La prise en compte de l’olfaction dans les sciences cognitives et les neurosciences a notamment permis de s’intéresser aussi aux dysfonctionnements de ce sens et d’examiner certains phénomènes linguistiques (inadéquation entre langage et odorat) ou littéraires (la mémoire proustienne). Neurologie et anthropologie semblent en arriver à la même conclusion sur l’inadéquation universelle entre le langage humain et les odeurs, à l’opposé de la relation entre langage et couleurs.

Abstract:
L’odorat, sens pendant longtemps sous-estimé chez l’homme, a été mis sur le devant de la scène par sa soudaine disparition, survenue pendant la pandémie de Covid-19, dont l’anosmie est un des symptômes majeurs. Pourtant, depuis longtemps, les virus respiratoires ont été associés aux troubles de l’odorat, dont 25 % seraient liés à une infection virale. L’olfaction débute dans le nez, au sein d’un épithélium olfactif qui a la particularité de contenir des neurones en contact direct avec l’environnement. Plusieurs virus respiratoires sont connus pour leur capacité réplicative au sein de cet épithélium. C’est notamment le cas du virus de la grippe (influenza) et du virus de la bronchiolite (VRS, pour virus respiratoire syncytial), mais leur tropisme pour ce tissu est bien moindre que celui du SARS-CoV-2. La physiopathologie de ce virus dans la cavité nasale a permis de commencer à comprendre les liens existant entre une infection virale et les troubles de l’olfaction.

Abstract:
La présence des sens interdits – odorat, toucher et goût – dans Florimont, qu’il s’agisse de la mise en prose bourguignonne ou de l’imprimé de 1529 d’Olivier Arnoullet, se révèle très limitée. L’imprimé offre davantage de termes mais se signale aussi par un manque d’intérêt pour des descriptions qui nécessiteraient l’emploi d’adjectifs ou d’adverbes précis et nombreux. La mise en prose fait surtout de certains des sens, notamment du toucher, les signes d’un rituel social et leur donne dans le récit un rôle fonctionnel plus que véritablement sensoriel. S’ils ne sont donc pas « interdits » – nos textes ne font place à aucun jugement moral –, ces sens, comme dans une certaine mesure les sens plus élevés de l’ouïe et de la vue, sont essentiellement présents pour faire avancer et nourrir l’action.

Abstract:
L'existence de troubles olfactifs, chez des patients alzheimer, a ete demontree par de nombreux auteurs. Les etudes anatomopathologiques ont confirme la presence d'une concentration importante des lesions caracteristiques dans les structures olfactives, structures etroitement reliees au systeme limbique. Ainsi une hypothese etiologique olfactive a ete proposee: des agents exotoxiques emprunteraient les voies olfactives peripheriques pour atteindre le systeme nerveux central. Les deficits olfactifs qui en decouleraient seraient, ainsi des marqueurs precoces de la maladie d'alzheimer. Quoi qu'il en soit de la validite de cette hypothese, les donnees concernant d'eventuels troubles olfactifs meritaient d'etre etudiees de facon plus approfondie. Il convenait d'analyser la specificite etiologique de ces troubles mais aussi la specificite de l'atteinte olfactive par rapport aux autres modalites sensorielles. Nous avons examine des patients souffrant de la maladie d'alzheimer, des patients souffrant d'autres types de demence et des sujets controles. Nous avons utilise des tests de reconnaissance et d'identification olfactives mais aussi visuelles. Outre cette etude transversale, nous avons effectue le suivi longitudinal de 4 patients alzheimer pendant 2 ans. Nous avons montre que les deficits olfactifs des patients presentant une demence severe ou moderee sont majeurs et identiques dans chaque groupe. Une deterioration en modalite visuelle est egalement enregistree. Les deficits olfactifs ne sont donc pas specifiques pour un meme groupe par rapport aux autres modalites sensorielles, et non specifiques des patients alzheimer par rapport aux patients souffrant d'autres demences. Par contre, lorsque les comparaisons sont effectuees entre des sujets dements presentant une demence legere, une specificite des deficits olfactifs par rapport aux visuels apparait nettement. De plus, tandis que le trouble de reconnaissance olfactive semble marquer la demence, quelle qu'elle soit, le trouble d'identification olfactive semble plus specifique des patients alzheimer. Les contre-performances enregistrees en identification olfactive pourraient etre ainsi des marqueurs precoces de la maladie d'alzheimer

