Book Description
Wine is a widely consumed beverage due to its unique and pleasant sensory properties. Wine is composed of more than one thousand chemical compounds (e.g., alcohols, esters, acids, terpenoids, phenolic compounds, flavonoids, anthocyanins, minerals, and vitamins, among others) resulting from several chemical and biochemical processes. Microextraction techniques in tandem with high-resolution analytical instruments have been applied by wine researchers to expand the knowledge of wine’s chemical composition with the purposes of improving wine quality, supporting winemaker decisions related to the winemaking process, and guaranteeing the authenticity of wine. As a result, we proposed “Chemical/Instrumental Approaches to the Evaluation of Wine Chemistry” as a topic for a Special Issue in Molecules. This Special Issue aims to provide an update on state-of-the-art extraction procedures (e.g., solid-phase microextraction (SPME)) and analytical tools (e.g., nuclear magnetic resonance (NMR), inductively coupled plasma mass spectrometry (ICP-MS), ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS)), emphasizing their use as suitable platforms for the establishment of the chemical composition of wine (volatomic profile, antioxidants, phenolic pattern, and elemental composition, among others). Information related to wine sensorial properties, contaminants, authenticity, and chemometric tools used for data treatment are described in this Issue.

Book Description
Instrumental measurements of the sensory quality of food and drink are of growing importance in both complementing data provided by sensory panels and in providing valuable data in situations in which the use of human subjects is not feasible. Instrumental assessment of food sensory quality reviews the range and use of instrumental methods for measuring sensory quality.After an introductory chapter, part one goes on to explore the principles and practice of the assessment and analysis of food appearance, flavour, texture and viscosity. Part two reviews advances in methods for instrumental assessment of food sensory quality and includes chapters on food colour measurement using computer vision, gas chromatography-olfactometry (GC-O), electronic noses and tongues for in vivo food flavour measurement, and non-destructive methods for food texture assessment. Further chapters highlight in-mouth measurement of food quality and emerging flavour analysis methods for food authentication. Finally, chapters in part three focus on the instrumental assessment of the sensory quality of particular foods and beverages including meat, poultry and fish, baked goods, dry crisp products, dairy products, and fruit and vegetables. The instrumental assessment of the sensory quality of wine, beer, and juices is also discussed.Instrumental assessment of food sensory quality is a comprehensive technical resource for quality managers and research and development personnel in the food industry and researchers in academia interested in instrumental food quality measurement. - Reviews the range and use of instrumental methods for measuring sensory quality - Explores the principles and practice of the assessment and analysis of food appearance, flavour, texture and viscosity - Reviews advances in methods for instrumental assessment of food sensory quality

Book Description
Modern Methods of Plant Analysis When the handbook Modern Methods of Plant Analysis was first introduced in 1954 the considerations were: 1. the dependence of scientific progress in biology on the improvement of existing and the introduction of new methods; 2. the difficulty in finding many new analytical methods in specialized journals which are normally not accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently so compact, or even sometimes so incomplete that it is difficult to reproduce experiments. These considerations still stand today. The series was highly successful, seven volumes appearing between 1956 and 1964. Since there is still today a demand for the old series, the publisher has decided to resume publication of Modern Methods of Plant Analysis. It is hoped that the New Series will be just as acceptable to those working in plant sciences and related fields as the early volumes undoubtedly were. It is difficult to single out the major reasons for success of any publication, but we believe that the methods published in the first series were up-to-date at the time and presented in a way that made description, as applied to plant material, complete in itself with little need to consult other publications. Contributing authors have attempted to follow these guidelines in this New Series of volumes.

