This book was released on 2021-06-24 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food manufacturers, researchers and society in general are increasingly highly interested in the quality and origin of food products. Considering the complexity of the food chain in a globalized world — where many players are involved between production and consumption — fraudulent food manipulation and adulteration practices are increasingly easier to conduct without being detected. Generally, food adulteration is carried out to increase volume, to mask the presence of inferior quality components, and to replace authentic substances for the seller's economic gain. Analytical methodologies to guarantee food integrity and authenticity are therefore required.Chromatographic and Related Separation Techniques in Food Integrity and Authenticity — Volume A: Advances in Chromatographic Techniques addresses fraud prevention and the latest chromatographic and related separation analytical techniques to guarantee food integrity and authenticity by giving special attention to relevant authenticity issues in food production.Chromatographic and Related Separation Techniques in Food Integrity and Authenticity — Volume B: Relevant Applications addresses the relevant application of techniques to assess different food products' integrity and authenticity.

This book was released on 2013-04-17 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years several new instrumental techniques have been introduced for chromatographie separations. In addition, rapid developments in existing methods, such as preparative HPLC, have taken place. Despite these advances, how ever, a handbook covering the various preparative aspects ofthe new separation tech niques does not exist. This book is an attempt to fill the gap and to present a compila tion of modern separation techniques that will be useful for researchers faced with day-to-day preparative problems. Numerous examples of separations have been selected in order to show the possibilities (and also the limits) of each technique treated. These are often either applications from our own laboratory or else they reflect the approach we have been following for the isolation of natural products from plant sourees. Owing to the large number of published papers and the diversity of secondary plant constituents. an exhaustive survey of the literature has not been undertaken. We hope, however, that the examples selected will suggest to the reader which technique(s) and which conditions to choose for a particular isolation problem in the field of natural products. For invaluable help in the preparation of the manuscript for this book, we would like to thank Corinne Appolonia and Christine Marston. Lausanne, November 1985 K. Hostettmann M. Hostettmann A . . Marston Foreword Although not many people realize this, isolation and purification of biologically active materials is becoming increasingly crucial.

Available in PDF, EPUB and Kindle. Book excerpt: oCompilation and evaluation of the newest applications of chromatography for food science and technology oEnumeration of chromatographic methods and critical discussion of results This book presents a unique collection of up-to-date chromatographic methods for the separation and quantitative determination of carbohydrates, lipids, proteins, peptides, amino acids, vitamins, aroma and flavor compounds in a wide variety of foods and food products. Chromatography in Food Science and Technology presents a concise evaluation of existing chromatographic methods used for many food and food product macro and microcomponents. Chromatographic methods are compiled according to the character of the food components to be separated. The book's chapters deal separately with the different classes of food components, presenting both gas and liquid chromatographic methods used for their determination, and discussing the advantages and disadvantages of each. Unlike other references, Chromatography in Food Science and Technology is entirely devoted to the use of chromatography for food analysis, and focuses on practical, food-related examples. It treats the theoretical aspects of chromatography briefly, to the degree that the information helps the use and development of new analytical methods for the separation of any kind of food components.

Available in PDF, EPUB and Kindle. Book excerpt: Food products are very complex mixtures consisting of naturally occurring compounds and other substances, generally originating from technological processes, agrochemical treatments, or packaging materials. However, food is no longer just a biological necessity for survival. Society demands healthy and safe food, but it is also increasingly interested in other quality attributes more related to the origin of the food, the agricultural production processes used, the presence or not of functional compounds, etc. Improved methods for the determination of authenticity, standardization, and efficacy of nutritional properties in natural food products are required to guarantee their quality and for the growth and regulation of the market. Nowadays, liquid chromatography with ultraviolet detection, or coupled to mass spectrometry and high-resolution mass spectrometry, are among the most powerful techniques to address food safety issues and to guarantee food authenticity in order to prevent fraud. The aim of this book is to gather review articles and original research papers focused on the development of analytical techniques based on liquid chromatography for the analysis of food. This book is comprised of six valuable scientific contributions, including five original research manuscripts and one review article, dealing with the employment of liquid chromatography techniques for the characterization and analysis of feed and food, including fruits, extra virgin olive oils, confectionery oils, sparkling wines and soybeans.

Book excerpt: Chromatography is the collective term for a set of laboratory techniques for the separation of mixtures. It involves passing a mixture dissolved in a "mobile phase" through a stationary phase, which separates the analyte to be measured from other molecules in the mixture and allows it to be isolated. Chromatography may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for further use (and is thus a form of purification). Analytical chromatography is done normally with smaller amounts of material and is for measuring the relative proportions of analytes in a mixture. This new and important book gathers the latest research from around the globe in the study of chomatography and herein highlights such topics as: analysis of veterinary drugs using chromatographic techniques, liquid chromatography for the determination of mycotoxins in foods, chromatography in the research of phenolic secondary metabolites, and others.

This book was released on 2015 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for high-throughput separations in food and environmental research that are able to cope with the analysis of a large number of compounds in very complex matrices. Laboratories worldwide are now demanding fast and efficient analytical procedures with enough sensitivity, robustness, effectiveness and high resolution to be able to perform both qualitative and quantitative analysis while at the same time achieving cost-effective methodologies with reduced analysis times. Whereas the most common approach for solving many analytical problems has often been high-performance liquid chromatography (HPLC), the recent use of fast or ultra-fast chromatographic methods for environmental and food analysis has increased the overall sample throughput and laboratory efficiency without loss (and even with an improvement) in the resolution obtained by conventional HPLC systems.This book brings together researchers at the top of their field from across the world to discuss and analyze recent advances in fast liquid chromatography–mass spectrometry (LC–MS) methods for food and environmental analysis. It focuses on the development of the analytical method: sample preparation, chromatographic separation, mass spectrometry and, finally, confirmation and quantification aspects. These topics are addressed in three main parts. First, the most novel approaches to achieve fast and ultra-fast methods as well as the use of alternative and complementary stationary phases are described. In the second part, advances in fast LC–MS methods are addressed, focusing on novel treatment procedures coupled with LC–MS, new ionization sources, high-resolution mass spectrometry, and the problematic confirmation and quantification aspects in mass spectrometry. Finally, the third part is devoted to relevant LC–MS applications in food and environmental analysis and addresses the analysis of pesticides, mycotoxins, food packaging contaminants, perfluorinated compounds and polyphenolic compounds.This book brings together researchers working at the top of the field at universities and in industry from across the world to present the state-of-the-art in current research on food and environmental analysis. The scope of the book is intentionally broad and is aimed at worldwide analytical laboratories working in food and environmental applications as well as researchers in universities worldwide.

This book was released on 2013-03-08 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: The food analyst plays an important role in modern society. Stricter control over additives in food and concern about the effects of contamination of food by industrial and agricultural chemicals are among the developments which are leading to an increasing emphasis on detailed and accurate analysis of food. However. analysis of food is required for many reasons, including detection of toxic components, monitoring legislation, detecting adulteration, formulation of controlled diets, controlling formulation during product development and detecting changes in food during storage and processing. Foods comprise a complex mixture of components and food analysis requires efficient methods of separation with high sensitivity or specificity of detection. Although many food components are involatile or thermally labile and therefore not suitable for analysis by gas chromatography, other components are volatile and this technique is the preferred analytical method. Developments in methods of derivati zation, injector design and column technology have also extended the applicability of gas chromatography to the analysis of relatively involatile compounds.
