Book Description
This Brief reviews the chemistry behind the production of yoghurt through acidification of milk. It quantifies the changes in physical and chemical properties of yoghurt during fermentation with microbial organisms (such as Lactobacillus bulgaricus and Streptococcus thermophilus). It has been found that this symbiosis has an optimal development at a temperature of ca. 45°C with the transformation of lactose into lactic acid and small amounts of acetaldehyde, diacetyl and volatile acids. This Brief explains the chemical and physical results of the fermentation process, such as precipitation of proteins and the acid coagulation of milk with a clot formation in the final semi-solid mass. The Brief sheds light on the accomplishments of the fermenting organisms: they are responsible for the biochemical reactions of carbohydrate metabolism, proteolysis, lipolysis and flavour production in the process of yoghurt production. It also briefly reviews formulations and food additives used in the modern yoghurt producing industry.

Book Description
Previous editions of Yoghurt: Science and Technology established the text as an essential reference underpinning the production of yoghurt of consistently high quality. The book has been completely revised and updated to produce this third edition, which combines coverage of recent developments in scientific understanding with information about established methods of best practice to achieve a comprehensive treatment of the subject. General acceptance of a more liberal definition by the dairy industry of the term yoghurt has also warranted coverage in the new edition of a larger variety of gelled or viscous fermented milk products, containing a wider range of cultures.Developments in the scientific aspects of yoghurt covered in this new edition include polysaccharide production by starter culture bacteria and its effects on gel structure, acid gel formation and advances in the analysis of yoghurt in terms of its chemistry, rheology and microbiology. Significant advances in technology are also outlined, for example automation and mechanisation. There has also been progress in understanding the nutritional profile of yoghurt and details of clinical trials involving yoghurts are described.This book is a unique and essential reference to students, researchers and manufacturers in the dairy industry. - Includes developments in the understanding of the biochemical changes involved in yoghurt production - Outlines significant technological advances in mechanisation and automation - Discusses the nutritional value of yoghurt

Book Description
This Brief explains and discusses honey and its production from a chemical perspective. It outlines why honey is a special and unique food, being produced by bees from the nectar of plants or from secretions of living parts of plants. Although glucose and fructose are the main constituents of honey, its overall composition is far from being simple or uniform: other substances such as organic acids, enzymes, or minerals are found in varying amounts. In this Brief, the author addresses the factors that influence the composition of the honey as well as the consequences that the composition has on properties such as color, crystallization, density, viscosity, or the refractive index. This Brief also introduces some of the most commonly used quality parameters for the determination of ageing and/or overheating: 5-hydroxymethylfurfural (HMF) and diastase. Other recently proposed constituents for quality parameters are also mentioned, e.g. 1,2 dicarbonyl compounds (3 deoxyglucosone, methylglyoxal, glyoxal) and furosine, also named 2-furoylmethyl lysine.

Book Description
Milk is nature’s most complete food, and dairy products are considered to be the most nutritious foods of all. The traditional view of the role of milk has been greatly expanded in recent years beyond the horizon of nutritional subsistence of infants: it is now recognized to be more than a source of nutrients for the healthy growth of children and nourishment of adult humans. Alongside its major proteins (casein and whey), milk contains biologically active compounds, which have important physiological and biochemical functions and significant impacts upon human metabolism, nutrition and health. Many of these compounds have been proven to have beneficial effects on human nutrition and health. This comprehensive reference is the first to address such a wide range of topics related to milk production and human health, including: mammary secretion, production, sanitation, quality standards and chemistry, as well as nutrition, milk allergies, lactose intolerance, and the bioactive and therapeutic compounds found in milk. In addition to cow’s milk, the book also covers the milk of non-bovine dairy species which is of economic importance around the world. The Editors have assembled a team of internationally renowned experts to contribute to this exhaustive volume which will be essential reading for dairy scientists, nutritionists, food scientists, allergy specialists and health professionals.

Book Description
While many food science programs offer courses in the microbiology and processing of fermented foods, no recently published texts exist that fully address the subject. Food fermentation professionals and researchers also have lacked a single book that covers the latest advances in biotechnology, bioprocessing, and microbial genetics, physiology, and taxonomy. In Microbiology and Technology of Fermented Foods, Robert Hutkins has written the first text on food fermentation microbiology in a generation. This authoritative volume also serves as a comprehensive and contemporary reference book. A brief history and evolution of microbiology and fermented foods, an overview of microorganisms involved in food fermentations, and their physiological and metabolic properties provide a foundation for the reader. How microorganisms are used to produce fermented foods and the development of a modern starter culture industry are also described. Successive chapters are devoted to the major fermented foods produced around the world with coverage including microbiological and technological features for manufacture of these foods: Cultured Dairy Products Cheese Meat Fermentation Fermented Vegetables Bread Fermentation Beer Fermentation Wine Fermentation Vinegar Fermentation Fermentation of Foods in the Orient Examples of industrial processes, key historical events, new discoveries in microbiology, anecdotal materials, case studies, and other key information are highlighted throughout the book. Comprehensively written in a style that encourages critical thinking, Microbiology and Technology of Fermented Foods will appeal to anyone dealing in food fermentation – students, professors, researchers, and industry professionals.

Book Description
This Brief defines reliable correlations between the food packaging design and its chemical features in terms of an 'integrated food product' (the synergistic union composed of the edible content and its container). A good design, as described in this Brief, implies the best choices from a series of possibilities, taking into account economical and commercial influences or limitations in the production and processing chain and the chemical interactions that can arise between the food containers and the contained edible material. This Brief highlights how the different requirements can be combined, while avoiding dangerous food risks originating from the chemical interaction between the container and the product. Different designs are critically analysed with relation to the effect on contained foods. The influences and resulting consequences of different possible food packaging designs are highlighted and discussed in selected case studies for some every-day products (like potato chips).
