Analysis of Taste and Aroma


Book Description

The series Molecular Methods of Plant Analysis launches the former 'Modern Methods' into the 'molecular' era with this volume on "Taste and Aroma". Analysis of the plant components interacting with these two senses, so important for the very survival of human beings and, in more recent times, the key to their enjoyment of life as well, is presented with examples of the use of molecular approaches. These include DNA microarrays, antisense technology and RNA gel blot analysis.Some recent advances in plant analysis technology embrace amongst others the use of electroantennography in the detection of physiologically important flower volatiles. An introductory chapter explains what we know about the molecular biology of human taste and aroma receptors, as this has implications for the analysis of plant components interacting with these receptors. As the first volume in the molecular series, this book lays the foundation for others to come.




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




Sensory-Directed Flavor Analysis


Book Description

Today, flavor chemists can generate copious amounts of data in a short time with relatively little effort using automated solid phase micro-extraction, Gerstel-Twister and other extraction techniques in combination with gas chromatographic (GC) analysis. However, more data does not necessarily mean better understanding. In fact, the ability to extr




Flavor Analysis


Book Description

Filled with practical examples, this volume illustrates innovative flavor analysis techniques used by today's leaders in food chemistry. It covers flavor analysis for apples, beef, citrus, coffee, cheese, extruded pet foods, fungi, milk, and Maillard reaction systems, and the researchers come from throughout the industrialized world. Eleven of the chapters illustrate techniques for isolating volatile compounds from complex food matrices, including micro-scale liquid-liquid extraction, headspace sampling, solid phase microextraction, supercritical fluid extraction, and thermo desorption. The chapters devoted to analytical characterization include analyses of Amadori compounds, sulfur compounds, chiral compounds, coumarins and psoralens, flavor precursors, and natural products by GC, GC-MS, HPLC-MS, CCC (countercurrent chromatography), and GC-IRMS (gas chromatography isotope ration mass spectrometry). The final section covers sensory characterization and describes examples using the gas chromatography-olfactory techniques OSME and AEDA as well as the new GC-SOMMSA (selective odorant measurement by multisensor array).




Flavor, Fragrance, and Odor Analysis


Book Description

Written from a practical, problem-solving perspective, this reference explores advances in mass spectrometry, sample preparation, gas chromatography (GC)-olfactometry, and electronic-nose technology for food, cosmetic, and pharmaceutical applications. The book discusses the chemical structures of key flavor and fragrance compounds and contains nume




Flavour in Food


Book Description

Annotation The flavour of a food is one of its most important qualities. Edited by two leading authorities in the field, and with a distinguished international team of contributors, this important collection summarises the wealth of recent research on how flavour develops in food and is then perceived by the consumer. The first part of the book reviews ways of measuring flavour. Part 2 looks at the ways flavour is retained and released in food. It considers the way flavour is retained in particular food matrices, how flavour is released during the process of eating, and the range of influences governing how flavour is perceived by the consumer. Flavour in food guides the reader through a complex subject and provides the essential foundation in both understanding and controlling food flavour. CONTENTS Part 1 Characterisation of aroma compounds: Choosing the correct analytical technique; Gaschromatography olfactometry; Human perception of taste compounds; Sensory analysis of food flavour; Matching sensory and instrumental data. Part 2 Flavour retention and release in the food matrix: Flavour binding; Emulsion-flavour interactions; Carbohydrate-flavour interactions; Modelling aroma interactions; The process of flavour release; Odourtaste interactions in flavour perception; Modulation of taste by flavour preferences.




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.




Nutritional Needs in Cold and High-Altitude Environments


Book Description

This book reviews the research pertaining to nutrient requirements for working in cold or in high-altitude environments and states recommendations regarding the application of this information to military operational rations. It addresses whether, aside from increased energy demands, cold or high-altitude environments elicit an increased demand or requirement for specific nutrients, and whether performance in cold or high-altitude environments can be enhanced by the provision of increased amounts of specific nutrients.




How Flavor Works


Book Description

Taste is the number one driving force in the decision to purchase a food product and food consumption is the most critical function for living organisms to obtain the energy and resources essential to their vitality. Flavor and aroma are therefore universally important concepts: intrinsic to human well-being and pleasure, and of huge significance for the multi-trillion dollar global food business. How Flavor Works: the Science of Taste and Aroma offers a fascinating and accessible primer on the concepts of flavor science for all who have an interest in food and related topics. Professionals and students of food science and technology who do not already specialize in flavor science will find it a valuable reference on a topic crucial to how consumers perceive and enjoy food products. In this regard, it will also be of interest to product developers, marketers and food processors. Other readers with a professional (eg culinary and food service) or personal interest in food will also find the book interesting as it provides a user-friendly account of the mechanisms of flavor and aroma which will provide new insights into their craft.