Book Description
Intuitively organized textbook aligned to common analytical instrumentation courses for undergraduate students Through an analytical approach, Essential Methods of Instrumental Analysis provides an expansive overview of common instruments and methods and their applications for undergraduate students, integrating experimental protocols with real result examples to deliver a well-rounded understanding of the inner workings of the instruments and enabling students to evaluate the success of their experiments and create scientific figures. In addition to detailed coverage of specific instruments, the book discusses analytical laboratory practices, instrument maintenance, statistics, and real-world lab experiments with previous student results. Each analytical method section includes extensive sample preparation information, rather than a simple stand-alone chapter offering generic discussions not connected to specific methods. This book conveniently organizes content by analyte class (inorganic and organic) in a way that is intuitive to a student and aligned with relevant courses. Ancillaries including .mp4 videos, instructor PowerPoint slides, and animations are included on a companion website. Written by an experienced professor and tested and refined over years in his courses since 2008, Essential Methods of Instrumental Analysis includes information on sample topics such as: Proper laboratory protocols for analytical instrumentation, covering chemical reagents, glassware, calibration techniques, and figures of merit Optical physics, covering the interaction of electromagnetic radiation with instrument components and sample molecules, relaxation processes, reflection, diffraction, dispersion, and refraction Flame atomic absorption and flame emission spectrometry, covering optical radiation sources, mirrors, choppers, burner heads, and doppler broadening Gas and liquid chromatography, covering gaseous, liquid, soil-sediment, and biological samples, analyte recovery, chromatography theory, injectors, columns and ovens, common detectors, and mass spectrometers Focusing on contrasts and comparisons across multiple types of instruments in a way distinct from similar texts, Essential Methods of Instrumental Analysis is an essential textbook for students in advanced undergraduate courses in related programs of study.

Book Description
Forty years of progress in the fields of gas chromatography and data collection have culminated in flavoromics. This is a combination of chemometrics and metabolomics. Essentially, it is the non-targeted way of rapidly collecting a significant amount of data from a wide range of sample populations and using the data to study complicated topics. Now that we have the required tools, we can carry out high-throughput trace investigations that incorporate both gustatory and olfactory signals. Flavoromics: An Integrated Approach to Flavor and Sensory Assessment describes the tools to do high-throughput, trace analyses that represent both taste and olfaction stimuli. It explains how today's single sample research will generate thousands of data points, which are loaded into sophisticated statistical analysis algorithms to establish what stimuli are responsible for flavor. This cutting-edge equipment will enable us to create flavorings and perfumes that are more realistic and superior. Key Features: Includes a detailed section on data handling/mining Section 4 describes a broad overview of different food matrices Points out the integration of flavoromics with advanced separation methods, data management, statistical modeling, and variable selection This book represents a revolutionary tool waiting to help make better, truer to life flavorings and fragrances.

Book Description
This Symposium on Modern Methods of Food Analysis was the sev enth in a series of basic symposia, begun in 1976, on topics of major importance to food scientists and food technologists. The Symposium, sponsored jointly by the Institute of Food Technologists and the In ternational Union of Food Science and Technology, was held June 17 and 18, 1983, in New Orleans immediately prior to the 43rd annual 1FT meeting. Like the other six basic symposia, the program brought together outstanding speakers, from biochemistry, chemistry, food science, microbiology and nutrition, who are at the cutting edge of their specialty, and provided a setting where they could interact with each other and with the participants. The Symposium and this book are dedicated to the memory of George F. Stewart (1908-1982) who made so many important contributions to the field of food science, including that of food analysis. Bernard S. Schweigert has documented George F. Stewart's contributions in the Dedication of this book.

Book Description
This text is designed to acquaint the reader with the commonly used procedures of juice and wine analysis as they are generally practiced in the industry, and as they are taught in the Department of Enology at California State University, Fresno. It is assumed that the reader has a basic preparation in the fields of chemistry and microbiology. In developing material for this text, the authors have emphasized analyses as they would be carried out in a production laboratory. Realizing that different laboratories have different analytical capabilities, personnel as well as equip ment, we have in many instances provided several different approaches to the same analysis. Throughout this book we have attempted to give special attention to practical considerations and the importance of these analyses in the total spectrum of winery operations. We hope the book's format will satisfy the inter ests oflaboratory personnel as well as winemakers. The process of making wine involves a series of concerns for the winemaker and staff of a winery. The first concerns are viticultural. Upon arrival of the fruit, its quality is assessed, grapes are processed and fermentation is begun. Almost immediately, and in many instances simultaneously, chemical and microbiological stability of the young and/or aging wine become important. Finally, problems do occur on occasion, and a number of what may be consid ered remedial techniques can be employed to produce an acceptable product.
