- Facially expressed emotions play a role in communication between individuals. They form another means of expressing oneself besides verbal expressions or self-reporting of feelings and perceptions on psychometric scales and are implicit in nature. This study aimed to evaluate the extent and specificity of evoking facial expressed emotions by basic tastes and to evaluate if facially expressed emotions provide additional information to explicit measures. The emotions were characterised upon tasting the five basic tastes in aqueous solutions at three different concentrations levels. The sensory and emotional responses reported were obtained from a 21-membered taste panel. Facial reactions and facially expressed emotions depended on the taste quality and taste intensity. However, the facially expressed emotions were generally weak even for the relatively strong taste intensities. Bitter (caffeine), sour (citric acid) and salty (sodium chloride) lead to clear disgust and surprise responses, whereas, sweet (sucrose) and umami (glutamic acid monosodium salt) taste gave weakly noticeable facially expressed emotions. Although correlations between the expressed emotions and hedonic responses were observed, the affective experience had a limited predictive ability for the facially expressed emotion at the individual level. In conclusion, psychometric rating of the hedonic response is easier to assess than facially expressed emotions although it may not completely represent the dimensions of the emotional experience.

- Background & aims: Children's food choices are guided by their preferences. It is established, however, that repeated exposure to a novel food increases children's acceptance. This study investigated how acceptance of an initially liked and disliked snack bar develops in 9-11 year-old children. Methods: 315 children were randomised into three groups: A control group (n = 111) and two groups exposed to an initially liked kamut bar (n = 94) and an initially disliked sea buckthorn bar (n = 110). Acceptance of both bars was tested before and after the exposure period, and on the 9th exposure. Results: Intake of both bars increased significantly in the exposure groups. There was no difference in the control groups' intake or liking of the bars between pre and post-testing. Liking rose significantly for children exposed to the disliked sea buckthorn bar, while this was not observed in children exposed to the liked kamut bar. In a post-test children exposed to kamut bars had higher intake of that bar than non-exposed children. This was also observed for the sea buckthorn bar that was also given significantly higher liking scores by the exposure group. Conclusions: The majority of children exposed to an initially disliked bar increase acceptance after nine exposures to the same level as an initially liked bar. Children repeatedly exposed to a liked bar show stable acceptance.

- Basic taste solutions induce sensory perceptions via taste receptors and give rise to specific facial reactions. Many of these have been shown to be innate. The aim of this study was to explore relationships between the sensory perception of basic taste solutions at different concentrations and facial reactions. Basic taste solutions each at three levels plus water were served to a panel. The assessors individually identified quality, intensity and pleasantness. They were recorded during tasting and their facial reactions (based on FACS) were coded and analysed. Facial reactions indicated both quality and concentration of the stimuli. The intensity of most facial reactions increased with increasing stimulus concentration, most pronounced for sourness (lips) and bitterness (eyes and forehead). Pleasantness ratings decreased with increasing concentrations of all basic tastes. Water and the lowest sucrose concentration were perceived as the most pleasant samples and gave rise to the lowest intensity of facial reactions. The study showed that a combination of sensory analyses and facial expressions was successful in adding further insight to the knowledge of perception of basic tastes.

- Acceptance of texture-modified meals in healthy older adults with pre-clinical symptoms of dysphagia may facilitate gradually transitioning to a soft diet. Little is known about the sensory attractiveness of such meals in home living older adults. This study aimed to examine liking among a group of healthy, independent older adults for texture modified chicken breasts and gravy. A secondary aim was to evaluate liking in relation to olfactory- and taste function. Texture-modified chicken breasts were prepared to appear identical to the unmodified chicken breasts. This is a new approach which aims to improve visual appearance of the meal compared to existing texturemodified meals. Ordinary chicken breasts obtained significantly higher liking scores across all sensory parameters compared to the texture-modified products. Texture modified chicken breasts need further adjustment for a broad acceptance. Adding flavor-enhanced gravy did not change the liking pattern. This study supports the notion that texture plays a central role for meal acceptance.

