- A cross-cultural perspective on feeling good in the context of foods and beveragesPublication . Sulmont-Rossé, Claire; Drabek, Rafal; Almli, Valérie L; van Zyl, Hannelize; Silva, Ana Patricia; Kern, Martin; McEwan, Jean A.; Ares, GastónThe aim of the present research was to explore consumers' conceptualization of feeling good in relation to food and beverages from a cross-cultural perspective. Participants from 14 countries across 5 continents and covering 10 languages (N = 8325) responded to an online survey including word association and free listing tasks related to feeling good in the context of food and beverages. Results were analyzed using inductive coding: a list of main codes was generated in English for each of the tasks, after which native speakers for each language coded the responses. Codes were grouped into categories reflecting common themes from which eight dimensions were identified. Results showed that in the context of foods and beverages, feeling good was mainly associated with specific foods and sensory and hedonic properties. Across the 14 countries, ‘Sweet and fat food’, ‘Fruit and vegetables’, and ‘Protein food’ were the three food categories most associated with feeling good. Emotional aspects of food consumption (‘Taste good’ and emotions) were also relevant. Health and nutrition-related aspects were more relevant for consumers when they were asked to think about how foods and beverages would make them feel good in the future. In other words, food-related feeling good seems to be mainly driven by sensory pleasure at present, but it is also related to nutrition and health in the future. Differences in the strength of the associations between feeling good and the identified categories were found between countries, in line with the existence of cultural differences in food habits, as well as in the importance people attach to the characteristics of foods and beverages. Results from the present work provide insights on the impact of eating and drinking on feeling good in terms of emotional, physical and social aspects, and increase knowledge about the way food and drink can contribute to general well-being
- Effect of adding hop aroma in beer analysed by temporal dominance of sensations and emotions coupled with temporal likingPublication . Silva, Ana Patricia; Voss, Hans-Peter; van Zyl, Hannelize; Hogg, Tim; Graaf, Cees de; Pintado, Manuela; Jager, GerryIndividual sensory properties of food and beverages are not perceived independently during consumption and their interaction will determine what consumers perceive and prefer. Many dynamic processes are involved in flavour release during the consumption experience and therefore its perception should be measured dynamically. To investigate how dynamic sensory and emotion profiles interact and how this relates to temporal liking, this study used a multi-sip approach with temporal dominance of sensations (TDS), temporal dominance of emotions (TDE) and temporal liking (TL), to compare three beers with small sensory differences in hop aroma: control beer (0% hop aroma), low_c beer (0.08% hop aroma) and high_c beer (0.16% hop aroma). Seventy-one beer consumers consumed a glass of each beer while performing TDE + TL and TDS + TL, on consecutive days in a sensory lab. Adding different concentrations of hop aroma in beer resulted in different dynamic sensory profiles without a difference in liking. The attribute floral was dominant in the high_c beer and in the last stage of consumption. TDE revealed an improvement of the emotional profile of the high_c beer at the beginning of consumption: three positive emotions, relaxed, pleased and happy were dominant, whereas for the other beers, one positive and one negative emotion were dominant, relaxed or pleased and disappointed. Overall differences between beers based on total duration of dominance were clear when looking at sensations rather than emotions while the combination of dynamic profiles of sensations and emotions showed a slight discrimination between the beers. It can be concluded that the subtle changes in the aroma resulted in differences in temporal dominance of sensations, did not affect liking and only slightly changed the emotion profile. The method used in this study remains to be proven further for use in food-related research and new product development, especially in the case of subtle changes.
- What’s in a name? The effect of congruent and incongruent product names on liking and emotions when consuming beer or non-alcoholic beer in a barPublication . Silva, Ana Patricia; Jager, Gerry; Voss, Hans-Peter; van Zyl, Hannelize; Hogg, Tim; Pintado, Manuela; Graaf, Cees deThis study concerns the expectations, liking and emotions related to the consumption of conventional beer and non-alcoholic beer (NAB), which are related but different products. These beverages are derived from the same raw materials and have undistinguished visual sensory cues. However consumers acknowledge the differences between them in terms of flavour, functional and emotional conceptualisations. Of particular interest here is how prior experience with beer and NAB and the conceptual information this generates in a consumer, can influence his or her response to its consumption in an appropriate setting - a bar. The labelling of a sample as beer or non-alcoholic beer was employed as a prompt to study the effects on liking and emotions provoked, when drinking a beer or a NAB, in a bar. Over 4 sessions, 155 consumers drank a glass of beer or NAB under two different conditions, labelled either correctly or incorrectly with respect to the actual composition of the sample. Questionnaires were used to rate the liking and emotions prior to and after consumption. The naming of NAB as beer significantly increased the liking and changed one emotion towards a positive direction, namely participants felt more fulfilled. When beer was presented as NAB it did not affect the liking but did significantly reduce the intensity of six positive emotions. Participants felt less comforted, exuberant, good, happy, joyful and loving. This study showed that labelling and the conceptual information generated in consumers might influence their response after consumption of these beverages.
