Food Colorants

The colour of a food is central to consumer perceptions of quality. This important collection reviews key issues in controlling colour quality in food, from the chemistry of colour in food to measurement issues, improving natural colour and the use of colourings to improve colour quality.

In this second edition of Natural Food Colorants two new chapters have been added and we have taken the opportunity to revise all the other chapters. Each of the original authors have brought up to date their individual contributions, involving in several cases an expansion to the text by the addition of new material. The new chapters are on the role of biotechnology in food colorant production and on safety in natural colorants, two areas which have undergone considerable change and development in the past five years. We have also persuaded the publishers to indulge in a display of colours by including illustrations of the majority of pigments of importance to the food industry. Finally we have rearranged the order of the chapters to reflect a more logical sequence. We hope this new edition will be greeted as enthusiastically as the first. It remains for us, as editors, to thank our contributors for undertaking the revisions with such thoroughness and to thank Blackie A&P for their support and considerable patience. G. A. F. R. J. D.

Drawing on the expertise of internationally known, interdisciplinary scientists and researchers, Food Colorants: Chemical and Functional Properties provides an integrative image of the scientific characteristics, functionality, and applications of color molecules as pigments in food science and technology, as well as their impact on health. The book emphasizes the structure-function relationships of pigment molecules to explain biosynthesis, modifications and degradation during storage and processing, and the effect of these changes on quality and safety. Understanding the rate and nature of degradation assists in selecting optimum processing parameters. Beginning with an overview of the physics and biochemistry of color, the book focuses on the mechanics of pigment stability and bioavailability, and antioxidant and pro-oxidant action. It reviews the influence of pigments on health and metabolism, incorporating results of in vivo and in vitro studies. It addresses the occurrence of pigment in food matrices and their stability during processing and storage. Conventional technologies as well as new, environmentally friendly methods are presented along with recent advances in biotechnology to produce colorants. There is also a chapter on novel approaches to the biosynthesis of colorants by microalgae, microorganisms, and genetic engineering. Contributions give significant attention to analytical methods and recent advances in detecting both natural and synthetic colorants, their quality, quantity, and degradation during processing and storage. The book rounds out its comprehensive coverage with a look at quality and safety risk assessments and international regulations, as well as lists of formerly and newly approved colorants and additives. Peer reviewed contributions and critical evaluations ensure a concise, systematic presentation of the relationships between the chemical nature and functional properties of various natural and synthetic pigments used to color food.

In this book the author utilizes his over fifty years of experience in food chemistry and technology in order to produce the most detailed and comprehensive guide on natural food flavors and colors. Unique coverage of natural flavors and natural colorants in the same volume Includes chemical structures of all principal constituents and CAS, FEMA and E numbers. Wherever available FCC (Food Chemicals Codex) Includes techniques and characteristics of extracts, such as solvent extraction, dispersion and solubitization, nutraceutical function and effect of heat

This work focuses on the preparation, structure, chemistry, functional properties, stability, handling and applications of naturally-derived colorants approved for use in food products in the USA, Europe and Asia. It presents studies that investigate whether natural colorants reduce risk of heart disease, specific types of cancer, and other conditions.

Natural and Artificial Flavoring Agents and Dyes, Volume 7 in the Handbook of Food Bioengineering series, examines the use of natural vs. artificial food dyes and flavors, highlighting some of the newest production and purification methods. This solid resource explores the most recent trends and benefits of using natural agents over artificial in the production of foods and beverages. Using the newest technologies and evidence-based research methods, the book demonstrates how natural flavoring agents and dyes can be produced by plants, microorganisms and animals to produce higher quality foods that are more economical and safe to the consumer. Explores the most common natural compounds and how to utilize them with cutting edge technologies Includes information on the purification and production processes under various conditions Presents the latest research to show benefits of using natural additives

Thoroughly updated to accommodate recent research and state-of-the-art technologies impacting the field, Volume 2: Residues and Other Food Component Analysis of this celebrated 3 volume reference compiles modern methods for the detection of residues in foods from pesticides, herbicides, antibacterials, food packaging, and other sources. Volume 2 evaluates methods for: establishing the presence of mycotoxins and phycotoxins identifying growth promoters and residual antibacterials tracking residues left by fungicides and herbicides discerning carbamate and urea pesticide residues confirming residual amounts of organochlorine and organophosphate pesticides detecting dioxin, polychlorobiphenyl (PCB), and dioxin-like PCB residues ascertaining n-nitroso compounds and polycyclic aromatic hydrocarbons tracing metal contaminants in foodstuffs

Food Analysis by HPLC, Second Edition presents an exhaustive compilation of analytical methods that belong in the toolbox of every practicing food chemist. Topics covered include biosensors, BMO’s, nanoscale analysis systems, food authenticity, radionuclides concentration, meat factors and meat quality, particle size analysis, and scanning colorimity. It also analyzes peptides, carbohydrates, vitamins, and food additives and contains chapters on alcohols, phenolic compounds, pigments, and residues of growth promoters. Attuned to contemporary food industry concerns, this bestselling classic also features topical coverage of the quantification of genetically modified organisms in food.
