Full textThe objective of the present work was to study the impact of structural variations on the release of aroma compounds and on aroma perception. To achieve this purpose, three models of fresh cheeses were prepared. Nosespace experiments, which consist in the analysis by mass spectrometry of air expired from the nose during food consumption, showed that a higher quantity of aroma compounds was released from harder gels. The release of aroma compounds was also faster for these harder gels. Sensory profile of cheeses showed that the intensity of perceived aroma was lower for the harder gels. Therefore, we could not establish a link between aroma perception and in vivo aroma release parameters. The hypothesis of a cognitive interaction between texture and aroma perception was proposed to explain the impact of structural variations on aroma perception

Full textTexture and aroma are the two main apple quality characteristics. The aim of this work is based on the comprehension of the role of these properties on fruit quality perception during post-harvest period of storage, and to study their evolution during that period. The first part of this study made it possible to identify the biochemical markers of the texture evolution of apples, which are, the solubilization and the depolymerization of pectins. The second part of this work presents the development of a new extraction technique of apples aroma, named “artificial mouth”, as well as that of a validation tool of this prototype by a methodology of statistical analysis of the texture of image. In a last part, the odorous molecules of apples were identified using this artificial mouth. Among them, the odorous molecules responsible for apples aroma were also distinguished

Full textThis study deals with volatile molecules (oxygen, water vapour and especially aroma compounds) transfer into and through packaging (treated-papers and thermoplastic), in controlled storage conditions (temperature and relative humidity); aroma compounds are released by a solid food matrix (sponge cake). Different methods are compared between each others for the determination of the transfer parameters of aroma compounds through packaging. Volatile molecules transfer through packaging is essentially governed by their diffusion which decreases by compression of papers. Paper coating modifies their affinity for aroma compounds. The increase of storage temperature and relative humidity increases transfers and modify interactions between aroma compounds and treated-papers. Due to volatile molecules transfers through treated-papers, the odour and texture of the sponge cake are modified after storage

Full textThe main objective of this study was to understand the respective role of the structure of a food product and of the physicochemical interactions on flavour release. For that purpose, fruit preparations have been chosen as model matrices. In a first step, two complementary tools were used to characterise the structure of the model matrices: rheology and confocal laser scanning microscopy. To investigate flavour release, an instrumental approach has been favoured in order to study separately the kinetic phenomena that can occur during the release in different conditions. The thermodynamic and kinetic parameters have been used to interpret the release profiles obtained for the different aroma molecules in static and dynamic conditions

Full textAn addition of texture agent to the food matrices induces in general a decrease in the aroma perception. However, we know just a few about the mechanisms involved and it is not ensured. First, changing the nature and the concentration of the gelling agent and of the additional salts, a range of matrices differing by their rheoligical properties and textures was established. Secondly, aroma release and perception from two gels of different consistency were studied. From the kinetics of aroma release, partition and "apparent" mass transfer coefficients were determined. In a third time, the release curves were studied for matrices of differing physical states: a thickened solution and two gels with varying consistencies. The obtained differences allowed us to discuss the distinct effects of the addition of the polysaccharide, of its organization in tridimensionnal network and of the densification of this network

Full textA traditional French butter is obtained in churning ripened cream. However butter manufacture is mainly based in the NIZO process. For this reason we studied 16 butters with different geographic origins and fabrication processes in order to evidence the main molecules responsible for their aromatic diversity. A sensory cartography of butters was established with free choice profiling methodology. From a physio-chemical point of view a vacuum extraction procedure was optimized. We studied also the influence of the medium on volatility and odorous intensity of flavour molecules. Our results indicate that NIZO process leads to more intense cream notes, but less diversified products. Moreover the butter diversity is also due to their geographic origin

Full textWith the aim of producing of aromatic compounds « green notes », the fatty acid hydroperoxides are used as substrates for the yeast Yarrowia lipolytica which express the cloned hydroperoxide lyase of green bell pepper. This enzyme allows the transformation of hydroperoxides into C6 aldehydes, principal compounds of « green notes ». The presence of hydroperoxides in the culture medium exerts repercussions on the yeast by inhibiting the cell growth, inducing the fall of viability and fluidizing the cellular membrane. They also cause an oxidative stress on the yeast cell metabolism. The medium potential of oxydoreduction seems to have an influence on the impact of hydroperoxides on the yeast cells. The variation in the activity of antioxidant enzymes of the cells cultivated in the reducing medium (Eh -133 mV) is less important than that of the cells cultivated in the control medium (Eh +220 mV). Finally, a factorial design was applied to determine the factors supporting the hexanal production. They are mainly the hydroperoxide substrates and the reducing agent (dithiothreitol). The optimum conditions of bioconversion were thus determined: 119 mM of fatty acid hydroperoxides and 50 mM of dithiothreitol