Abstract:
Le bulbe olfactif (BO) représente dans le cerveau le premier relai dans le traitement des informations olfactives. Au niveau de cette structure, plusieurs types de neurones sont impliqués dans la modulation de l’information odorante, avant même que celle-ci ne soit envoyée vers des structures corticales supérieures. Parmi eux se trouvent les cellules granulaires (CGs), une population d’interneurones régulant de manière importante l’activité des cellules principales du BO. De manière intéressante, le BO est capable à l’âge adulte de produire et régénérer une partie de sa population interneuronale via le processus de neurogénèse adulte. Il est ainsi possible de faire la distinction entre les CGs générées au cours de la période postnatale (CGs postnatales) des CGs générées à l’âge adulte (CGs nouvellement générées). Le rôle que jouent ces CGs dans le traitement olfactif mais aussi dans les différents comportements olfactifs a pendant très longtemps donné lieu à des interprétations contradictoires. Le manque de cohérence au niveau des données peut s’expliquer par le fait que pendant longtemps, les CGs ont été considérées comme étant une population homogène de cellules. Néanmoins, des études ont montré que les CGs peuvent exprimer différents marqueurs neurochimiques. Notamment, nous nous sommes intéressés dans le cadre de notre étude à deux de ces marqueurs : la protéine kinase calcium calmoduline dépendante IIα (CaMKIIα) et la Calrétinine (CR). Une telle hétérogénéité au sein des cellules interneuronales du BO pourrait également refléter une hétérogénéité fonctionnelle, chaque sous-population de CGs pouvant contribuer de façon propre et unique au traitement des informations olfactives et donc au comportement olfactif. Dans la première partie de ces travaux, nous avons étudié le rôle fonctionnel des cellules exprimant la CaMKIIα et l’avons comparé à la population générale de CGs. De manière intéressante, nous montrons que, bien que ces deux populations de cellules soient en tous points semblables au niveau morphologique, les cellules CaMKIIα reçoivent un niveau d’inhibition moindre par rapport à leurs homologies négatives, les rendant plus susceptibles d’être activées suite à des tâches comportementales spécifiques. De plus, l’inhibition spécifique des cellules CaMKIIα- positive entraine une perturbation des performances de discrimination fine. Dans la seconde partie de ces travaux, nous nous sommes intéressés cette foisci à la sous-population de CGs exprimant la CR, en tenant compte également de la période développementale de ces cellules (i.e CGs post-natales ou nouvellement générées). Nous montrons que les cellules nouvellement générées exprimant ou non la CR, ainsi que les cellules CR-positives postnatales diffèrent quant à leurs propriétés électrophysiologiques. De plus, tout comme les cellules exprimant la CaMKIIα, les cellules exprimant la CR présentent un niveau d’activation plus important à la suite de certaines tâches comportementales et sont également nécessaires à la bonne réalisation de tâches de discrimination olfactive.

