Biochemistry Of Milk Products

Biochemistry of milk products documents advances in the field and focuses on the two most active areas of research areas, which are starter cultures and enzymes for use in cheese and other foods, and factors influencing the functional properties of milk. The book covers the current thinking and research on the roles of proteinases and peptidases in the milk clotting process and in texture and flavour development during maturation of product. It also covers the protein engineering of enzymes and molecular biological manipulation of microorganisms, including the use of protein engineering to clarify the molecular basis of functional behavior and to manipulate protein properties in a defined and planned way. Biochemistry of milk products provides important reading for research workers, lecturers, graduates and final year undergraduates with interest in the practical applications of molecular biology, enzymology, and protein chemistry, not just in improving the quality and performance of dairy foods and ingredients but also in a much wider context.

This book is the most comprehensive introductory text on the chemistry and biochemistry of milk. It provides a comprehensive description of the principal constituents of milk (water, lipids, proteins, lactose, salts, vitamins, indigenous enzymes) and of the chemical aspects of cheese and fermented milks and of various dairy processing operations. It also covers heat-induced changes in milk, the use of exogenous enzymes in dairy processing, principal physical properties of milk, bioactive compounds in milk and comparison of milk of different species. This book is designed to meet the needs of senior students and dairy scientists in general.

not only of undergraduate and equivalent students, but of the new graduate entering industry and facing new and potentially frightening situations. To this end, the book is structured to meet the requirements both ofthe student, with a basic knowledge ofchemistry, biochemistry and microbiology and of persons working in the dairy industry. The basic approach isto discuss the manufacturingprocess in thecontextof technology and its related chemistry and microbiology, followed by a more fundamental appraisal of the underlying science. The dairy industry is defined in a broad context and information is included on imitationproducts and analogues. Anumber ofinnovations have been adopted in the presentation ofthe book. Information boxes and • points are used to place the text in a wider scientific and commercial context, and exercises are included in most chapters to encourage the reader to apply the knowledge gained from the book to unfamiliar situations. It is also our firm beliefthat the control of food manufacturing processes should be considered as an integral partofthe technology and for this reason control points, based on the HACCPsystem, are includedwhere appropriate. A note on using the book EXERCISES Exercises are not intended to be treated like an examination question. Indeed in many cases there is no single correct, or incorrect, answer.

Milk has been an important food for man since the domestication of cattle and the adoption of a pastoralist agriculture. It is also the most versatile of the animal-derived food commodities and is a component of the diet in many physical forms. In addition to milk itself, a rural technology evolved which permitted the manufacture of cheese, fer mented milks, cream and butter. At a later date, successive advances in technology were exploited in the manufacture of ice cream, concen trated and dried milks and, at a later date, of ultra-heat-treated dairy products, new dairy desserts and new functional products. At the same time, however, dairy products have been increasingly perceived as unhealthy foods and a number of high quality dairy substitutes, or analogues, have been developed which have made significant inroads into the total dairy food market. Paradoxically, perhaps, the technology which, on the one hand, presents a threat to the dairy industry through making possible high quality substitutes offers, on the other hand, an opportunity to exploit new uses for milk and its components and to develop entirely new dairy products. Further, the development of products such as low fat dairy spreads has tended to blur the distinction between the dairy industry and its imitators and further broadened the range of knowledge required of dairy scientists and technologists.

The Advanced Dairy Chemistry series was first published in four volumes in the 1980s (under the title Developments in Dairy Chemistry) and revised in three volumes in the late 1990s and again in the 2000s and 2010s. For nearly four decades, the series has been the leading reference source on dairy chemistry and is now in its fourth edition. Advanced Dairy Chemistry Volume 3: Lactose, Water, Salts, and Minor Constituents, fourth edition, reviews the extensive literature on lactose and its significance in milk products. This volume also reviews the literature on milk salts, vitamins, and the behaviour of water in dairy products and the physical properties of milk. Most topics covered in the third edition are retained in the current edition, which has been updated and expanded considerably. New chapters cover chemically and enzymatically prepared derivatives of lactose and oligosaccharides indigenous to milk and some chapters from earlier editions are consolidated.

This book covers recent developments in types, classifications, and genetic traits of indigenous milk microorganisms and dairy starter cultures. It also discusses biochemical reactions taking place in different dairy products and microorganisms involved in such reactions. The text provides strategies for rapid detection of pathogenic and non-pathog

The chemistry and physico-chemical properties of milk proteins are perhaps the largest and most rapidly evolving major areas in dairy chemistry. Advanced Dairy Chemistry-1B: Proteins: Applied Aspects covers the applied, technologically-focused chemical aspects of dairy proteins, the most commercially valuable constituents of milk. This fourth edition contains most chapters in the third edition on applied aspects of dairy proteins. The original chapter on production and utilization of functional milk proteins has been split into two new chapters focusing on casein- and whey-based ingredients separately by new authors. The chapters on denaturation, aggregation and gelation of whey proteins (Chapter 6), heat stability of milk (Chapter 7) and protein stability in sterilised milk (Chapter 10) have been revised and expanded considerably by new authors and new chapters have been included on rehydration properties of dairy protein powders (Chapter 4) and sensory properties of dairy protein ingredients (Chapter 8). This authoritative work describes current knowledge on the applied and technologically-focused chemistry and physico-chemical aspects of milk proteins and will be very valuable to dairy scientists, chemists, technologists and others working in dairy research or in the dairy industry.
