Due to its high sensitivity and selectivity, liquid chromatography–mass spectrometry (LC–MS) is a powerful technique. It is used for various applications, often involving the detection and identification of chemicals in a complex mixture. Ultra Performance Liquid Chromatography Mass Spectrometry: Evaluation and Applications in Food Analysis presents a unique collection of up-to-date UPLC-MS/MS methods for the separation and quantitative determination of components, contaminants, vitamins, and aroma and flavor compounds in a wide variety of foods and food products. The book begins with an overview of the history, principles, and advancement of chromatography. It discusses the use of UHPLC techniques in food metablomics, approaches for analysis of foodborne carcinogens, and details of UPLC-MS techniques used for the separation and determination of capsaicinoids. Chapters describe the analysis of contaminants in food, including pesticides, aflatoxin, perfluorochemicals, and acrylamide, as well as potentially carcinogenic heterocyclic amines in cooked foods. The book covers food analysis for beneficial compounds, such as the determination of folate, vitamin content analysis, applications for avocado metabolite studies, virgin olive oil component analysis, lactose determination in milk, and analysis of minor components of cocoa and phenolic compounds in fruits and vegetables. With contributions by experts in interdisciplinary fields, this reference offers practical information for readers in research and development, production, and routing analysis of foods and food products.

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.

For food scientists, high-performance liquid chromatography (HPLC) is a powerful tool for product composition testing and assuring product quality. Since the last edition of this volume was published, great strides have been made in HPLC analysis techniques-with particular attention given to miniaturization, automatization, and green chemistry. Tho

Among liquid chromatography methods, ion chromatography (IC) can be considered one of the most valuable analytical tools. This book covers the various applications of ion chromatography in food science, such as food quality control, food authentication and analysis of residues in food products. In addition, state-of-the-art instrumentation such as combustion IC, online eluent generation systems and capillary IC is also described.

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.

Liquid Chromatographic Analysis of Food and Beverages, Volume 2 focuses on the role and utilization of reversed-phase separation techniques in the food, agricultural, biochemical, biomedical, and clinical area. This book discusses the high pressure liquid chromatography; estimation of dextrose equivalent value of starch hydrolysates from liquid chromatographic profiles; and analysis of gluconic acid in botrytized wines. The HPLC of carbohydrate products; reducing sugar derivatization for ultraviolet absorption detection in HPLC analyses; and quantitative determination of dextromethorphan hydrobromide in cough remedies by high precision liquid chromatography are also elaborated. This text likewise discusses the separation of hop compounds by reverse-phase HPLC and analysis of polymethoxylated flavones in orange juice and fruit parts. This book is a good reference for food technologists and researchers conducting work on liquid chromatographic analysis of food and beverages.