The olfactory bulb (OB) is considered as the first relay in the brain during olfactory processing. Several types of neurons are involved at the level of this structure in the refinement of the olfactory information before it is sent to higher cortical structures. Among the cell types involved is the population of granule cells (GC), a population of interneurons largely regulating the activity of OB principal cells. Interestingly, the OB retain during adulthood the ability to produce and renew part of its interneuronal pool through a process called adult neurogenesis. Therefore, it is possible to distinguish in the adult OB between GCs born during the early postnatal period (early-born GCs) to the one that were generated during adulthood (adult-born GCs). Several studies aimed at determining the precise role played by GC in olfactory processing and olfactory behavior, giving rise quite often to conflicting results. This absence of coherence in the data could come from the fact that for long, the population of GCs was considered as a homogeneous cell population. However, GCs were shown to express diverse neurochemical markers. In this study we investigated more particularly into two of those markers, showed to be expressed by GCs: the Ca2+/calmodulin-dependent protein kinase IIα (CaMKIIα) and Calretinin (CR). Hence, such a heterogeneity in the phenotype of OB interneurons could also underlie a functional heterogeneity of the different GC subpopulation, each one contributing in a unique way to olfactory processing and thus olfactory behavior. In the first part of this work, we investigated the functional role of CaMKIIα- expressing cells and compared it to the general population of GCs. Interestingly we revealed that CaMKIIα-positive GCs are more prone to activation following specific behavioral tasks, likely due to a decreased level of inhibition as compared to their negative counterparts. Moreover, the specific inhibition of this GC subpopulation let to alteration of animals’ fine discrimination abilities. In the second part of our work, when focusing this time on the subpopulation of CR-expressing GCs, taking this time also into account the developmental period at which they were generated (i.e early- versus adult-born cells), we showed that adultborn CR-expressing and non-expressing GCs, but also early-born CR-expressing GCs display different electrophysiological characteristics. Moreover, as for CaMKIIα- positive GCs, CR-positive GCs present a higher level of activation following specific olfactory tasks and are also important for a proper ability to perform olfactory discrimination tasks.

Abstract:
L'objectif du travail de thèse était de mieux comprendre l'effet de l'expérience culturelle sur les mécanismes cognitifs de catégorisation des odeurs. Une étude interculturelle, menée auprès d'étudiants américains, français et vietnamiens, montre, dans une première partie, que les représentations mentales des odeurs seraient formées davantage sur la base de la fonction associée aux odeurs dans une culture donnée plutôt que sur des propriétés perceptives universelles. Une deuxième partie, s'inspirant de travaux sur d'autres catégories cognitives, indique que les catégories olfactives semblent être organisées selon un gradient de typicalité et que cette structure interne serait déterminée par des facteurs perceptifs comme la saillance. Ainsi, de part leur saillance, certaines odeurs joueraient le rôle de points d'ancrage universels dans l'organisation des catégories olfactives et d'autres, de part leur valeur culturelle, seraient les points d'ancrage spécifiques à une culture donnée
The aim of this dissertation work was to better understand the effect of cultural experience on the cognitive mechanisms of odor categorization. A first cross-cultural study carried out with American, French and Vietnamese students, shows that odor mental representations are formed more likely on the basis of the function associated to the odors in a given culture than on universal perceptual properties. A second cross-cultural study, based on work in other cognitive categories, indicates that olfactory categories seem to be organized according to a typicality gradient and that this internal structure could be determined by perceptual factors such as salience. Thus, due to their salience, some odors may play the role of universal anchors in the organisation of olfactory categories and others, due to their cultural value, may act as specific anchors of a given culture

Abstract:
Des enzymes du métabolisme des xénobiotiques sont présentes au niveau des tissus olfactifs, telles que les enzymes de phase I (cytochromes P450) mais également les enzymes de phase II (UDP-glucuronosyltransférases,. . . ). Elles participent à la détoxication des xénobiotiques mais également à l'éventuelle activation métabolique de ces molécules. Elles pourraient aussi jouer un rôle dans le processus physiologique de la perception des substances odorantes. La phase III est la phase d'excrétion des métabolites mais elle est méconnue au niveau de ces tissus. La présence des enzymes et protéines de phase I, II et III au sein des bulbes olfactifs et de la muqueuse olfactive démontre que ces tissus sont des lieux de métabolisme global non négligeables pour les molécules inhalées (polluants ou solvants). Cependant, cette voie reste intéressante du point de vue de l'administration de médicaments, notamment en vue d'un ciblage vers le cerveau, pour sa rapidité d'action et sa facilité d'utilisation.

