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.
Food colour additives have been the focus of much research in the last few years, and there is increasing consumer demand for natural and safer synthetic colours. This book reviews the natural and synthetic colours available, their properties and applications, as well as regulatory, sensory and analytical issues. Part one covers the development and safety of food colour additives. Part two covers properties and methods of analysis, and part three focuses on specific food product applications and future trends. - Reviews the natural and synthetic colour additives available for foods and beverages, looking at their properties and applications as well as regulatory, sensory and analytical issues - Expert analysis of natural origin colours, synthetic origin colours, overview of regulations, safety analysis and consumer health - Comprehensive coverage of properties and development in food colours: chemical purity, colour stability, and consumer sensory perception
As society has become increasingly concerned with the protection and preservation of the environment, many industries have been pushed to comply with new policies and social demands for more environmentally-friendly and sustainable practices and products. However, the textile dyeing industry remains a significant source of complex environmental issues with legislative requirements that often vary in detail and severity concerning the exposure and hazards of potentially harmful chemicals and other associated materials. It is vital that the industry sector involved in the application of dyes continues to be sensitive to potential adverse effects on the environment in its widest sense and respond accordingly. Impact of Textile Dyes on Public Health and the Environment is an essential reference source that focuses on the environmental impact and social responsibility of the dyeing industry. While highlighting topics such as toxicology, bleaching, and greenhouse gases, this publication is ideally designed for chemists, industrialists, non-governmental organization members, environmentalists, fashion designers, clothes manufacturers, scientists, academicians, researchers, students, and practitioners seeking current research on dyeing’s potentially adverse effects on the environment and strategic, effective responses.
Controlling, measuring, and "designing" the color of food are critical concerns in the food industry, as the appeal of food is chiefly determined visually, with color the most salient visual aspect. In 2010 at the International Color Association Interim Meeting held in Mar del Plata, Argentina, a multidisciplinary panel of food experts gathered to discuss the importance of color in food from perspectives ranging from chemistry to psychology to engineering. Select individuals from this elite symposium were invited to expand upon their presentations for publication in Color in Food: Technological and Psychophysical Aspects. The thematic scope of this volume comprises issues related to color research and application in various stages of food production, processing, marketing, purchasing, and consumption. Some of the questions raised in this thought-provoking volume include: What is the color of a glass of wine? What colors work best for "light" or diet products? Is the color measured in food the color we actually see? How does blueberry color change during storage? How are consumers motivated to buy bottled water based on packaging? What are the psychological effects of tablecloths and tray color on diners? Examining the latest developments in color research and application in relation to food science and technology, the book’s multidisciplinary approach makes it a critical resource for food technologists, color researchers, manufacturers of color measurement devices, and chemists and physicists working in the food industry.
Much of man's behaviour is controlled by appearance, but the appearance of his food is of paramount importance to his health and well-being. In day-to-day survival and marketing situations, we can or not most foods are fit to eat from their optical tell whether properties. Although vision and colour perception are the means by which we appreciate our surroundings, visual acceptance depends on more than just colour. It depends on total appearance. In the recent past the food technologist has been under pressure to increase his/her understanding of first, the behaviour of raw materials under processing, and second, the behaviour and motivation of his/her customers in a growing, more discriminating, and worldwide market. The chapters which follow describe the philosophy of total ap pearance, the factors comprising it, and its application to the food industry. Included are: considerations of the evolutionary, historical, and cultural aspects of food appearance; the physics and food chemistry of colour and appearance; the principles of sensory ap pearance assessment and appearance profile analysis, as well as instrumental measurement; the interaction of product appearance, control, and acceptance in the varied environments of the laboratory, production line, supermarket, home and restaurant. A broad examination has been made in an attempt to get into perspective the importance of appearance to all sectors of the industry.
Medicinal Foods as Potential Therapies for Type-2 Diabetes and Associated Diseases: The Chemical and Pharmacological Basis of their Action focuses on active pharmacological principles that modulate diabetes, associated risk factors, complications and the mechanism of action of widely used anti-diabetic herbal plants—rather than just the nutritional composition of certain foods. The book provides up-to-date information on acclaimed antidiabetic super fruits, spices and other food ingredients. Sections cover diabetes and obesity at the global level, the physiological control of carbohydrate and lipid metabolism, the pathophysiology of type-2 diabetes, the chemistry and pharmacology of a variety of spices, and much more. This book will be invaluable for research scientists and students in the medical and pharmaceutical sciences, medicinal chemistry, herbal medicine, drug discovery/development, nutrition science, and for herbal practitioners and those from the nutraceutical and pharm industries. - Provides background knowledge on type-2 diabetes and its pathophysiology and therapeutic targets down to the molecular level - Explores, in detail, the chemistry or secondary metabolites of the indicated foods that potentially modify diabetes and/or associated diseases - Examines the pharmacological findings on medicinal foods, including available clinical trials