- In Europe the percentage of citizens aged 65 and over is increasing at an unprecedented rate, and is expected to account for over 30% of the population by 2050. Coupled with an increase in life expectancy, this massive demographic change calls for a major effort to ensure quality of life in our older population. A thorough understanding of the elderly as food consumers, their nutritional needs, their food perception and preferences is increasingly needed.The role of food in healthy aging was a prominent theme at the 6th European Conference on Sensory and Consumer Research, which had quality of life across the life span as a focal point. This short paper is based on a workshop held at the EuroSense meeting, focusing on research from sensory and consumer scientists. The workshop featured contributions focusing on food-related perception, needs and behavior of the elderly, and aimed at demonstrating the relevance of sensory and consumer scientists in promoting food-related well-being in an aging population. The workshop contributions are here reviewed and summarized three main themes: nutritional needs, food perception and aging, and behavioral drivers of food consumption.

- Motoric eating difficulties affecting the ability to eat according to established norms may result in loss of autonomy, reduced food intake and decreased social interaction. Finger food meals may affect the ability to eat independently and were therefore compared to regular meals for older adults >65 years with major motoric eating difficulties. In this pilot study the screening instrument MEOF-II, including additional questions about use of cutlery and fingers, was used to collect data regarding autonomy, food intake and social interaction through observations. Five women and one man participated in the study. Results showed that finger food meals facilitated autonomous eating since the participants were able to eat independently without relying on help from others. Less energy was spent on eating, which allowed for social interaction. However, finger food meals entail unfamiliar norms and culinary rules which may hinder eating; this is an important factor to consider in the implementation of such meals. Further studies on finger foods for older adults may consider larger and diverse cohorts, including healthy older adults, those with motoric difficulties and those with early stages of cognitive decline. Also, a wider variety of finger foods for specific cultural preferences and situations may be considered.

- Difficulties of managing cutlery, manipulating food on the plate and transporting food to the mouth may negatively influence the ability for self-provision and nutritional status among older adults with motoric eating difficulties. The purpose was to explore perceptions and attitudes about eating with the fingers among older adults with motoric eating difficulties, and relatives and professional caregivers of older adults with motoric eating difficulties. Qualitative data was collected through individual interviews with older adults >65 years ( N = 14) with motoric eating difficulties and focus groups with relatives ( N = 15) and professional caregivers ( N = 15). Data was analyzed using deductive and inductive content analysis. Although the older adults had normative ideas about proper eating and culinary rules, they regularly consumed several foods with their fingers without previously reflecting upon this. Using bread to grip or wrap foods and inserting skewers into foods may increase the acceptability of eating with the fingers. However, the importance of the disease causing the eating difficulties, how it was perceived, and its severity were crucial in understanding how eating with the fingers was perceived. Finger foods may be suitable for older adults with major eating difficulties because they have developed a self-acceptance in relation to their condition over time.

- The purpose of this study was to develop and evaluate finger food components as part of a complete meal for older adults with major motoric eating difficulties. Overall, the evaluation of sensory characteristics as well as texture analysis forms a valuable basis for further development of a meal that can be eaten without cutlery, comprising flatbread, beef rolls and brown sauce. The nutritionally enriched flatbreads were generally perceived as neutral in odour and flavour, while higher concentrations of protein and fat influenced the texture negatively. Although bread was not commonly eaten with a meal, the consumer evaluation stressed the importance of texture of flatbreads intended for wrapping. Differences between meat cuts were not pronounced; however, beef rolls made from inner thigh were perceived as more tender and crumblier than beef rolls made from outer thigh. Moreover, the odour and flavour intensity were thought to be higher in beef rolls braised in rolls due to the caramelised surface. However, tenderness was considered the most important parameter for beef rolls whereas crumbliness and dryness in tender meat can be compensated for by serving the meat with sauce. In fact, sauce was found to play an important role in a well-accepted meal. The addition of sweet, sour, or bitter tastes to brown sauces, to investigate the effect of basic tastes, reduced the perceived intensity of the original flavour profile of the brown sauces. Finally, combinations of the developed meal components could be investigated further to create attractive finger food meals for those unable to eat with knife and fork. © 2022 The Authors
