Lactose is a unique disaccharide found exclusively in the milk of mammals. This sugar has a crucial role in nourishing newborn and young mammals; however, some adults have difficulties in fully metabolizing lactose. Despite lactose intolerance in the population, the dairy industry produces 400,000 tons of crystalline lactose worldwide. The food and pharmaceutical industries use lactose as well as lactose derivatives in a wide variety of products. This book reviews some aspects of lactose properties and synthesis as well as recent advances in the recovery of lactose and lactose derivatives from cheese whey.
It would be difficult to imagine a more appropriate means of marking the Jubilee of the Dairy Research Laboratory, Division of Food Processing, CSIRO, than a publication on whey and lactose processing. The genesis of the Laboratory in 1939 was when the Australian dairy industry was very largely based on the supply of cream from farms to numerous butter factories, the skim milk being fed to pigs. By the mid-1940s, when Geof frey Loftus-Hills was appointed in charge ofthe fledgling Dairy Research Section, the main objective of the Section-the full utilization of the con stituents of milk for human food-had been firmly established. Over the next two decades progress towards this objective was exemplified by the scientific and technological contributions made in specialized milk powders for use in recombining and in the manufacture of casein and cheese. Meanwhile farming practices changed from cream production to the supply of refrigerated whole milk to the factories. By the late 1960s the increasing production of cheese and casein had re sulted in almost 2 million tonnes of whey per annum. This represented not only a waste disposal problem, but also under-utilization of over 100000 t of milk solids. The Laboratory had now grown to a staff of around 70, so it was possible to allocate some resources to this extra challenge.
This is the third volume in the series on the chemistry and physical chemistry of milk constituents. Volumes 1 and 2 dealt with the commercially important constituents proteins and lipids, respectively. Although the constituents dealt with in this volume are of less commercial importance, they are, nevertheless, of major significance in the chemical, physical, technological, nutritional and physiological properties of milk and milk products. The constituents of milk dealt with in this volume are lactose, water, milk salts and vitamins. The chemical and enzymatic modification of lactose and the physico-chemical properties of milk are also discussed.
A comprehensive overview on the advances in the field, this volume presents the science underpinning the probiotic and prebiotic effects, the latest in vivo studies, the technological issues in the development and manufacture of these types of products, and the regulatory issues involved. It will be a useful reference for both scientists and technologists working in academic and governmental institutes, and the industry.
Ranging from biofuels to building materials, and from cosmetics to pharmaceuticals, the list of products that may be manufactured using discards from farming and fishery operations is extensive. Byproducts from Agriculture and Fisheries examines the procedures and technologies involved in this process of reconstitution, taking an environmentally aware approach as it explores the developing role of value-added byproducts in the spheres of food security, waste management, and climate control. An international group of authors contributes engaging and insightful chapters on a wide selection of animal and plant byproducts, discussing the practical business of byproduct recovery within the vital contexts of shifting socio-economic concerns and the emergence of green chemistry. This important text: Covers recent developments, current research, and emerging technologies in the fields of byproduct recovery and utilization Explores potential opportunities for future research and the prospective socioeconomic benefits of green waste management Includes detailed descriptions of procedures for the transformation of the wastes into of value-added food and non-food products With its combination of practical instruction and broader commentary, Byproducts from Agriculture and Fisheries offers essential insight and expertise to all students and professionals working in agriculture, environmental science, food science, and any other field concerned with sustainable resources.
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 1990s. The series is the leading reference source on dairy chemistry, providing in-depth coverage of milk proteins, lipids, lactose, water and minor constituents. Advanced Dairy Chemistry Volume 3: Lactose, Water, Salts, and Minor Constituents, Third Edition, reviews the extensive literature on lactose and its significance in milk products. This volume also reviews the literature on milk salts, vitamins, milk flavors and off-flavors and the behaviour of water in dairy products. Most topics covered in the second 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. P.L.H. McSweeney Ph.D. is Associate Professor of Food Chemistry and P.F. Fox Ph.D., D.Sc. is Professor Emeritus of Food Chemistry at University College, Cork, Ireland.
R. S. SHALLENBERGER Cornell University, New York State Agricultural Research Station, New York, USA Among the material to be discussed in this first section of the 'Enzymes and Food Processing Symposium' is subject matter that can be viewed as a marriage between enzyme technology and sugar stereochemistry. In order to bring the significance of the material to be presented into proper perspective, I would like you to pretend, for a moment, that you are a researcher making a proposal on this subject to a Research Granting Agency in order to obtain financial support for your ideas. However, the year is 1880. Under the 'objectives' section of your proposal, you state that you intend to attach the intangible vital force or spirit-that is, the catalyst unique to the chemistry of living organisms-to an inert substrate such as sand. Thereafter you will pass a solution of right handed glucose (also known as starch sugar) past the 'vital force' and in the process convert it to left-handed glucose (also known as fruit sugar). The peer review committee would probably reject the proposal as sheer nonsense because the statements made were not only contrary to their experience, but also contrary to what they had been taught. Perhaps a few select people would have some feeling for what you were talking about, but commiseration would be the only form of support that they could offer.
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.
