The TeRiFiQ project: Combining technologies to achieve significant binary reductions in sodium, fat and sugar content in everyday foods whilst optimi…
2017
International audience; Most developed countries are confronted with rising rates of diseases related to unhealthy eating habits, particularly the excessive consumption of salt, saturated fat and free sugars. However, fat, sugars and salt in food influence not only its nutritional qualities but also its sensory properties, safety (e.g. shelf life) and affordability. The main challenge is to formulate healthier foods that are acceptable to consumers. In this context, the overall objective of TeRiFiQ was to achieve significant binary reductions in the salt-fat and sugar-fat contents of frequently consumed food products around Europe, while, at the same time, ensuring the products’ nutritional…
Study of the polysemic term of minerality in wine: Segmentation of consumers based on their textual responses to an open-ended survey
2016
International audience; Over the past 20 years, the word "minerality" has been increasingly used in the description of wines. However, a precise definition of the concept of minerality appears to be inexistent, and no consensual meaning, even among wine professionals, can be identified. Although this word usage seems to spread out from wine professionals to consumers, research on what consumers assume about minerality is scarce. This paper aims to study the various concepts about minerality held-by consumers by using an open-ended questionnaire.A total of 1697 French-speaking consumers responded to an, online survey and their free answers were analysed using statistical textual methods. The…
Flavour: From food to perception
2016
Revue; This book will cover all aspects of flavour perception, including aroma, taste and the role of the trigeminal nerve, from the general composition of food to the perception at the peri-receptor and central level. This book will answer to a growing need for multidisciplinary approaches to better understand the mechanisms involved in flavour perception.The book presents the bases of anatomy of sensory perception. It will provide the requisite basic knowledge on the molecules responsible for flavour perception, on their release from the food matrix during the eating process in order to reach the chemosensory receptors, and on their retention and release from and transformation by bodily …
Should I use touchscreen tablets rather than computers and mice in TDS trials?
2016
International audience; Internet technologies are increasingly used as tools in sensory analysis. Thus, it would be a natural step forward for sensory science to move beyond the laboratory, into people's homes. Therefore, working with consumer IT devices like touchscreen tablets in sensory science should be taken into consideration. Working with the intuitive concept of dominance, Temporal Dominance of Sensations (TDS) requires a non-analytical answer from the subject. Using a touchscreen tablet instead of a classic mouse could reduce the cognitive load and favor a more instinctive answer. Indeed, it was proven that touch interaction is natural and efficient, and that finger pointing is fas…
Experiences from a wearable-mobile acquisition system for ambulatory assessment of diet and activity
2017
Public health trends are currently monitored and diagnosed based on large studies that often rely on pen-and-paper data methods that tend to require a large collection campaign. With the pervasiveness of smart-phones and -watches throughout the general population, we argue in this paper that such devices and their built-in sensors can be used to capture such data more accurately with less of an effort. We present a system that targets a pan-European and harmonised architecture, using smartphones and wrist-worn activity loggers to enable the collection of data to estimate sedentary behavior and physical activity, plus the consumption of sugar-sweetened beverages. We report on a unified pilot…
