Crossmodal correspondences between typefaces and food preferences drive congruent choices but not among young consumers
2022
Abstract Several studies suggest that consumers match stimuli across sensory modalities, with angular (vs. round) typefaces typically associated with sourness (vs. sweetness). Drawing on findings from the field of crossmodal correspondences, this study (N = 220) examined potential typeface effects in naturalistic settings and found that exposure to angular (vs. round) typeface increased (decreased) consumers’ preferences for sour (sweet) food but had no impact on their expectations or perceptions of these tastes. Moreover, while typeface did not have a direct effect on food choices, consumers exposed to angular (vs. round) typeface reported a greater relative preference for sour over sweet …
Les perceptions gustatives chez l'enfant
2005
As soon as the end of gestation, the gustatory system is stimulated by the taste-active compounds carried by the amniotic fluid and its maturation continues until mid-childhood. Facial expressions and relative ingestion methods show that the newborn can discriminate the various taste qualities (bitter, salty, sour, sweet and umami). The range of individual responses is wide. Neonatal reactions to sweet and umami are generally considered to express pleasure. The bitter and sour stimulations lead to hedonically negative reactions. The response to salt taste is less characteristic. Overall, the attraction towards sweet and the rejection of bitter and sour tastes become more pronounced during c…
Perceived minerality in sauvignon blanc wine: chemical reality or cultural construct?
2016
International audience; The study aimed to determine the relationship between perceived mineral character in wine and wine chemical composition. We investigated the sensory properties and chemical composition of sauvignon blanc wines from two major sauvignon-producing countries, New Zealand and France. Sensory experiments employing 16 wines (8 French, 8 New Zealand) were conducted in Marlborough, New Zealand and in three regions of France, namely Bordeaux, Burgundy, and the Sancerre/Loire region. Wine professionals (31 New Zealanders and 32 French professionals) sensorially characterised the 16 wines under three conditions, bouquet only (ortho-nasal olfaction), palate only (nose clip condit…
Different sensory aspects of a food are not remembered with equal acuity
2009
International audience; In the present study, food memory for three sensory aspects involved in food perception, taste, texture and aroma, is compared. Participants received a lunch including a custard dessert (target) under incidental learning condition. One day later, participants were presented with samples identical to the target and with distractors varying either in sweetness, thickness or cherry aroma. Memory was assessed by an absolute recognition question (“Did you eat this sample yesterday?”) and by relative questions (“Is this sample less, equal or more sweet than the sample you ate yesterday?”). Results showed better memory performance for sweetness than for the two other sensor…
Familiarity and liking playing a role on the perception of trained panelists: A cross-cultural study on teas
2015
Consumers cultural background is known to influence their food choice. To better understand the sensory perception across cultures, it is helpful to work with both a descriptive panel and consumers. This study examined how tea products of differing fermentation levels were described and liked by different cultures. Seven tea samples were evaluated by Korean and French trained panels and consumers. The trained panels evaluated the samples on appearance, flavor, and mouthfeel. The consumers rated the samples on acceptability and familiarity. The result indicated that both descriptive panels experienced varying degrees of taste and odor cross-modal interaction. On the unfamiliar samples, Frenc…
Contribution of the Temporal Dominance of Sensations (TDS) method to the sensory description of subtle differences in partially dealcoholized red win…
2009
Abstract In this study, effect of partial alcohol reduction on the sensory modification of red wines was investigated. A Merlot and a Syrah wine were partially dealcoholized using reverse osmosis technique to span a range of three different alcohol contents (14–10%) by grape variety. Preliminary triangle tests indicated the existence of very slight differences between the dealcoholized wines of the study. Therefore, adapted descriptive methodologies had to be used. In a first step, wines were described with a comparative sensory profile by 16 trained panellists on 15 sensory attributes. Then, the same panellists profiled the wines with the TDS technique, which consists in identifying and ra…
The effect of glycerol on the perceived aroma of a model wine and a white wine
2001
Abstract Glycerol is one of the most abundant components of wine. In dry wines its concentration is only exceeded by water and ethanol. Several studies have been carried out on the effects of glycerol on mouthfeel, but little attention has been given to glycero–flavour interactions. Consequently, here we have turned our attention to the aroma perception. Purge and Trap analysis and sensory measurements were used to investigate the modifications in volatility of aroma compounds in model solutions and white wine according to their glycerol concentration. In water, the amount of aroma compounds released was not affected by the presence of glycerol concentrations ranging from 5 to 50 g/L. The a…
Microbiological Characterization of Red and White Wines Originated From Vineyards of Getic Piedmont
2014
Abstract The aim of the present paper is to investigate an objective microbiological analysis of the wine by identification of some parameters such as total amount of germs and yeastswhich are contained in the quality wines from Getic Piedmont namely: Bolovanu, Corcova, Drăgășani, Sâmburești, Segarcea, Ștefănești.The Getic Piedmont is a relict geomorphological relief unit with significant variations from the flat, low lands fragmented by moderately rough with strong fragmentation. We have selected by grouping the wines in grape varieties, white wines (Sauvignon, Chardonnay, Riesling) and red wines (Merlot, Cabernet, Pinot noir) which were tested by microbiological tests. The opinion that th…
Evaluation of French and New Zealand Sauvignon wines by experienced French wine assessors
2010
International audience; Certain odours are commonly associated with the bouquet of Sauvignon blanc wine. These characteristic varietal odours can vary to reflect origin of a Sauvignon blanc wine. In the present study, Sauvignon blanc wines from sub-regions of Marlborough, New Zealand, and from north France (Sancerre, Loire, and Saint Bris) were investigated in terms of (i) distinctiveness of country of origin, (ii) odour profile, and (iii) the concept of typicality (Ballester, J., Dacremont, C., Le Fur, Y., & Etievant, P. (2005). The role of olfaction in the elaboration and use of the Chardonnay wine concept. Food Quality and Preference, 16, 351-359). Twenty-three experienced French wine ta…
Sensory and chemical characterisation of Sauvignon blanc wine: Influence of source of origin
2011
Abstract The main objective of the study was to investigate influence of geographical location on volatile composition and perceived flavour profile of Sauvignon wines of New Zealand (Marlborough), French (Sancerre; Loire; Saint Bris), and Austrian (Styria) origin. Nineteen New Zealand wine professionals evaluated 18 Sauvignon wines, 6 from each source of origin, by sensory methods that included intensity ratings to experimenter-provided descriptors, typicality ratings, and classification tasks (non-directed and directed sorting). Results demonstrated that wines from the three sources of origin were separated by sensory analyses, with New Zealand wines dominated by perceived green character…
