Color is one of the most significant cues used by consumers to determine the quality of a food. While color is usually assumed to be a property of the food itself, it is actually the individual's response to the visual signals generated by light on the product. An authoritative reference can best explain the ways that food color and quality are assessed and how they can be improved to benefit consumers and the food industry. This book reviews how color is perceived and measured, discusses food color chemistry and stability, and presents ways that color can be better controlled in food. Part one introduces the concept of the total appearance of food and examines the principles of instrumental color measurement, models of color appearance, color measurement by color reflectance, and sorting by color. Part two covers color control in food, focusing on the chemistry of food colorants, color stability, genetic modification for color enhancement, and developments in natural colorings.

The classic authority on colour measurement now fully revised and updated with the latest CIE recommendations The measurement of colour is of major importance in many commercial applications, such as the textile, paint, and foodstuff industries; as well as having a significant role in the lighting, paper, printing, cosmetic, plastics, glass, chemical, photographic, television, transport, and communication industries. Building upon the success of earlier editions, the 4th edition of Measuring Colour has been updated throughout with new chapters on colour rendering by light sources; colorimetry with digital cameras; factors affecting the appearance of coloured objects, and details of new CIE colour appearance models. Key features: Presents colour measurement, not simply as a matter of instrumentation and engineering, but also involving the physiology and psychology of the human observer. Covers the principles of colour measurement rather than a guide to instruments. Provides the reader with the basic facts needed to measure colour. Describes and explains the interactions between how colour is affected by the type of lighting, by the nature of the objects illuminated, and by the properties of the colour vision of observers. Includes many worked examples, and a series of Appendices provides the numerical data needed in many colorimetric calculations. The addition of 4th edition co-author, Dr. Pointer, has facilitated the inclusion of extensive practical advice on measurement procedures and the latest CIE recommendations.
Principles of Textile Finishing presents the latest information on textile finishing for industry professionals and researchers who are new to the field. As these processes are versatile and varied in their applications, the book provides information on how decisions on finishes and techniques may be made subjectively or based on experience. In addition, the book presents the desired final properties of textile materials and how they differ widely from product to product, helping finishers who face significant challenges in delivering fabrics that meet the requirements of end-users be successful. Written by an author who is an expert in the field, and who has with many years of experience in industry and academia, this book provides an accessible introduction to the principles, types, and applications of textile finishes.

This second edition of a unique text/reference identifies the appearance attributes of objects and the methods available for measuring them, bringing together much material not previously organized for ready reference. The primary premise here is that ``object appearance'' involves not only color, but such attributes as gloss, luster, and translucency. The first part of the book, concerned with nature of appearance, draws from the fields of physiology and psychology and considers the eye-brain combination and the way it receives and interprets light signals. This is followed by a consideration of the optical properties of objects from the physical standpoint. The second part of the book deals with the numerical scales used to measure object appearance. The discussion here draws on psychophysics in describing the uses of physical techniques to give numbers having psychological significance. The third part of the book covers instruments for the measurement of the attributes of object appearance, their principles of design, and a survey of the major ones in use. The final chapter discusses specific applications of appearance measurement. Includes appendixes and a glossary.
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.
Colorimetry, the science of quantitvely describing color, is essential for color reproduction technology. This is because it creates standards by which to measure color, using mathematical techniques and software to ensure fidelity across media, allow accurate color mixing, and to develop color optimization. This book is a comprehensive and thorough introduction to colorimetry, taking the reader from basic concepts through to a variety of industrial applications. Set out in clear, easy-to-follow terminology, Ohta and Robertson explain fundamental principles such as color specification, the CIE (International Commission on Illumination) system, and color vision and appearance models. They also cover the following topics: the optimization of color reproduction; uniform color spaces and color difference formulae, including the CIEDE 2000 formula; applications of metamerism, chromatic adaptation, color appearance and color rendering; mathematical formulae for calculating color mixing, maximising luminous efficacy, and designing illuminants with specific properties. Colorimetry: Fundamentals and Applications is an ideal reference for practising color engineers, color scientists and imaging professionals working on color systems. It is also a practical guide for senior undergraduate and graduate students who want to acquire knowledge in the field.
