Food Flavours


Book Description

How does the nose know what it smells? How do we taste foods? What gives foods their characteristic flavours? How do the methods of food preparation and processing change the flavours of foods? Food Flavours answers these questions and much more, in a clear and understandable manner, describing the composition of flavour compounds and the contributions they make to our sensory experiences. The book begins with the chemical reactions by which chemical compounds develop in plants, and continues through the processing and preparation of foods. It then turns to our chemical sensory systems to describe the recognition and neural processing of these compounds in the nervous system, and the reactions that we have to flavours. The way that chemical qualities give foods their characteristic flavours, and the ways various methods of food preparation and preservation affect those compounds and the resulting flavours are dealt with in detail, both from a chemical and a biological aspect. Throughout, Food Flavours provides special in-depth coverage of taste/odour physiology, and it contains a unique chapter providing a learning and problem-solving technique that will prove invaluable to students in all areas of food science, as well as in biological, organic and analytical chemistry, and will be a good addition to any food technologist's bookshelf.




Food Flavour Technology


Book Description

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.




Flavour Development, Analysis and Perception in Food and Beverages


Book Description

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




Generation of Aromas and Flavours


Book Description

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.




Taints and Off-Flavours in Foods


Book Description

Off-flavours and taints are defined as unpleasant odours or tastes, the first resulting from the natural deterioration of a food, the second from its contamination by some other chemical. Both are major problems for the food industry. With its distinguished editor and international team of contributors, this important collection describes some of the most important causes of taints and off-flavours, how they can be identified and dealt with.The book begins with chapters on sensory and instrumental methods for detecting and analysing taints and off-flavours in food. There are chapters on two of the most common causes of taints: packaging and residues from cleaning and disinfection. A number of chapters discuss the various causes of off-flavours, from those caused by microbial action and oxidation to those caused by the Maillard reaction and interactions between food components.With its authoritative coverage, Taints and off-flavours in food is a standard work for the food industry. - Describes some of the most important causes of taints and off-flavours in food and outlines how they can be identified and dealt with - Reviews the major causes of taints and off-flavours, from oxidative rancidity and microbiologically-derived off-flavours, to packaging materials as a source of taints - Discusses the range of techniques for detecting taints and off-flavours, from sensory analysis to instrumental techniques, including the development of new rapid, on-line sensors




The Flavor Matrix


Book Description

One of Smithsonian Magazine's Ten Best Food Books of the Year A revolutionary new guide to pairing ingredients, based on a famous chef's groundbreaking research into the chemical basis of flavor As an instructor at one of the world's top culinary schools, James Briscione thought he knew how to mix and match ingredients. Then he met IBM Watson. Working with the supercomputer to turn big data into delicious recipes, Briscione realized that he (like most chefs) knew next to nothing about why different foods taste good together. That epiphany launched him on a quest to understand the molecular basis of flavor--and it led, in time, to The Flavor Matrix. A groundbreaking ingredient-pairing guide, The Flavor Matrix shows how science can unlock unheard-of possibilities for combining foods into astonishingly inventive dishes. Briscione distills chemical analyses of different ingredients into easy-to-use infographics, and presents mind-blowing recipes that he's created with them. The result of intensive research and incredible creativity in the kitchen, The Flavor Matrix is a must-have for home cooks and professional chefs alike: the only flavor-pairing manual anyone will ever need.

In Defense of Processed Food


Book Description

It has become popular to blame the American obesity epidemic and many other health-related problems on processed food. Many of these criticisms are valid for some processed-food items, but many statements are overgeneralizations that unfairly target a wide range products that contribute to our health and well-being. In addition, many of the proposed dangers allegedly posed by eating processed food are exaggerations based on highly selective views of experimental studies. We crave simple answers to our questions about food, but the science behind the proclamations of food pundits is not nearly as clear as they would have you believe. This book presents a more nuanced view of the benefits and limitations of food processing and exposes some of the tricks both Big Food and its critics use to manipulate us to adopt their point of view. Food is a source of enjoyment, a part of our cultural heritage, a vital ingredient in maintaining health, and an expression of personal choice. We need to make those choices based on credible information and not be beguiled by the sophisticated marketing tools of Big Food nor the ideological appeals and gut feelings of self-appointed food gurus who have little or no background in nutrition.
