Book Description
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.

Book Description
Liquid Chromatographic Analysis of Food and Beverages, Volume 1 contains the proceedings of a Symposium on the Analysis of Foods and Beverages by HPLC, organized by the Flavor Subdivision of American Chemical Society and held in Honolulu, Hawaii, on April 1-6, 1979. The papers explore the applications of high-performance liquid chromatography (HPLC) to food and beverage analysis. Emphasis is on advances in technology and instrumentation as well as analytical results in a variety of contexts. This volume is comprised of 13 chapters and begins with a discussion on the use of spectroscopy in liquid chromatographic analysis of foods, with particular reference to the techniques and instrumentation required to obtain reliable qualitative data on components isolated via HPLC. The reader is then introduced to HPLC determination of naturally occurring capsaicins; Fast separation of amino acids using ion exchange chromatography; reversed phase HPLC for analyzing aflatoxins in foods and beverages via fluorescence detection; and the use of dual detectors for HPLC multivitamin analysis of citrus juices. High performance radial chromatography of aflatoxins and HPLC analysis of monosaccharides in avocado are also explored. This book will be of interest to students, chemists, food technologists, and those in the food and beverage industry.

Book Description
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.

Book Description
The Quality of Foods and Beverages, Volume II: Chemistry and Technology contains the proceedings of the second International Flavor Conference held in Athens, Greece, on July 20-24, 1980. The conference presents findings of 105 scientists from 20 countries on the chemistry and technology underlying the quality of foods and beverages. This volume is composed of 26 papers presented in the conference. It covers topics on ingredients of smoke and smoke flavor preparations; enzymatic flavor development in foods; enhancement of fruit flavors in dessert; practical applications of new forms of dried fruits; and quality evaluation of macadamia nuts. It also explains moisture relations of food microorganisms; pollution of liquid food by PVC container; views on food developments in Sweden and Italy; and advances in Shoyu research. Additionally, the advances in legume processing; changes in the organoleptic quality of spices and their oleoresinsin stored food products; and flavoring of extrusion cooked and textured meat extenders and analog are explained. This reference also discusses the determination of cocoa butter substitutes in chocolate; application of HPLC for evaluation of coffee flavor quality; and certain elements in Greek wines. This book is useful to all food industry practitioners, as it provides a comprehensive research reports on numerous chemical and technological facets of the quality of foods and beverages.

Book Description
In the course of the project COST 91 *, on the Effects of Thermal Processing and Distribution on the Quality and Nutritive Value of Food, it became clear that approved methods were needed for vitamin determination in food. An expert group on vitamins met in March 1981 to set the requirements which these methods must meet. On the basis of these requirements, methods were selected for vitamin A, ~-carotene, vitamin B1 (thiamine), vitamin C and vitamin E. Unfortunately, for vitamins B2 (riboflavin), B6 and D only tentative methods could be chosen, since the methods available only partially fulfilled the require ments set by the expert group. For niacin and folic acid some references only could be given because none of the existing methods satisfied these requirements, and for vitamin B , vitamin K, pantothenic acid and 12 biotin it was not considered possible to give even references. All methods were carefully described in detail so that every laboratory worker could use them without being an expert in vitamin assay. In October 1983 an enlarged expert group on vitamins approved the compilation of methods and approached a publishing house with a view to publication. The editors wish to thank Dr Peter Zeuthen, the leader of the project COST 91, for his interest in their work, and Mr G.

Book Description
Instrumental Analysis of Food: Recent Progress, Volume 2 provides an instrumental analysis of beverages. This book discusses the analysis of carbonates and bicarbonates in bottled water by autotitralizer; application of direct mass spectrometry for rapid analysis of organics in water beverages; and water sorption of coffee solubles by inverse gas chromatography. The flavor characteristics of the components of orange blossom Citrus aurantium; microstructure of protein gels in relation to their rheological properties; and glass capillary gas chromatography in the wine and spirit industry are also deliberated. This text likewise covers the analysis of the flavors in aged sake; determination of volatile phenols in rum and brandy by GC and LC; and capillary-chromatographic investigations on various grape varieties. This publication is beneficial to food technologists and specialists interested in analyzing of beverages.

Book Description
Seafood and seafood products represent some of the most important foods in almost all types of societies around the world. More intensive production of fish and shellfish to meet high demand has raised some concerns related to the nutritional and sensory qualities of these cultured fish in comparison to their wild-catch counterparts. In addition, t
