Athletic abs or big bellies:The impact of imagery, arousal levels, and health consciousness on consumers’ attitudes towards plant-based protein produ…
2021
Abstract Research suggests that health-related imagery influences consumers’ product attitudes, and that both appetitive, positively framed and aversive, negatively framed imagery can be used to boost health-related responses. Arousal has been suggested as a mechanism driving such responses, but few studies in food-related consumer research have examined the link between arousal and consumers’ product attitudes. The present cross-national study, involving almost 1000 consumers (N = 959) from Denmark, Germany, Spain, and the UK, experimentally investigated whether prior exposure to healthy (vs. unhealthy) imagery influences consumers’ attitudes towards a plant-based protein product.

P073 L’obésité diminue, de manière réversible, la préférence pour les lipides alimentaires chez la souris
2013
International audience; Introduction et but de l’étude. – Au cours des dernières années, il a été suggéré l’existence d’un lien étroit entre la détection oro-sensorielle des lipides alimentaire, la régulation de la prise alimentaire et l’IMC. Toutefois, les mécanismes affectant la sensibilité aux lipides ainsi que l’éventuelle implication directe de l’obésité restent mal connus.
Sensory exploration of the freshness sensation in plain yoghurts and yoghurt-like products
2013
WOS: 000324008600021 ; http://www.sciencedirect.com/science/article/pii/S0950329313001092; International audience; The term "freshness sensation" is used by consumers for characterizing some plain yoghurts and yoghurt-like products. This study consisted in an investigation of this sensation aiming at determining its underlying sensory attributes. First, two focus groups of consumers were conducted to open up the framework. A set of plain yoghurts and yoghurt-like products, both commercial and experimental, was then subjected to sensory analysis. The samples were sorted by means of a free sorting task, and further scored for the intensity of their freshness sensation and their liking, by 72 …
Dynamics of liking for flavoured crackers: Test of predictive value of a boredom test
1998
Abstract The principal aim of this study was to compare two experimental conditions for measuring the effect of repeated consumption on liking: a laboratory boredom test and a home use test. Another goal was to investigate the impact of perceived familiarity, appropriateness and complexity on the dynamics of liking. Two groups of consumers were recruited, one for each condition. Five variants of salty crackers, each with a different flavour, were tested. The laboratory condition did not show any difference in the dynamics of liking among the flavours. The home condition revealed a significant increase in liking for only one flavour. This increase could not be related to the level of complex…
Do vegetarians feel bad? Examining the association between eating vegetarian and subjective well-being in two representative samples
2020
Abstract Research on the relationship between vegetarianism and subjective well-being (SWB) has produced inconsistent results, which may partly be due to small sample sizes and divergent operationalizations of well-being. For these reasons, the present study aimed to thoroughly examine this association in two large representative samples from Germany (Study 1: N = 12,905, including 665 vegetarians) and Australia (Study 2: N = 15,532, including 383 vegetarians) using a consensual conceptualization of SWB (composed of an affective component, i.e., positive and negative affect, and a cognitive component, i.e., life satisfaction). Results of t-tests showed that vegetarians reported slightly hig…
Internal and external mapping of preferences for commercial lager beers : comparison of hedonic ratings by consumers blind versus with knowledge of b…
2001
Abstract The individual preferences of 170 consumers in six categories of age (20s, 30s, 40s) and gender (men, women) for 24 domestic, imported or specialty lager beers, tasted first blind and then with knowledge of brand and price, were investigated by preference mapping techniques. Internal preference mapping revealed differences in the preferences of consumers, with some consumers preferring domestic or ice beers, and others preferring specialty or imported beers. Hedonic ratings changed significantly from the blind to the informed tasting condition, particularly for consumers in their twenties, thereby documenting the significant role of non-sensory variables in the formulation of a hed…

Uses of change-over designs and repeated measurements in sensory and consumer studies
1993
Abstract The paper illustrates two statistical methods, the design and analysis of sensory experiments taking into account the effects of serving order and previously assessed treatment and the analysis of experiments with time repeated measurements. Change-over design experiments balance both presentation order and carry-over effects. The proper analysis of variance allows the testing of these effects and the estimation of product means adjusted for carry-over effect. Repeated measurements occur when groups are being compared over time. Either a corrected split-plot or a multivariate analysis of variance (MANOVA) with measurements at different times forming the variable should be adopted t…
Traditional process: influence on sensory properties and on consummers' expectation and liking application to "pâté de campagne"
2000
Abstract Sensory profiling of eight ‘pâtes de campagne’, of which four were produced according to a traditional process and four produced according to a non traditional process, was performed by a trained panel. Results revealed some sensory particularities of each process but also sensory differences among the eight products which were not related to the process. Expectations created by two labels, one evoking a traditional and one evoking a non traditional process for ‘pâte de campagne’, were determined for 125 consumers. The impact of these expectations on expectation after visual examination and on liking after tasting was also studied, using the same eight products. The impact of infor…
A prospective study of food preferences in childhood
2004
Abstract This study has evaluated the impact of food choices at 2–3 years old on food preferences later in life, by following up the same subjects. Early preferences were estimated through recordings of food choices conducted in a nursery canteen in children aged 2–3, from 1982 to 1999. The children were free to choose the composition of their lunch from among a varied offering of eight dishes. The same subjects ( n =341) were contacted in 2001–2002 and so their ages varied from 17–22 ( n =91), 13–16 ( n =68), 8–12 ( n =99) to 4–7 ( n =83). Their present preference for the 80 foods most frequently presented at the nursery canteen was assessed through a questionnaire. Five food categories we…
