Instrumental Methods in Food Analysis is aimed at graduate students in the science, technology and engineering of food and nutrition who have completed an advanced course in food analysis. The book is designed to fit in with one or more such courses, as it covers the whole range of methods applied to food analysis, including chromatographic techniques (HPLC and GC), spectroscopic techniques (AA and ICP), electroanalytical and electrophoresis techniques. No analysis can be made without appropriate sample preparation and in view of the present economic climate, the search for new ways to prepare samples is becoming increasingly important. Guided by the need for environmentally-friendly technologies, the editors chose two, relatively new techniques, the microwave-assisted processes (MAPTM (Chapter 10) and supercritical fluid extraction (Chapter 11). Features of this book: - is one the few academic books on food analysis specifically designed for a one semester or one year course -it contains updated information - the coverage gives a good balance between theory, and applications of techniques to various food commodities. The chapters are divided into two distinct sections: the first is a description of the basic theory regarding the technique and the second is dedicated to a description of examples to which the reader can relate in his/her daily work.

Methods in Food Analysis Applied to Food Products deals with the principles and the acquired tools of food analysis, emphasizing fruit and vegetable products. The book explains the suitability and limitations of the analytical procedures used for food products, from polarimetry and saccharimetry to colorimetry, spectrophotometry, viscosimetry, acidimetry, and alcoholometry. This volume is organized into 20 chapters and begins with an overview of sampling and preparation and preservation of sample. Under the physical methods, the principles of the more common procedures are discussed together with their application to the analysis of fruit and vegetable products. A brief account of the nature of the products is included. In presenting the chemical methods, the salient chemical properties of the constituent are first considered, focusing on those properties used in analysis, which is then followed by an outline of the chemistry of several of the available methods. Finally a detailed description of one of the methods, usually as applied to fruit and vegetable products, is explained. Some references to microanalytical, bioassay and bacteriological procedures are made. This book is intended for food technologists, chemists, and manufacturers; students; and researchers involved in quantitative analyses; organic and inorganic chemistry; and bacteriology.

Advances in instrumentation and applied instrumental analysis methods have allowed scientists concerned with food and beverage quality, labeling, compliance, and safety to meet ever increasing analytical demands. Texts dealing with instrumental analysis alone are usually organized by the techniques without regard to applications. The biannual review issue of Analytical Chemistry under the topic of Food Analysis is organized by the analyte such as N and protein, carbohydrate, inorganics, enzymes, flavor and odor, color, lipids, and vitamins. Under 'flavor and odor' the subdivisions are not along the lines of the analyte but the matrix (e.g. wine, meat, dairy, fruit) in which the analyte is being determined. In "Instrumentation in Food and Beverage Analysis" the reader is referred to a list of 72 entries entitled "Instrumentation and Instrumental Techniques" among which molecular spectroscopy, chromatographic and other sophisticated separations in addition to hyphenated techniques such as GS-Mass spectrometry. A few of the entries appear under a chapter named for the technique. Most of the analytical techniques used for determination, separations and sample work prior to determination are treated in the context of an analytical method for a specific analyte in a particular food or beverage matrix with which the author has a professional familiarity, dedication, and authority. Since, in food analysis in particular, it is usually the food matrix that presents the research analytical chemist involved with method development the greatest challenge.

This fifth edition provides information on techniques needed to analyze foods for chemical and physical properties. The book is ideal for undergraduate courses in food analysis and is also an invaluable reference to professionals in the food industry. General information chapters on regulations, labeling, sampling, and data handling provide background information for chapters on specific methods to determine chemical composition and characteristics, physical properties, and objectionable matter and constituents. Methods of analysis covered include information on the basic principles, advantages, limitations, and applications. Sections on spectroscopy and chromatography along with chapters on techniques such as immunoassays, thermal analysis, and microscopy from the perspective of their use in food analysis have been expanded. Instructors who adopt the textbook can contact the editor for access to a website with related teaching materials.

Food laws were fIrst introduced in 1860 when an Act for Preventing the Adulteration of Articles of Food or Drink was passed in the UK. This was followed by the Sale of Food Act in 1875, also in the UK, and later, in the USA, by the Food and Drugs Act of 1906. These early laws were basically designed to protect consumers against unscrupulous adulteration of foods and to safeguard consumers against the use of chemical preservatives potentially harmful to health. Subsequent laws, introduced over the course of the ensuing century by various countries and organisations, have encompassed the features of the early laws but have been far wider reaching to include legislation relating to, for example, specifIc food products, specifIc ingredients and specifIc uses. Conforming to the requirements set out in many of these laws and guidelines requires the chemical and physical analysis of foods. This may involve qualitative analysis in the detection of illegal food components such as certain colourings or, more commonly, the quantitative estimation of both major and minor food constituents. This quantitative analysis of foods plays an important role not only in obtaining the required information for the purposes of nutritional labelling but also in ensuring that foods conform to desired flavour and texture quality attributes. This book outlines the range oftechniques available to the food analyst and the theories underlying the more commonly used analytical methods in food studies.

With diet, health, and food safety news making headlines on a regular basis, the ability to separate, identify, and analyze the nutrients, additives, and toxicological compounds found in food and food components is more important than ever. This requires proper training in the application of best methods, as well as efforts to improve existing methods to meet analytical needs. Advances in instrumentation and applied instrumental analysis methods have allowed scientists concerned with food and beverage quality, labeling, compliance, and safety to meet these ever-increasing analytical demands. This updated edition of Methods of Analysis of Food Components and Additives covers recent advances as well as established methods in a concise guide, presenting detailed explanations of techniques for analysis of food components and additives. Written by leading scientists, many of whom personally developed or refined the techniques, this reference focuses primarily on methods of food analysis and novel analysis instruments. It provides readers with a survey of modern analytical instruments and methods for the analysis of food components, additives, and contaminants. Each chapter summarizes key findings on novel analysis methods, including the identification, speciation, and determination of components in raw materials and food products. The text describes the component or additive that can be analyzed, explains how it works, and then offers examples of applications. This reference covers selection of techniques, statistical assessments, analysis of drinking water, and rapid microbiological techniques. It also describes the application of chemical, physical, microbiological, sensorial, and instrumental novel analysis to food components and additives, including proteins, peptides, lipids, vitamins, carotenoids, chlorophylls, and food allergens, as well as genetically modified components, pesticide residues, pollutants, chemical preservatives, and radioactive components in foods. The Second Edition contains three valuable new chapters on analytical quality assurance, the analysis of carbohydrates, and natural toxins in foods, along with updates in the remaining chapters, numerous examples, and many new figures.
