Opis

Provides thorough coverage of natural colorants and other pigments. Emphasizes nutraceutical properties and uses. Relates chemical structure to biochemical and functional properties and applications. Addresses the extraction and processing stability of individual pigments. Covers the use of biotechnology for increasing production of colorants. As our understanding of the science and functions of color in food has increased, the preferred colorants, forms of use, and legislation regulating their uses have also changed. Natural Colorants for Food and Nutraceutical Uses reflects the current tendency to use natural pigments. It details their science, technology, and applications as well as their nutraceutical properties. Starting with the basics, the book creates an understanding of physical colors, discusses color measurement, and analyzes why natural pigments are preferred today. The authors present an overview of global colorants, including safety, toxicity and regulatory aspects. Information about inorganic and synthetic colorants is included. The book then focuses on applications of natural colorants, with special attention given to characteristics, extraction and processing stability, and the use of biotechnology and molecular biology to increase colorant production. Finally, the book examines the nutraceutical properties of natural colorants and compares them to other well-known nutraceutical components. From the basics to highly specialized concepts and applications, Natural Colorants for Food and Nutraceutical Uses presents essential, practical information about pigments in the food industry. With its coverage of state-of-the-art technologies and future trends in the application of color to food, this book provides the most comprehensive, up-to-date survey of the field. While minimally processed foods satisfy the increasing demand for foods with fewer preservatives, higher nutritive value, and fresh sensory attributes, they also carry a greater

Recenzje

"With its coverage of state-of-the-art technologies and future trends in the application of colour to food, this book provides a comprehensive, up-to-date survey of the field and will be of interest to food scientists, technologists, food biotechnologists, food and flavour chemists, and biochemists."
