- 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.

- The previous 'Scandinavian' Weurman Flavour Symposium held in Oslo, Norway, in 1987 had as the main themes chemistry, biotechnology, sensory science and data analysis in flavour research [1]. Since then, many advances have been made, however, when comparing with the Weurman Symposium in 2005, the subject areas and topics of research have not changed very much. Flavour scientists still work with identification of aroma and taste components in foods, their formation, stability and release as well as sensory and data analytical aspects. The knowledge about flavour components in foods and the understanding of the way we perceive them has though considerably expanded. Advances have also been made in the way one can analyse flavours in foods and beverages, and measure responses from and in human subjects. One can say that the toolbox with methods and techniques for flavour analysis has expanded remarkably offering many new possibilities to understand flavour from different perspectives and levels of details. The workshop presented some state-of-the-art applications of modern in vivo and in vitro flavour analysis as well as visual sensory assessments of meals made by machines equipped with sensors and artificial networks processing capability. Also, new ways of studying multisensory processes by stimulating sensory subjects with defined stimuli were discussed. Intelligent 'artificial perception' systems may replace some routine sensory analysis and monotonous production tasks in the future, but the development of such systems still require sensory assessments by humans. © 2006 Elsevier B.V.

- Background: A health promoting diet is suggested to be tailored to regional circumstances to preserve the cultural diversity in eating habits, as well as contribute to more environmentally friendly eating. It may influence consumer acceptance, however, if the components of the diet differs considerably from their habitual food. Objective: This study aimed to investigate whether snack bars composed of Nordic ingredients were accepted by 8-11 year-old Danish (n=134) and Swedish (n=109) children. Design: A seven-point hedonic scale was used to measure the children’s acceptance of five snack bars that varied in their composition of whole grains, berries and nuts. A preference rank ordering of the five bars was also performed. Results: The results showed that samples that were rated highest in liking and were most preferred in both countries were a kamut/pumpkin bar and an oat/cranberry bar. The sample with the lowest rating that was also least preferred was a pumpernickel/sea buckthorn bar. Flavour was the most important determinant of overall liking followed by texture, odour and appearance. Conclusions: Children’s acceptances and preferences were highly influenced by the sensory characteristics of the bars, mainly flavour. In agreement with earlier studies, the novel food ingredients seemed to influence children’s preferences. The Nordic snack bars may have a potential to be a snack option for Danish and Swedish school children, but repeated exposures to the products are recommended to increase children’s acceptance.
