Instrumental Methods in Food Analysis by J.R.J. Paré,J.M.R. Bélanger Pdf

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.

Instrumental Methods in Food and Beverage Analysis by D.L.B. Wetzel,G. Charalambous Pdf

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.

Application of Analytical Chemistry to Foods and Food Technology by Daniele Naviglio,Monica Gallo Pdf

The application of analytical chemistry to the food sector allows the determination of the chemical composition of foods and the properties of their constituents, contributing to the definition of their nutritional and commodity value. Furthermore, it is possible to study the chemical modifications that food constituents undergo as a result of the treatments they undergo (food technology). Food analysis, therefore, allows us not only to determine the quality of a product or its nutritional value, but also to reveal adulterations and identify the presence of xenobiotic substances potentially harmful to human health. Furthermore, some foods, especially those of plant origin, contain numerous substances with beneficial effects on health. While these functional compounds can be obtained from a correct diet, they can also be extracted from food matrices for the formulation of nutraceutical products or added to foods by technological or biotechnological means for the production of functional foods. On the other hand, the enormous growth of the food industry over the last 50 years has broadened the field of application of analytical chemistry to encompass not only food but also food technology, which is fundamental for increasing the production of all types of food.

Spectroscopic Methods in Food Analysis by Adriana S. Franca,Leo M.L. Nollet Pdf

Given the inherent complexity of food products, most instrumental techniques employed for quality and authenticity evaluation (e.g., chromatographic methods) are time demanding, expensive, and involve a considerable amount of manual labor. Therefore, there has been an increasing interest in simpler, faster, and reliable analytical methods for assessing food quality attributes. Spectroscopic Methods in Food Analysis presents the basic concepts of spectroscopic methods, together with a discussion on the most important applications in food analysis. The determination of product quality and authenticity and the detection of adulteration are major issues in the food industry, causing concern among consumers and special attention among food manufacturers. As such, this book explains why spectroscopic methods have been extensively employed to the analysis of food products as they often require minimal or no sample preparation, provide rapid and on-line analysis, and have the potential to run multiple tests on a single sample (i.e., non-destructive). This book consists of concepts related to food quality and authenticity, that are quite broad, given the different demands of the manufacturer, the consumer, the surveillance and the legislative bodies that ultimately provide healthy and safe products.

Applications of Instrumental Methods for Food and Food By-Products Analysis by Agata Gorska Pdf

The analysis of food and food by-products is a particularly important topic dealing with the development and application of various analytical procedures and methods determining the properties and safety of food and food constituents. It is an important tool not only for defining food quality but also for supporting the investigation of new food products and technologies. The continuous development of methodology and access to modern research equipment enable detailed research on the composition, structure, physicochemical properties, thermal characteristics, and stability of food products and, recently, also byproducts of the food industry, which are potentially a source of bioactive compounds and currently present little commercial value and are mostly disposed of as an industrial waste. It is imperative to identify the properties and potential applications of food by-products, which would fit in with current trends in circular ecology. Taking the aforementioned reasons into account, it is important to present procedures and instrumental analytical techniques and methods commonly used to analyze food and food processing byproducts and to discuss their application in food research to detect and characterize specific food components of significance to food science and technology, such as lipids, proteins, and carbohydrates.

Instrumental Analysis in the Biological Sciences by M. H. Gordon Pdf

Instrumental techniques of analysis have now moved from the confines of the chemistry laboratory to form an indispensable part of the analytical armoury of many workers involved in the biological sciences. It is now quite out of the question to considcr a laboratory dealing with the analysis of biological materials that is not equipped with an extensive range of instrumentation. Recent years have also seen a dramatic improvement in the ease with which such instruments can be used, and the quality and quantity of the analytical data that they can produce. This is due in no sm all part to the ubiquitous use of microprocessors and computers for instrumental control. However, under these circumstances there is areal danger of the analyst adopting a 'black box' mentality and not treating the analytical data produced in accordance with the limitations that may be inherent in the method used. Such a problem can only be overcome if the operator is fully aware of both the theoretical and instrumental constraints relevant to the technique in question. As the complexity and sheer volume of material in undergraduate courses increases, there is a tendency to reduce the amount of fundamental material that is taught prior to embarking on the more applied aspects. This is nowhere more apparent than in the teaching of instrumental techniques of analysis.