Abstract:
Le domaine des parfums et des arômes reste un challenge permanent en recherche. L'impact économique des études sur les molécules olfactives explique le nombre important d'articles qui traitent de méthodes d'analyse de données sensorielles. Cependant, dans ce domaine, la subjectivité de ces informations expérimentales, l'absence de récepteurs cristallisés et le profil multi-odeurs de la plupart des molécules, empêchent de définir, par Modélisation Moléculaire, des modèles prédictifs structure odeur (SOR) robustes. L'utilisation de nouveaux outils de Data Base Mining (DBM), adaptés à l'exploitation de la diversité moléculaire, peut améliorer la connaissance du rôle des descripteurs moléculaires dans le domaine de l'olfaction et, par conséquent, le développement de modèles mathématiques prédictifs. Parmi les différentes méthodes DBM, les techniques dérivées des concepts de la Logique Floue (LF) fournissent des solutions intéressantes aux problèmes de classification dans le cadre des catégories imprécises, parmi lesquels s'insère l'olfaction. Ces concepts regroupent un ensemble de principes mathématiques capables de modéliser l'information à l'aide de fonctions d'appartenances. Très proche de la pensée humaine, la logique floue met en jeu un ensemble de règles d'utilisation courante. Elle permet de se rapprocher de la réalité afin de mieux exploiter les bases de données biochimiques. Ces techniques LF sont combinées aux cartes de Kohonen, pour élaborer une méthode supervisée. Elles sont applicables aussi, directement, dans l'hyperespace d'origine des descripteurs moléculaires. Elles ont montré leur capacité à établir des modèles SOR robustes sur deux séries différentes de composés olfactifs, comportant respectivement trois et quatre notes olfactives. En effet, les modèles prédictifs les plus performants ont permis de classifier correctement, et simultanément, les odeurs d'un ensemble de molécules test avec un taux de prédiction supérieur à 80%.

La détection des phéromones a lieu dans les sensilles des insectes. Elles stimulent les récepteurs olfactifs, induisant des modifications comportementales. Deux classes de protéines solubles, les Chemosensory Proteins (CSP) et les Pheromone Binding Proteins (PBP), sont présentes à haute concentration dans la lymphe sensillaire Leur rôle reste sujet à discussion : solubilisation, spécificité, transport des molécules aux récepteurs ? 1 CSP et 3 PBPs ont été exprimées, purifiées, et la résolution de structure 3D par cristallographie des Rayons X ou RMN a été accompagnée d'études de fluorescence. Les structures de la CSP de Mamestra brassicae (apo et complexée), présentent un repliement nouveau en 6 hélices a, la fixation de ligand induisant un changement conformationnel important. Les 2 structures de PBPs présentées montrent un autre type de repliement en 6 hélices a ;. Il semblerait que le mécanisme de fixation/relargage des ligands dépend de la longueur des PBPs
In insects, pheromones or odor detection takes place in sensilla. They induce behavioural modifications of an individual of the same species. Two different protein classes present in sensilliary lymph are the Chemosensory Protein (CSP) and the Pheromone Binding Proteins (PBP). To date, their precise function remain uncertain : solubilization, specificity, pheromone carrier to receptors. To bring some structural and functional elements, one CSP and three PBP were expressed in E. Coli and purified. They were afterward studied by X-Ray crystallography, NMR and fluorescence. The structures of the apo and complexed CSP (Mamestra brassicae) reveal a new 6 a-helix fold. The protein interacts with aliphatic molecules which induce a large conformational change. PBPs of Leucophaea maderae et Apis mellifera display a different 6 a-helix fold. In this protein family, the mechanism for ligand binding and release may depend of their length

Abstract:
Abstract Insects rely on their olfactory system to forage, prey, and mate. They can sense odorant plumes emitted from sources of their interests with their bilateral odorant antennae, and track down odor sources using their highly efficient flapping-wing mechanism. The odor-tracking process typically consists of two distinct behaviors: surging upwind and zigzagging crosswind. Despite the extensive numerical and experimental studies on the flying trajectories and wing flapping kinematics during odor tracking flight, we have limited understanding of how the flying trajectories and flapping wings modulate odor plume structures. In this study, a fully coupled three-way numerical solver is developed, which solves the 3D Navier-Stokes equations coupled with equations of motion for the passive flapping wings, and the odorant convection-diffusion equation. This numerical solver is applied to investigate the unsteady flow field and the odorant transport phenomena of a fruit fly model in both surging upwind and zigzagging crosswind cases. The unsteady flow generated by flapping wings perturbs the odor plume structure and significantly impacts the odor intensity at the olfactory receptors (i.e., antennae). During zigzagging crosswind flight, the differences in odor perception time and peak odor intensity at the receptors potentially help create stereo odorant mapping to track odor source. Our simulation results will provide new insights into the mechanism of how fruit flies perceive odor landscape and inspire the future design of odor-guided micro aerial vehicles (MAVs) for surveillance and detection missions.

