Flavour Science
The aim of this study was to quantify the effects of sugar and CO2 contents on the sensory and physicochemical properties of mint-flavored carbonated beverages, combining sensory and instrumental dynamic methods. Sensory results revealed that the presence of CO2 increased aroma perception regardless of the sugar content. In agreement with volatility parameters, in vivo measurements showed that carbonated drinks released more aroma compounds in the nose space than non-carbonated ones. Sugar content increased aroma perception only in the case of non-carbonated beverages, highlighting the existence of sensory interactions between sweet and aroma perceptions. For carbonated beverages, sugar content had an impact on aroma release, but not on aroma perception.
Flavour Science
An integrated approach combining sensory analysis and physicochemistry was used to investigate the impact of swallowing on aroma release and perception. A panel of 10 people evaluated the dynamics of aroma perception during the consumption of a commercial flavored vodka, using two protocols (spitting out or swallowing the product) and the temporal dominance of sensations method. Aroma release in their nasal cavity was simultaneously measured by proton transfer reaction mass spectrometry. The swallowing of the product resulted in more complex perceptions, but decreased the dominance rates of aromatic attributes. Ethanol perception also had a high impact when the product was swallowed.
Flavour Science
Flavor science is continually evolving. Remaining current with the latest research and establishing a broad and sound understanding of the major developments and breakthroughs can be a challenge. The Weurman Flavour Research Symposium has long been regarded as the premier professional meeting focused on the science of flavor. Flavour Science, an extensive review of the most recent symposium, presents the latest in flavor research, enriching the chemistry-based vision of most flavorists and flavor chemists with understanding from a broad range of fields, including human physiology, ethology, psychophysics, genetics, bioinformatics or metabolomics. This book is ideal for all flavor scientists, food chemists and sensory scientists and has a strong audience among enologists as well. - Focuses on the rapidly changing field of flavor science - Includes the latest information on the physiology, chemistry and measurement of flavor - Presents practical information on the flavor industry and emerging trends
Texture et flaveur des aliments
Quelles sont les molécules responsables de l'arôme et de la saveur des aliments ? Comment ces molécules sont-elles libérées pour accéder aux récepteurs e sensoriels et être perçues ? Comment la texture de l'aliment influence-t-elle la perception de l'odeur et de la saveur ? Ce livre rassemble les principaux résultats de recherches menées dans le domaine de l'agroalimentaire, dans les sciences des aliments et dans le comportement du consommateur. Il présente les bases nécessaires pour comprendre les mécanismes mis en jeu dans la perception des odeurs et des saveurs dans des aliments de natures différentes. Pour cela, il reprend, de manière simple et accessible, les bases de la...
Flavour
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 fluids of the oral and nasal cavities. It will also bring current knowledge on the multimodal interactions. This book will also cover the recent evolution in flavour science: characterisation of molecules, interaction with food matrix and more recently, physic-chemical and physiological and events during oral processing increasingly considered.
Sample Preparation in Metabolomics
Metabolomics is increasingly being used to explore the dynamic responses of living systems in biochemical research. The complexity of the metabolome is outstanding, requiring the use of complementary analytical platforms and methods for its quantitative or qualitative profiling. In alignment with the selected analytical approach and the study aim, sample collection and preparation are critical steps that must be carefully selected and optimized to generate high-quality metabolomic data. This book showcases some of the most recent developments in the field of sample preparation for metabolomics studies. Novel technologies presented include electromembrane extraction of polar metabolites from plasma samples and guidelines for the preparation of biospecimens for the analysis with high-resolution μ magic-angle spinning nuclear magnetic resonance (HR-μMAS NMR). In the following chapters, the spotlight is on sample preparation approaches that have been optimized for diverse bioanalytical applications, including the analysis of cell lines, bacteria, single spheroids, extracellular vesicles, human milk, plant natural products and forest trees.
ECAI 2014
The role of artificial intelligence (AI) applications in fields as diverse as medicine, economics, linguistics, logical analysis and industry continues to grow in scope and importance. AI has become integral to the effective functioning of much of the technical infrastructure we all now take for granted as part of our daily lives. This book presents the papers from the 21st biennial European Conference on Artificial Intelligence, ECAI 2014, held in Prague, Czech Republic, in August 2014. The ECAI conference remains Europe's principal opportunity for researchers and practitioners of Artificial Intelligence to gather and to discuss the latest trends and challenges in all subfields of AI, as we...
