We live in a world saturated by chemicals—our food, our clothes, and even our bodies play host to hundreds of synthetic chemicals that did not exist before the nineteenth century. By the 1900s, a wave of bright coal tar dyes had begun to transform the Western world. Originally intended for textiles, the new dyes soon permeated daily life in unexpected ways, and by the time the risks and uncertainties surrounding the synthesized chemicals began to surface, they were being used in everything from clothes and home furnishings to cookware and food. In A Rainbow Palate, Carolyn Cobbold explores how the widespread use of new chemical substances influenced perceptions and understanding of food, science, and technology, as well as trust in science and scientists. Because the new dyes were among the earliest contested chemical additives in food, the battles over their use offer striking insights and parallels into today’s international struggles surrounding chemical, food, and trade regulation.

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

This book provides an up-to-date insight into the chemistry behind the colour of the dyes and pigments that make our world so colourful. The impressive breadth of coverage starts with a dip into the history of colour science. Colour Chemistry then goes on to look at the structure and synthesis of the various dyes and pigments, along with their applications in the traditional areas of textiles, coatings and plastics, and also the ever-expanding range of "high-tech" applications. Also discussed are some of the environmental issues associated with the manufacture and use of colour. The broad and balanced coverage presented in this book makes it ideal for students and graduates. In addition, many specialists in industry or academia will also benefit from the overview of the subject that is provided.

This teacher resource contains background information and hands-on activities that explore traditional dyes derived from plant and animal sources. Students investigate how acidic (anionic) dyes react with wool and eggshells. Teachers will appreciate the reproducible classroom materials, cross-curricular integration ideas, and clear references to the National Science Education Standards. Appropriate for grades 9¿12.

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.

A 3-volume reference set you'll use every day. • Suppose you are the regulatory affairs manager for a food company, and your boss calls about "beet red", a coloring agent touted by a salesman as "natural". Your boss needs to know if this claim is true. How do you find out? • Perhaps you are an attorney for a company manufacturing ethnic marinade mixes and a customer charges that the chemical cinnamaldehyde, which the mixes contain, is being tested for carcinogenicity by the National Toxicology Program. Is your company manufacturing food that is potentially toxic? With the Encyclopedia of Food and Color Additives, the answers are at your fingertips: You quickly look up "Beet Red" and find it is indeed natural, a product of edible beets. You are able to assure your boss that the claim is valid. After consulting the Encyclopedia, you calmly inform the customer that cinnamaldehyde is not only approved for use in food, but it is a primary constituent of cinnamon, a common household spice. The Encyclopedia provides you with a quick, understandable description of what each additive is and what it does, where it comes from, when its use might be limited, and how it is manufactured and used. What? FDA or PAFA name: Listed in bold is the name by which the FDA classifies the substance. List of Synonyms: From the Chemical Abstract, the IUPAC name, and the common or "folklore" name for natural products are listed. Standardized names are provided for each substances. The most commonly used names are in bold type. Current CAS Number: The current FDA number for the substance. Other CAS Numbers: Numbers used previously or that are used by TSCA or EINICS to identify the substance. Empirical Formula: Indicates the relative proportion of elements in a molecule. Specifications: Includes melting point, boiling point, optical rotation, specific gravity, and more. Where? Description: Where the substance is grown; how it is cultivated, gathered, and brought to market; how it gets into food; species and subspecies producing this commodity; differences in geographical origin and how it impacts the quality of the product. Natural Occurrence: Lists family, genus, and species. Explains variances between the same substance grown and cultivated in different geographies. Natural Sources: For synthetic or nature-identical substances the Encyclopedia provides a list of foods in which a substance is naturally found. When?
