Analysis of Taste and Aroma

Analysis Of Taste And Aroma [Pdf/ePub] eBook

Analysis of Taste and Aroma by John F. Jackson,H.F. Linskens Book Resume:

Molecular Methods of Plant Analysis Concept of the Series The powerful recombinant DNA technology and related developments have had an enormous impact on molecular biology. Any treatment of plant analysis must make use of these new methods. Developments have been so fast and the methods so powerful that the editors of Modern Methods of Plant Analysis have now decided to rename the series Molecular Methods ofPlant Analysis. This will not change the general aims of the series, but best describes the thrust and content of the series as we go forward into the new millennium. This does not mean that all chapters a priori deal only with the methods of molecular biology,but rather that these methods are to be found in many chapters together with the more traditional methods of analysis which have seen recent advances. The numbering of the volumes of the series therefore continues on from 20, which is the most recently published volume under the title Modern Methods ofPlant Analysis. As indicated for previous volumes, the methods to be found in Molecular Methods ofPlantAnalysis are described critically,with hints as to their limitations, references to original papers and authors being given, and the chapters written so that there is little need to consult other texts to carry out the methods of analysis described. All authors have been chosen because of their special experience in handling plant material and/or their expertise with the methods described.

Sensory-Directed Flavor Analysis

Analysis Of Taste And Aroma [Pdf/ePub] eBook

Sensory-Directed Flavor Analysis by Ray Marsili Book Resume:

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 extract, isolate, and concentrate potential flavor-important chemicals from complex food systems has surpassed the ability to understand how the chemical data relates to flavor. Sensory-Directed Flavor Analysis helps chemists unlock the flavor secrets that may be hiding in their chromatograms by translating cold hard numbers into a better understanding of the sense of smell and taste. The author integrates the two disciplines of sensory science and analytical chemistry, encouraging sensory scientists to incorporate more analytical data while encouraging analytical chemists to include more sensory techniques. Using more ancillary techniques helps each discipline elucidate how various chemical constituents influence food flavor and appeal. The book discusses important enabling technologies and analytical methods including GC-olfactometry (GC-O), combination GC-O and multi-dimensional GC, the application of odor activity values (OAVs), and recombination studies, as well as solid-phase dynamic extraction and preseparation techniques. A broad array of applications, in addition to dozens of tables, graphs, gas chromatograms, and pictures, are included throughout the book. Highlighting the advantages and disadvantages and the appropriate circumstances for each method of analysis, Sensory-Directed Flavor Analysis offers flavor scientists an essential reference to deepen their understanding of the function of chemicals on the perception of taste.

Food Taints and Off-Flavours

Analysis Of Taste And Aroma [Pdf/ePub] eBook

Food Taints and Off-Flavours by M.J. Saxby Book Resume:

Contamination of food with extremely low levels of certain compounds can cause an unpleasant taste. This can result in the destruction of vast stocks of product, and very substantial financial losses to food companies. The concentration of the alien compound in the food can be so low that very sophisticated equipment is needed to identify the components and to determine its source. It is vital that every company involved in the production, distribution and sale of foodstuffs are fully aware of the ways in which contamination can accrue, how it can be avoided, and what steps need to be taken in the event that a problem does arise. This book provides the background information needed to recognize how food can become tainted, to draw up guidelines to prevent this contamination, and to plan the steps that should be taken in the event of an outbreak. The new edition has been extensively revised and updated and includes substantial new material on the formation of off flavors due to microbiological and enzymic action, and on sensory evaluation of taints and off flavors A new chapter on off flavors in alcoholic beverages has been added. Written primarily for industrial food technologists, this volume is also an essential reference source for workers in research and government institutions.

Food Flavours

Analysis Of Taste And Aroma [Pdf/ePub] eBook

Food Flavours by Carolyn Fisher,Thomas R. Scott Book Resume:

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.
