    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

    Implementing immersive technologies in consumer testing: Taste perception and liking in a laboratory, immersive simulated café and real café
    Dijksterhuis, G.B. ; Kaneko, D. ; Wijk, R.A. de; Zoggel, M. van; Schiona, Irene ; Zandstra, E.H. - \ 2019
    Food perception and emotion measured over time in-lab and in-home

    Eating context - Facial expressions - Heart rate - Repeated sensory tests
    Background: Real-life human eating behaviour does not take place in a vacuum, rather it happens in context. The context in which consumers eat their foods influences the acceptance of the consumed foods. Consequently, consumers’ hedonic and sensory ratings elicited in a natural consumption context will differ from those elicited under controlled sensory laboratory conditions. Moreover, foods are rarely consumed on one single occasion but are typically consumed repeatedly and ratings may change over repeated consumptions as well. Often, consumer acceptance is tested explicitly, for example with liking ratings, especially when the testing is done outside the laboratory. Implicit tests such as facial expressions and physiological measurements of the autonomic nervous system can provide additional information on consumer acceptance. As a result of technological advantages, such tests are no longer limited to the laboratory but can also be used in natural consumption contexts. Method: Eighteen healthy Dutch consumers (18–65 years of age) tested four test foods plus a warm-up sample ten times on consecutive weekdays and on similar hours using their own laptop and webcam. Test locations alternated between the sensory laboratory and the participant's own home. Explicit measures included liking scores and scores on ten sensory taste/flavour/texture attributes, and implicit measures included facial expressions, heart rate and consumption duration using Face Reader TM . This study was the first to validate the Face Reader TM for usage at home. Results: The liking scores and sensory profiles varied between test foods (p < 0.05), but not between test locations and only some specific sensory attributes showed systematic variation over repeated consumption. In contrast, implicit measures showed systematic effects of test foods, test locations, and repeated consumptions (p < 0.05). Compared to consumption in the laboratory, consumption at home was faster, triggered higher heart rates, and triggered more intense facial expressions of happiness, contempt, disgust and boredom. Conclusions: Implicit tests were more sensitive to effects of test location and repeated consumption than explicit tests. Additional research is required to investigate the relevance of these measures to long term consumer acceptance of food products.
    Effects of eating context on food perception are not caused by the eating location itself
