With diet, health, and food safety news making headlines on a regular basis, the ability to separate, identify, and analyze the nutrients, additives, and toxicological compounds found in food and food components is more important than ever. This requires proper training in the application of best methods, as well as efforts to improve existing methods to meet analytical needs. Advances in instrumentation and applied instrumental analysis methods have allowed scientists concerned with food and beverage quality, labeling, compliance, and safety to meet these ever-increasing analytical demands. This updated edition of Methods of Analysis of Food Components and Additives covers recent advances as well as established methods in a concise guide, presenting detailed explanations of techniques for analysis of food components and additives. Written by leading scientists, many of whom personally developed or refined the techniques, this reference focuses primarily on methods of food analysis and novel analysis instruments. It provides readers with a survey of modern analytical instruments and methods for the analysis of food components, additives, and contaminants. Each chapter summarizes key findings on novel analysis methods, including the identification, speciation, and determination of components in raw materials and food products. The text describes the component or additive that can be analyzed, explains how it works, and then offers examples of applications. This reference covers selection of techniques, statistical assessments, analysis of drinking water, and rapid microbiological techniques. It also describes the application of chemical, physical, microbiological, sensorial, and instrumental novel analysis to food components and additives, including proteins, peptides, lipids, vitamins, carotenoids, chlorophylls, and food allergens, as well as genetically modified components, pesticide residues, pollutants, chemical preservatives, and radioactive components in foods. The Second Edition contains three valuable new chapters on analytical quality assurance, the analysis of carbohydrates, and natural toxins in foods, along with updates in the remaining chapters, numerous examples, and many new figures.

This new guide and reference concisely presents in one volume key information on the most important chemical and functional properties of food constituents, and the relationship of these properties to nutritional and sensory qualities of food. It also provides important information on how these properties are affected by harvesting, processing and storage. Included are chapters on rheological properties, food safety and mutagenic/carcinogenic components. The information was prepared by a team of food scientists from around the world and is based on the current international literature as well as the authors' expertise. The text is organized for easy reference, supplemented with numerous data tables, and illustrated by more than 40 schematics. Everybody expects food to be palatable, nutritious, and wholesome. These attributes are affected by the composition of the food, as well as by the properties and interactions of the constituents. They can be controlled by the recipe of the formulation, the conditions of storage and processing, and the enzymatic or chemical modifications of the components, mainly lipids, proteins, saccharides, and vitamins. The effectiveness of control depends on the understanding of the chemical and functional properties of the food components. Thus, food chemistry is a must for food technologists and for other technical personnel involved in food handling.

The focus of food science and technology has shifted from previous goals of improving food safety and enhancing food taste toward providing healthy and functional foods. Today’s consumers desire foods that go beyond basic nutrition—foods capable of promoting better health, or even playing a disease-prevention role. To meet this need for innovation, academic research must be combined with the development and commercialization strategies of industry. Innovation in Healthy and Functional Foods brings together this knowledge, with contributions from experts in biological science, food science, engineering, marketing, regulation, law, finance, sustainability, and management. Focusing on functional foods that have components added—such as omega-3, probiotics, and protein—to provide health benefits, this book presents various aspects of the innovation process. These include consumer insights, trends in developed and developing markets, and technological advances in functional foods and ingredients. It also addresses the key drivers of food industry innovation—affordability, sustainability, and tightening government regulations. Chapters cover characteristics of various markets around the world; consumer perception; food processing, packaging, and ingredients; innovation in functional ingredients; and functional ingredient delivery. Given the importance and challenges of getting functional food products into the marketplace, this book also covers the business aspects of innovation in food science, including marketing, financial implications, and commercial feasibility. Additionally, contributors provide insights into future trends, such as food tourism, nanotechnology, sustainability, and globalization. Bringing together expertise from academia and industry, this text provides an overview of contemporary food science, with wisdom and know-how in both innovation and commercialization, placing functional foods in a broader context for readers.

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.
