Generation Of Aromas And Flavours

Consumer product acceptance and market success are dependent on the product's aroma/flavour. Flavours can be produced through chemical synthesis, microbial biocatalysis or by extraction from plants and animal sources. In recent times, chemical synthesis is not as desirable as this is not eco-friendly. So, in the food industry, natural ingredients are added to preparations for efficiency, softness or emotional appeal. Microbiology, bioengineering and biochemistry have enabled the elucidation of metabolic pathways; genetic engineering is expected to help in identifying metabolic blockages and creating novel high-yielding strains, while proteomics help in the application of analytical techniques. All these sciences, old and new, will lead to innovative ideas in the quest for better, sustainable and consumer-approved flavours and aromas.

Flavour is a critical aspect of food production and processing, requiring careful design, monitoring and testing in order to create an appealing food product. This book looks at flavour generation, flavour analysis and sensory perception of food flavour and how these techniques can be used in the food industry to create new and improve existing products. Part one covers established and emerging methods of characterising and analysing taste and aroma compounds. Part two looks at different factors in the generation of aroma. Finally, part three focuses on sensory analysis of food flavour. Covers the analysis and characterisation of aromas and taste compounds Examines how aromas can be created and predicted Reviews how different flavours are perceived

Food flavour technology is of key importance for the food industry.Increasingly, food products must comply with legal requirements andconform to consumer demands for “natural” products, butthe simple fact is that, if foods do not taste good, they will notbe consumed and any nutritional benefit will be lost. Thereis therefore keen interest throughout the world in the production,utilisation and analysis of flavours. The second edition of this successful book offers a broadintroduction to the formulation, origins, analysis and performanceof food flavours, updating the original chapters and addingvaluable new material that introduces some of the newermethodologies and recent advances. The creation of flavourings is the starting point for the book,outlining the methodology and constraints faced byflavourists. Further constraints are considered in a chapterdealing with international legislation. The origins of flavours aredescribed in three chapters covering thermal generation,biogeneration and natural sources, keeping in mind the adjustmentsthat manufacturers have had to make to their raw materials andprocesses to meet the demand for natural products whilst complyingwith cost issues. Delivery of flavours using encapsulation orthrough an understanding of the properties of the food matrix isdescribed in the next two chapters, and this section is followed bychapters describing the different ways to analyse flavours usinginstrumental, modelling and sensory techniques. The book is aimedat food scientists and technologists, ingredients suppliers,quality assurance personnel, analytical chemists andbiotechnologists.

In this book, major emphasis is placed on the effects of processing and food components upon the flavor of foods and beverages. Topics discussed include: roasting of peanuts; extrusion of cooking poultry; spray drying of natural flavor materials; cooking rates of foods; gamma radiation of packaging films; stir-frying of sautéd flavors; emulsification properties of egg yolk and lupin proteins; the interaction of flavor compounds with flour, starch, and polysaccharides; factors affecting development of flavor in whisky, wines, fermented products, alcohol precursors, and model food systems; applications of enzymes for production of flavor in fish, lobster and pork; and the development and application of analytical methods for isolation and identification of volatile compounds and flavors from a variety of food products. Information presented in this book will be useful to chemists, scientists, and technologists working in flavor chemistry, food product research and development, and food quality control.

Throughout history, human beings have sought ways to enhance the flavor of the foods they eat. In the 21st century, biotechnology plays an important role in the flavor improvement of many types of foods. This book covers many of the biotechnological approaches currently being applied to flavor enhancement. The contribution of microbial metabolism to flavor development in fermented beverages and dairy products has been exploited for thousands of years, but the recent availability of whole genome sequences of the yeasts and bacteria involved in these processes is stimulating targeted approaches to flavor enhancement. Chapters discuss recent developments in the flavor modification of wine, beer, and dairy products through the manipulation of the microbial species involved. Biotechnological approaches to the production of specific flavor molecules in microbes and plant tissue cultures, and the challenges that have been encountered, are also covered, along with the metabolic engineering of food crops for flavor enhancement - also a current area of research. Biotechnology is also being applied to crop breeding through marker-assisted selection for important traits, including flavor, and the book looks at the application of the biotechnological approach to breeding for enhanced flavor in rice, apple, and basil. These techniques are subject to governmental regulation, and this is addressed in a dedicated chapter. This updated second edition features five brand new chapters, and the topics covered in the book will be of interest to those in the flavor and food industries as well as to academic researchers interested in flavors.

Food flavor, appearance, and texture are the sensory properties that influence food acceptance, and among these, flavor is usually the decisive factor for the choice of a particular product. Food Flavors: Chemical, Sensory, and Technological Properties explores the main aspects of food flavors and provides a starting point for further study in focused areas. Topics discussed include: The nature of food odorants and tastants and the way they are perceived by the human olfactory system Basic anatomy and physiology of sensory systems involved in flavor sensation, olfactory pathways, and interactions between olfactory and gustatory stimuli The fundamentals of flavor compounds formation based on their main precursors (lipids, amino acids, and carbohydrates) Technological issues related to flavor compounds Physicochemical characteristics of aroma compounds and the main factors that influence aroma binding and release in foods Safety and regulatory aspects of flavorings used in foods Flavors of essential oils and spices, cheeses, red meat, wine, and bread and bakery products Food taints and off-flavors Analytical approaches to characterize food flavors The book also explores the latest technology in artificial olfaction systems with a chapter on the main physical and chemical features of these sensors. Bringing together the combined experience of a host of international experts, the book provides insight into the fundamentals of food flavors and explores the latest advances in flavor analysis.

Thermal processes play an important role in imparting desirable aromas to food which might otherwise have very bland flavors. In this new volume, internationally recognized experts in flavor chemistry present the latest research in analytical methodology, lipid-derived aromas, mechanistic studies, generation of selected aromas, generation of meat aromas, and extrusion and microwave processing foods. In addition, historical perspectives and regulatory viewpoints are included.
