Milk Proteins

Food proteins are of great interest, not only because of their nutritional importance and their functionality in foods, but also for their detrimental effects. Although proteins from milk, meats (including fish and poultry), eggs, cereals, legumes, and oilseeds have been the traditional sources of protein in the human diet, potentially any proteins from a biological source could serve as a food protein. The primary role of protein in the diet is to provide the building materials for the synthesis of muscle and other tissues, and they play a critical role in many biological processes. They are also responsible for food texture, color, and flavor. Today, food proteins are extracted, modified, and incorporated into processed foods to impart specific functional properties. They can also have adverse effects in the diet: proteins, such as walnuts, pecans, almonds, and cashews, soybean, wheat, milk, egg, crustacean, and fish proteins can be powerful allergens for some people. Applied Food Protein Chemistry is an applied reference which reviews the properties of food proteins and provides in-depth information on important plant and animal proteins consumed around the world. The book is grouped into three sections: (1) overview of food proteins, (2) plant proteins, and (3) animal proteins. Each chapter discusses world production, distribution, utilization, physicochemical properties, and the functional properties of each protein, as well as its food applications. The authors for each of the chapters are carefully selected experts in the field. This book will be a valuable reference tool for those who work on food proteins. It will also be an important text on applied food protein chemistry for upper-level students and graduate students of food science programs.

Whey Proteins: From Milk to Medicine addresses the basic properties of whey proteins including chemistry, analysis, heat sensitivity, interactions with other proteins and carbohydrates, modifications (hydrolysis, aggregation, conjugation), their industrial preparation, processing and applications, quality aspects including flavour and effects of storage, as well as their role in nutrition, sports and exercise, and health and wellness. Readers of Whey Proteins will gain a better understanding of the chemical nature of the various whey proteins in cow’s milk and the milk of other species. This includes their unique physical and functional properties; the industrial processes used to extract them from milk, to process them into various forms, and to modify them to enhance their functionality; and their nutritive value and application in the fields of sports and exercise science, infant nutrition and medicine. This book is an essential resource for food and nutrition researchers, dairy and food companies, pharmaceutical organizations, and graduate students. Presents up-to-date coverage of whey proteins from milk to medicine Contains a description of the production and properties of whey protein products Offers an overview of the effects of thermal and non-thermal processes on whey protein characteristics Describes the rationale for, and benefits of, using whey proteins in health and wellness preparations

Milk proteins have nutritional value and extraordinary biological properties. Research over the last decades has provided new insight into the structure and the function of milk bioactive peptides. Some of these peptides are delivered directly into milk, and some are encrypted in major proteins such as caseins and lactoglobulins. These peptides have antimicrobial functions modulating the gut microflora. Even when milk is undisputedly the first food for mammals, milk proteins sometimes can be a health threat, either because of allergic reaction or because of toxicity. In this regard, in vitro studies showed donkey's casein and major whey proteins to be more digestible than cows' for human consumption. In this book, readers will find updated research on the major milk proteins' structure, bioactive peptides, milk protein allergy, therapeutic strategies, and chemical markers that can be used to detect cow milk intolerance in infants. This book provides the most current scientific information on milk proteins, from structure to biological properties. It will be of great benefit for those interested in milk production, milk chemistry, and human health.

A detailed account based on milk proteins has been highlighted in this profound book. It provides comprehensive information on a wide range of topics related to milk proteins. The content provided within will prove to be valuable to those interested in dairy foods, milk chemistry, human health, neonatal growth, lactation and mammary gland biology, milk proteins production and other related topics. This book delivers an insight into a range of topics related to milk proteins, including bioactivities of milk proteins and the peptides generated from those proteins, new functions assigned to some milk proteins, impact of processing of milk on milk proteins, allergies associated with consumption of milk, genetic variation of milk proteins, application of genomic technologies for exploring expression of proteins during milk synthesis and production of milk and milk proteins as affected by environmental factors.

This book reviews the state of knowledge and progress of research on food proteins, and in particular, milk proteins. Its basis is the Symposium on Milk Proteins that was held at the Federal Dairy Research Centre in Kiel, FRG, in June, 1988. Scien tists from around the world attended and addressed pure, as well as applied fields of protein research and technology. This book is divided into five sections, each adapted from the symposium's invited lectures, short communications, and poster presentations. New criteria for the "bio logical value" of dietary proteins and their relationships are considered according to: - Milk Proteins and Nitrogen Equilibrium - Milk Proteins and Ligands - Milk Proteins: Structural and Genetic Aspects - Milk Proteins: Technological and Functional Aspects - Milk Proteins and Clinical Nutrition Generally, different dietary proteins are classified according to their "biological value," i.e., their capacity to cause different retention of nitrogen in the body. But we think there are other intriguing leads worth studying that may help to identify which dietary proteins are best recommended for specific dietary situations or clini cal conditions. In addition, we have taken into consideration new fields such as attempts to determine the three-dimensional structure of proteins using two-dimensional NMR spectroscopy, and the application of genetic engineering to the lactating cell. In other words, we are on the way to the transgenic cow with customized milk constituents and composition.

Milk Proteins: Chemistry and Molecular Biology, Volume II provides an extensive and detailed discussion on individual milk proteins. This volume focuses on caseins, which constitute the major group of milk proteins, and provides an understanding of the formation and structure of casein micelles. The topics discussed include the formation and structure of casein micelles; isolation, properties, and zone electrophoresis of whole casein; casein and its attack by rennin (chymosin); biochemistry of prorennin (prochymosin) and rennin (chymosin); minor milk proteins and enzymes; milk protein research and milk technology; and milk proteins in prospect. This book is a good reference for students majoring in protein chemistry, as well as protein chemists and biochemists conducting research on milk proteins.