Abstract:
Abstract Insects rely on their olfactory system to forage, prey, and mate. They can sense odorant plumes emitted from sources of their interests with their bilateral odorant antennae, and track down odor sources using their highly efficient flapping-wing mechanism. The odor-tracking process typically consists of two distinct behaviors: surging upwind at higher velocity and zigzagging crosswind at lower velocity. Despite extensive numerical and experimental studies on odor guided flight in insects, we have limited understandings on the effects of flight velocity on odor plume structure and its associated odor perception. In this study, a fully coupled three-way numerical solver is developed, which solves the 3D Navier-Stokes equations coupled with equations of motion for the passive flapping wings, and the odorant convection-diffusion equation. This numerical solver is applied to resolve the unsteady flow field and the odor plume transport for a fruit fly model at different flight velocities in terms of reduced frequency. Our results show that the odor plume structure and intensity are strong related to reduced frequency. At smaller reduced frequency (larger forward velocity), odor plume is pushed up during downstroke and draw back during upstroke. At larger reduced frequency (smaller forward velocity), the flapping wings induce a shield-like air flow around the antennae which may greatly increase the odor sampling range. Our finding may explain why flight velocity is important in odor guided flight.

Abstract The detection and identification of substances that give rise to aromas and off-odors is often a difficult task. Perception of odors is very subjective and odor detection thresholds vary from person to person. The identification of trace levels of compounds responsible for perceived odors is difficult using conventional analytical tools. This paper will focus on a novel method for sampling and analyzing aromatic volatile compounds using an analytical system specifically designed for odor analysis.

Full text
Abstract:
Abstract By performing numerical simulations of the governing fluids and odorant transport equations, this study identified a relationship between the hydrodynamic interactions and olfactory chemoreception in a fish-like school. Simulations were performed using an in-house developed immersed-boundary method based incompressible Navier-Stokes flow solver coupled with the odorant advection-diffusion equation. From a hydrodynamic performance perspective, it was found that the drag of a trailing fish in a synchronous school could be reduced by up to 18% (relative to an in-line school) by introducing a lateral spacing (L) of 0.2 or 0.4 BL relative to the leader. Detrimental wake interactions in the form of strong high velocity regions produced by the leader intercepting the follower head were eliminated at these larger lateral spacings. However, large lateral spacing also led to suppressed surface odor concentration on the trailing fish hence reducing the trailing fish’s ability to detect the presence of the leading fish through chemoreception. At a moderate lateral spacing of L = 0.2BL, the drag induced by the follower is still lower than for the in-line follower (but slightly higher than for L = 0.4BL) and provides a high odor concentration on the body surface. Thus, the moderate lateral spacing serves as a balance between avoiding the detrimental high velocity regions behind the leader and increasing the odor interaction in an in-line synchronous school.

Full text
Abstract:
Hennepin Energy Recovery Center (HERC) is a waste to energy facility owned by Hennepin County and operated by Covanta Energy. HERC has been in operation since 1989. The facility burns 365,000 tons of residential and commercial solid waste per year and generates about 34 mega-watts of electricity that is sold to Xcel Energy. HERC is located on the north side of downtown Minneapolis in the Historic Warehouse District, a neighborhood that is changing from industrial to a more commercial/residential mix with loft conversions and construction of new condominiums. The Minnesota Twins baseball team is also siting a new stadium in the parking lot immediately southeast of the facility. The potential for odors from the tipping floor of the facility affecting the neighborhood has become more of a concern due to the changes in the neighborhood. In March 2004 the County began an odor study. This included developing baseline information on odors from HERC and from the surrounding community by conducting daily odor monitoring at select points on the facility property and throughout the community: • Determining how far odors from HERC migrate into the community. • Quantifying detected odors using a Nasal Ranger. • Determining the factors that contribute to these odors. • Developing a method of controlling these odors. • Continued monitoring to determine the impact of mitigation methods. Odors detected were characterized as garbage odors, garbage-related odors, and neighborhood odors. Baseline data showed that while garbage odors from HERC were mostly undetectable beyond the perimeter of the property, there was room for improvement in decreasing the presence and intensity of these odors. The tipping hall was designed to operate under negative pressure to control odors, however the entrance and exit doors were always open and a negative pressure could not be maintained.

