The Carotenoids book series provides an introduction to the fundamental chemistry, detailed accounts of the basic methods used in carotenoid research, and critical discussions of the biochemistry, functions and applications of carotenoids. Part 1 discusses the fundamental properties on which the biological functions and effects of carotenoids depend. Part 2 describes important natural functions of carotenoids in all kinds of living organisms.

Carotenoids were first studied as natural pigments, then as precursors of vitamin A, and then as bioactive compounds against chronic diseases. These compounds have been and continue to be the subject of intense research worldwide, now with an expanded scope. Food Carotenoids: Chemistry, Biology and Technology gathers all the important information about these major compounds which impact both food quality and human health. It integrates in one volume various aspects of food carotenoids, such as: Structures and physicochemical properties Biosynthetic pathways and metabolism Analysis and composition of foods Stability and reactions during processing Commercial production as food colorants and precursors of aroma compounds Bioavailability and health benefits Having worked with carotenoids in various aspects for 44 years, Delia Rodriguez-Amaya is uniquely placed to pass on her wealth of knowledge in this field. This book will serve as solid background information for professionals in Food Science, Food Technology, Nutrition, Agriculture, Biology, Chemistry and Medical Sciences, whether in the academe, industry, governmental and non-governmental agencies.

Presents state-of-the-art information on flavor precursor chemistry. Explains how biocatalysts are used either as tools to make specific ingredients or as reaction promoters in natural biochemical systems that generate flavor mixtures. Discusses processed flavors whereby carbohydrates, amino acids, lipids, and vitamins are heated under conditions mimicking food processing to generate flavors by thermal reactions. Presents complex model systems relating to the generation of processed flavors and examines the challenging analytical problems they present. Includes contributions from leading flavor chemists from Australia, Europe and the United States.

Understanding Wine Chemistry Understand the reactions behind the world’s most alluring beverages The immense variety of wines on the market is the product of multiple chemical processes – whether acting on components arising in the vineyard, during fermentation, or throughout storage. Winemaking decisions alter the chemistry of finished wines, affecting the flavor, color, stability, and other aspects of the final product. Knowledge of these chemical and biochemical processes is integral to the art and science of winemaking. Understanding Wine Chemistry has served as the definitive introduction to the chemical components of wine, their properties, and their reaction mechanisms. It equips the knowledgeable reader to interpret and predict the outcomes of physicochemical reactions involved with winemaking processes. Now updated to reflect recent research findings, most notably in relation to wine redox chemistry, along with new Special Topics chapters on emerging areas, it continues to set the standard in the subject. Readers of the second edition of Understanding Wine Chemistry will also find: Case studies throughout showing chemistry at work in creating different wine styles and avoiding common adverse chemical and sensory outcomes Detailed treatment of novel subjects like non-alcoholic wines, non-glass alternatives to wine packaging, synthetic wines, and more An authorial team with decades of combined experience in wine chemistry research and education Understanding Wine Chemistry is ideal for college and university students, winemakers at any stage in their practice, professionals in related fields such as suppliers or sommeliers, and chemists with an interest in wine.

As the links between health and food additives come under increasing scrutiny, there is a growing demand for food containing natural rather than synthetic additives and ingredients. Natural food additives, ingredients and flavourings reviews the legislative issues relating to natural food additives and ingredients, the range of natural food additives and ingredients, and their applications in different product sectors.After an exploration of what the term 'natural' means in the context of food ingredients, part one focuses on natural food colourings, low-calorie sweeteners and flavour enhancers, followed by a consideration of natural antioxidants and antimicrobials as food ingredients. The book goes on to review clean label starches and proteins, the application of natural hydrocolloids as well as natural aroma chemicals and flavourings from biotechnology and green chemistry. Part two considers specific applications in different products. Natural ingredients in savoury food products, baked goods and alcoholic drinks are examined, as are natural plant extracts in soft drinks and milk-based food ingredients.With is distinguished editors and expert team of international contributors, Natural food additives, ingredients and flavourings is an invaluable reference tool for all those involved in the development and production of foods with fewer synthetic additives and ingredients. - Reviews the legislative issues relating to natural food additives and ingredients, the range of natural food additives and ingredients, and their applications in different product sectors - Explores what the term 'natural' means in the context of food ingredients, focusses on natural food colourings, low-calorie sweeteners and flavour enhancers, and considers natural antioxidants and antimicrobials as food ingredients - Examines natural ingredients in savoury food products, baked goods and alcoholic drinks, natural plant extracts in soft drinks and milk-based food ingredients
