Characterisation of the volatile fraction of aromatic caramel using heart-cutting multidimensional gas chromatography
2014
The first aim of our study was to improve characterisation of the volatile fraction of aromatic caramel by applying heart-cutting multidimensional gas chromatography coupled to mass spectrometry and olfactometry (MDGC-MS-O) on targeted odorant fractions. The second aim was to compare the volatile composition of two caramel samples, which differed in terms of their carbohydrate composition and cooking process. MDGC analyses enabled identification of 37 compounds (17 with the addition of pure standard) in the burnt sugar caramel, 20 of which were reported for the first time in caramel. Fifteen compounds were identified as odour-active and described using a range of attributes such as floral, …
Oral processing and matrix composition affect aroma release and particle size distribution after consumption of coffee-creamer emulsions.
2016
International audience; Context and objectives: In humans, the main events that contribute to in-mouth emulsion breakdown are shear forces due to tongue movements and action of saliva. To date, most of the studies on the field were conducted on model emulsions and little is known about creamer emulsion and in particular hot coffee/creamer emulsions. In this context, the objective of the present work is to better understand how human oral physiology may govern the in-mouth breakdown of coffee-creamer beverages with consequence of food bolus structure and aroma release and to focus on saliva role and composition in particular. Methodology: The work was conducted on 7 coffee-creamer matrices d…

Does oral health affect food comfortability and bolus properties during consumption of dairy products in elderly population?
2017
The elderly population is growing increasingly. In 2030, 1/3 of the population will be over 60 years old. However this population has specific nutritional needs and often, oral impairments such as loss of tooth and/or decrease of salivary flow. Therefore it is necessary to develop foods adapted for the elderly, in terms of organoleptic properties and nutritional composition. In this context, the purpose of this work is to study the impact of oral impairments of elderly persons on food comfortability and bolus properties during the consumption of dairy products.76 elderly persons (ages 66 to 88, 42 women and 34 men), with or without oral health problems in terms of dental and/or salivary sta…