Abstract:
A feasibility study was conducted, aiming to explore the potential effectiveness of UV/TiO2/O3 photooxidation technologies for simultaneous treatment of odorant and pathogen emissions from livestock and poultry operations. Several key parameters were tested in laboratory (US) and semi-pilot (Israel) scale conditions including: the effects of light energy dose (treatment time and light intensity), relative humidity and air temperature, UV wavelength, presence of photocatalyst (TiO2) and the presence of ozone. Removal and conversion of odor, target gases (sulfur-containing volatile organic compounds S-VOCs, volatile fatty acids (VFAs), phenolics, and ammonia), and airborne pathogens was tested. Up to 100% removal (below method detection level) of S-VOCs, VFAs, and phenolics, the overall odor, and up to 64.5% of ammonia was achieved with optimized treatment. Treatments involving deep UV band (185 nm) and photocatalyst (TiO2) were more efficient in removal/conversion of odorous gases and odor. The estimate of the operational cost of treatment was based on measured emissions of several odorous VOCs from full scale, commercial swine farm ranges from $0.15 to $0.59 per finisher pig. This figure represents significantly lower cost compared with the cost of biofiltration or air scrubbing.

Full text
Abstract:
Phytophagous insects respond to chemicals from their host plants in a number of ways, including orientation or attraction in response to volatiles produced by plants. Orientation to odors from host plants may occur in order to locate food, mates, or oviposition sites. A detailed understanding of these behaviors are the chemical stimuli evoking them may provide useful means for attracting and trapping insect pests of crop plants. Heliothine moths (Helicoverpa and Heliothis herein) include a number of major pests of cultivated crop plants throughout the world. In North America, these include Heliothis virescens and Helicoverpa zea. In much of Eurasia (including Israel) Australia, and Africa, these include Helicoverpa armigera and Helicoverpa peltigera. These 4 species of concern all are attracted to odorants from host plants (Tingle and Mitchell 2992, Mitchell et al 1991, 1992 BARD feasibility study report). Host plant chemicals also play a role in the sexual behavior of Helicoverpa species. Synthesis and possibly release of sex pheromone in H. zea and H. phloxiphaga is stimulated by kairomones from hosts plants (Raina 1988, 1992). Pheromona scent marking on host plants also occurs in H. virescens and H. zea. Studies of several other insects, including the cabbage looper Trichoplusia ni, have a variety of other behaviors may occur in association with host plants, including the use of plants as sexual rendesvous sites and of direct involvement of plant chemicals in sexual behavior. Some pest species of moths also may use host plants as adult food sources. These studies were undertaken to develop a more thorough understanding of how Heliothis/Helicoverpa moths use host plant odorants to locate and select foods, mates, and oviposition sites. We used Heliothis virescens and Helicoverpa zea in Florida, and Helicoverpa armigera and Helicoverpa peltigera in Israel as objects of study because of their pest status. It is hoped that such an understanding will provide direction for work to discover and develop novel means to control these pests through behavioral manipulation. The specific objectives of the proposal were to 1) identify host odor affects on known Heliothine sexual behavior, 2) identify novel sexual behavior that is how dependent, 3) isolate and characterize host kairomones important to pest Heliothine host and mate-location behavior, and 4) investigate female attraction to males.

Abstract:
Cedrela odorata is one of the most important commercial Neotropical forestry species, harvested mainly from natural forest, what have taken the species to danger of extinction. Its commercial plantation is limited by Hypsipyla grandella attacks, which could reach 100% of individuals in a forest plantation (Figure 1). Inverse relation of available calcium concentration in the soil for C. odorata and attacks of H. grandella had been reported (da Silva et al., 2009). Some studies indicate that calcium and boron addition to the soil has a positive e ect in height growth of Swietenia macrophylla (da Silva Junior et al., 2014); nevertheless, some studies suggest that when growth is high there is an increase in attack probability (Newton et al., 1993). Then some clarity on this subject is required.

