aliment, l'enfant doit être capable de le manger. Si, à l…
