Book Description
Although bioactive compounds in milk and dairy products have been extensively studied during the last few decades – especially in human and bovine milks and some dairy products – very few publications on this topic are available, especially in other dairy species’ milk and their processed dairy products. Also, little is available in the areas of bioactive and nutraceutical compounds in bovine and human milks, while books on other mammalian species are non-existent. Bioactive Components in Milk and Dairy Products extensively covers the bioactive components in milk and dairy products of many dairy species, including cows, goats, buffalo, sheep, horse, camel, and other minor species. Park has assembled a group of internationally reputed scientists in the forefront of functional milk and dairy products, food science and technology as contributors to this unique book. Coverage for each of the various dairy species includes: bioactive proteins and peptides; bioactive lipid components; oligosaccharides; growth factors; and other minor bioactive compounds, such as minerals, vitamins, hormones and nucleotides, etc. Bioactive components are discussed for manufactured dairy products, such as caseins, caseinates, and cheeses; yogurt products; koumiss and kefir; and whey products. Aimed at food scientists, food technologists, dairy manufacturers, nutritionists, nutraceutical and functional foods specialists, allergy specialists, biotechnologists, medical and health professionals, and upper level students and faculty in dairy and food sciences and nutrition, Bioactive Components in Milk and Dairy Products is an important resource for those who are seeking nutritional, health, and therapeutic values or product technology information on milk and dairy products from the dairy cow and speciesbeyond. Areas featured are: Unique coverage of bioactive compounds in milks of the dairy cow and minor species, including goat, sheep, buffalo, camel, and mare Identifies bioactive components and their analytical isolation methods in manufactured dairy products, such as caseins, caseinates, and cheeses; yogurt products; koumiss and kefir; and whey products Essential for professionals as well as biotechnology researchers specializing in functional foods, nutraceuticals, probiotics, and prebiotics Contributed chapters from a team of world-renowned expert scientists

Milk and Dairy Products as Functional Foods
Author: Ara Kanekanian
Publisher: John Wiley & Sons
ISBN: 1118635086
Category : Technology & Engineering
Languages : en
Pages : 472
Book Description
There continues to be strong interest within the food industry in developing new products which offer functional health benefits to the consumer. The premium prices that can be charged make these added-value products lucrative for manufacturers, and they are also commercially popular. Dairy foods are central to this sector: they are good delivery systems for functional foods (yoghurts, milk drinks, spreads) and are also rich in compounds which can be extracted and used as functional ingredients in other food types. Milk and Dairy Products as Functional Foods draws together a wealth of information regarding the functional health benefits of milk and dairy products. It examines the physiological role and the claimed health effects of dairy constituents such as proteins, bioactive peptides, conjugated linoleic acid (CLA), omega 3 fatty acids vitamin D and calcium. These constituents have been shown to be, for example, anticarcinogenic, anti-inflammatory, antihypertensive, hypocholesterolemic, immune-modulating and antimicrobial. This book examines the evidence for these claims, and investigates practical approaches for utilising these attributes. The book is aimed at dairy scientists and technologists in industry and academia, general food scientists and technologists, microbiologists and nutritionists together with all those involved in the formulation and production of functional food products.

Category : Technology & Engineering
Languages : en
Pages : 1063
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.

Category : Technology & Engineering
Languages : en
Pages : 730
Book Description
THE ONLY SINGLE-SOURCE GUIDE TO THE LATEST SCIENCE, NUTRITION, AND APPLICATIONS OF ALL THE NON-BOVINE MILKS CONSUMED AROUND THE WORLD Featuring contributions by an international team of dairy and nutrition experts, this second edition of the popular Handbook of Milk of Non-Bovine Mammals provides comprehensive coverage of milk and dairy products derived from all non-bovine dairy species. Milks derived from domesticated dairy species other than the cow are an essential dietary component for many countries around the world. Especially in developing and under-developed countries, milks from secondary dairy species are essential sources of nutrition for the humanity. Due to the unavailability of cow milk and the low consumption of meat, the milks of non-bovine species such as goat, buffalo, sheep, horse, camel, Zebu, Yak, mare and reindeer are critical daily food sources of protein, phosphate and calcium. Furthermore, because of hypoallergenic properties of certain species milk including goats, mare and camel are increasingly recommended as substitutes in diets for those who suffer from cow milk allergies. This book: Discusses key aspects of non-bovine milk production, including raw milk production in various regions worldwide Describes the compositional, nutritional, therapeutic, physio-chemical, and microbiological characteristics of all non-bovine milks Addresses processing technologies as well as various approaches to the distribution and consumption of manufactured milk products Expounds characteristics of non-bovine species milks relative to those of human milk, including nutritional, allergenic, immunological, health and cultural factors. Features six new chapters, including one focusing on the use of non-bovine species milk components in the manufacture of infant formula products Thoroughly updated and revised to reflect the many advances that have occurred in the dairy industry since the publication of the acclaimed first edition, Handbook of Milk of Non-Bovine Mammals, 2nd Edition is an essential reference for dairy scientists, nutritionists, food chemists, animal scientists, allergy specialists, health professionals, and allied professionals.

Bioactive Components of Human Milk
Author: David S. Newburg
Publisher: Springer Science & Business Media
ISBN: 9780306466533
Category : Medical
Languages : en
Pages : 628
Book Description
The major emphasis in this book is a compilation and definition of what is known about components of human milk, including glycoconjugates, that inhibit common pathogens of the infant. Also discussed are other bioactive constituents whose relevant biological roles are also beginning to be defined. Hormonal and cytokine activity, immunomodulating and autoinflammatory agents, xenobiotics, and conditionally essential nutrients in milk could have roles in the protection of the infant, but may also participate in digestive processes, maternal--infant communication, maturation of the gut, central nervous system, and other components of infant growth and development. Like the protective activities, these are discussed in terms of their presence in milk, structures, potential functions, and structure/function relationship. Components whose role is nutritional support during early development of the infant are also included.

Handbook of Mineral Elements in Food
Author: Miguel de la Guardia
Publisher: John Wiley & Sons
ISBN: 1118654331
Category : Technology & Engineering
Languages : en
Pages : 800
Book Description
Mineral elements are found in foods and drink of all different types, from drinking water through to mothers’ milk. The search for mineral elements has shown that many trace and ultratrace-level elements presented in food are required for a healthy life. By identifying and analysing these elements, it is possible to evaluate them for their specific health-giving properties, and conversely, to isolate their less desirable properties with a view to reducing or removing them altogether from some foods. The analysis of mineral elements requires a number of different techniques – some methods may be suitable for one food type yet completely unsuited to another. The Handbook of Mineral Elements in Food is the first book to bring together the analytical techniques, the regulatory and legislative framework, and the widest possible range of food types into one comprehensive handbook for food scientists and technologists. Much of the book is based on the authors’ own data, most of which is previously unpublished, making the Handbook of Mineral Elements in Food a vital and up-to-the-minute reference for food scientists in industry and academia alike. Analytical chemists, nutritionists and food policy makers will also find it an invaluable resource. Showcasing contributions from international researchers, and constituting a major resource for our future understanding of the topic, the Handbook of Mineral Elements in Food is an essential reference and should be found wherever food science and technology are researched and taught.