Identification of Impact Aroma Compounds in Tomato: Implications to New Hybrids with Improved Acceptance through Sensory, Chemical, Breeding and Agrotechnical Techniques. United States Department of Agriculture, October 2002. http://dx.doi.org/10.32747/2002.7585204.bard.

Full text
Abstract:
The tomato, a profitable vegetable crop in both the USA and Israel, has benefited significantly from intensive breeding efforts in both countries, and elsewhere (esp. Holland). : Modem hybrids are highly prolific and resistant to a variety of major pests. They produce attractive, firm fruit for both processing and fresh-marketing. In all cases, however, reduction in flavor and aroma have occurred concomitantly with the increase in yield. Sugars-acids ratio dominate fruit taste, whereas aroma volatiles (potent at minute ppb and ppt levels) contribute to the total characteristic tomato flavor. An increase in sugars (1-2%) contributes significantly to tomato fruit taste. However, because of energy reasons, an increase in fruit sugars is immediately compensated for by a decrease in yield. Our main objectives were to: (a) pinpoint and identify the major impact aroma components of fresh tomato; (b) study the genetic and environmental effects on fruit aroma; (c) determine precursors of appealing (flavors) and repelling (off-flavors) aroma compounds in tomato. Addition of saturated salts blocked all enzymatic activities prior to isolation of volatiles by dynamic and static headspace, using solvent assisted flavor evaporation (SAFE) and solid phase micro-extraction (SPME) from highly favored (FA-612 and FA-624) and less preferred (R 144 and R 175) tomato genotypes. Impact aroma components were determined by gas chromatography-olfactometry (GC-O), gas chromatography-mass spectrometry (GC- MS) and aroma extract dilution analysis (AEDA). The potent odorant (Z)-1,5-octadien-3-one, was identified for the first time in fresh tomato. From the ca. 400 volatile compounds in the headspace of fresh tomato, the following compounds are proposed to be impact aroma compounds: (Z)-3-hexenal, hexanal, 1-penten-3-one, 2-phenylethanol, (E)-2-hexenal, phenyl acetaldehyde, b-ionone, b-damascenone, 4-hydroxy-2,5-dimethyl-3-(2H)-furanone (FuraneolR), (Z)-l,5-octadien-3-one, methional, 1-octen-3-one, guaiacol, (E,E)- and (E,Z)- 2,4-decadienal and trans- and cis-4,5-EPOXY -(E)-2-decenal. This confirms the initial hypothesis that only a small number of volatiles actually contribute to the sensation of fruit aroma. Tomato matrix significantly affected the volatility of certain impact aroma components and thus led to the conclusion that direct analysis of molecules in the headspace . may best represent access of tomato volatiles to the olfactory receptors. Significant differences in certain odorants were found between preferred and less-preferred cultivars. Higher consumer preference was correlated with higher concentrations of the following odorants: l-penten-3-one, (Z)-3-hexenal, (E,E)- and (E,Z)-2,4-decadienal and especially Furaneol, whereas lower consumer preference was associated with higher concentrations of methional, 3-methylbutyric acid, phenylacetaldehyde, 2-phenylethanol, and 2-isobutylthiazole. Among environmental factors (salinity, N source, growth temperature), temperature had significant effects on the content of selected aroma compounds (e.g., 3-methylbutanal, 1- penten-3-one, hexanal, (Z)-3-hexenal, (E)-2-hexenal, 2-isobutylthiazole, 6-methyl-5-hepten- 2-one, 1-octen-3-one, methional, 2-phenylethanal, phenyl acetaldehyde, and eugenol) in fresh tomatoes. Salt stress (20 mM NaCl) increased the content of odorants such as (Z)-3-hexenal, 2-phenylethanol and 3-methylbutanal in the R-144 cultivar whereas salinity had minor effects on 1-pentene-3-one, 2-isobutylthiazole and b-ionone. This fundamental knowledge obtained by comprehensive investigation, using modem chemical, sensory and agrotechnical methodology will assist future attempts to genetically modify the concentrations of key odorants in fresh tomatoes, and thus keep the tomato production of Israel and the USA competitive on the world market.
