Many alcoholic beverages produced using various methods are consumed throughout the world. Alcoholic beverages made by brewing cereals, such as beer and Japanese sake, are extremely popular. Brewing them requires a complicated process by which the cereal must be saccharified using enzymes such as amylase. For example, with beer brewing, malt enzymes are used for saccharification. By germination, malt is made from barley to produce enzymes. Finally, wort is made by processing at higher temperatures using malt. The actual techniques require high-level skills. In this book, the discussion encompasses leading-edge brewing technology with fermentation using a non-Saccharomyces starter, healthy uses of spent grain from brewing processes, and an electronic nose for quality control, but it also includes descriptions of local traditional alcoholic beverages of Korea and Cameroon.

It is believed that beer has been produced, in some form, for thousands of years - the ancient Egyptians being one civilization with a knowledge of the fermentation process. Beer production has seen many changes over the centuries, and Brewing, Second Edition brings the reader right up to date with the advances in the last decade. Covering the various stages of beer production, reference is also made to microbiology within the brewery and some pointers to research on the topic are given. Written by a recently retired brewer, this book will appeal to all beer-lovers, but particularly those within the industry who wish to understand the processes, and will be relevant to students of food or biological sciences.

Brewing is designed for those involved in the malting, brewing, and allied industries who have little or no formal training in brewing science. While some elementary knowledge of chemistry and biology is necessary, the book clearly presents the essentials of brewing science and its relationship to brewing technology. Brewing focuses on the principles and practices most central to an understanding of the brewing process, including preparation of malt, hops, and yeast; the fermentation process; microbiology and contaminants; and finishing, packaging, and flavor. The second edition gives more emphasis to engineering and technological aspects, with the three new chapters on water, engineering and analysis. Brewing, Second Edition, is both a basic text for traditional college, short, and extension courses in brewing science, and a basic reference for anyone in the brewing industry.

Brewing continues to be one of the most competitive and innovative sectors in the food and drink industry. This important book summarises the major recent technological changes in brewing and their impact on product range and quality.The first group of chapters review improvements in ingredients, including cereals, adjuncts, malt and hops, as well as ways of optimising the use of water. The following sequence of chapters discuss developments in particular technologies from fermentation and accelerated processing to filtration and stabilisation processes as well as packaging. A final series of chapters analyse improvements in safety and quality control, covering such topics as modern brewery sanitation, waste handling, quality assurance schemes, and control systems responsible for chemical, microbiological and sensory analysis.With its distinguished editor and international team of contributors, Brewing: new technologies is a standard reference for R&D and Quality Assurance managers in the brewing industry. - Summarises the major recent technological changes in brewing - Reviews improvements in ingredients including cereals, malts and hops - Discusses developments in fermentation, filtration and packaging technologies

Brewing is one of the oldest and most complex technologies in food and beverage processing. Its success depends on blending a sound understanding of the science involved with an equally clear grasp of the practicalities of production. Brewing: science and practice provides a comprehensive and authoritative guide to both of these aspects of the subject.After an initial overview of the brewing process, malts, adjuncts and enzymes are reviewed. A chapter is then devoted to water, effluents and wastes. There follows a group of chapters on the science and technology of mashing, including grist preparation. The next two chapters discuss hops, and are followed by chapters on wort boiling, clarification and aeration. Three chapters are devoted to the important topics of yeast biology, metabolism and growth. Fermentation, fermentation technologies and beer maturation are then reviewed, followed by a consideration of native African beers. After a discussion of brewhouses, the authors consider a number of safety and quality issues, including beer microbiology and the chemical and physical properties of beer, which contribute to qualities such as flavour. A final group of chapters cover packaging, storage, distribution and the retail handling of beer.Based on the authors' unrivalled experience in the field, Brewing: science and practice is a standard work for the industry. - A detailed account of all stages of the brewing process - Safety and quality issues are discussed, including the chemical and physical properties of beer and beer microbiology - A strong partnership of the science and the practicalities of production ensures this book is a primary reference

Offers detailed studies of beer and its production as well as its commercial and economic aspects. All beverages worldwide which are beer-like in character and alcoholic content are reviewed. The book delineates over 900 chemical compounds that have been identified in beers, pinpoints their sources, gives concentration ranges, and examines their influence on beer quality. This work is intended for brewing, cereal and food chemists and biochemists; composition, nutrition, biochemical, food and quality assurance and control engineers; nutritionists; food biologists and technologists; microbiologists; toxicologists; and upper level undergraduate and continuing-education students in these disciplines.

During the latter part of the last century and the early years of this century, the microbiology of beer and the brewing process played a central role in the development of modern microbiology. An important advance was Hansen's development of pure culture yeasts for brewery fermentations and the recognition of different species of brewing and wild yeasts. The discovery by Winge of the life cycles of yeasts and the possibilities of hybridization were among the first steps in yeast genetics with subsequent far-reaching consequences. Over the same period the contaminant bacteria of the fermentation industries were also studied, largely influenced by Shimwell's pioneering research and resulting in the improvement of beer quality. Towards the end of the century, the influence of brewing microbiology within the discipline as a whole is far less important, but it retains an essential role in quality assurance in the brewing industry. Brewing microbiology has gained from advances in other aspects of microbiology and has adopted many of the techniques of biotechnology. Of particular relevance are the developments in yeast genetics and strain improvement by recombinant DNA techniques which are rapidly altering the way brewers view the most important microbiological components of the process: yeast and fermentation.

Much has happened in the brewing industry since the last edition of this book was published in 1996. In particular, there has been substantial con solidation of larger brewing companies as major multinational concerns, and at the other end of the spectrum the microbrewing scene in various parts of the world has become established as a sustainable enterprise. For those involved in the scientific and technical aspects of fermented bever age production the changes have been no less daunting. The complete genome sequence of Saccharomyces cerevisiae has been determined and studies are underway in numerous laboratories throughout the world to unravel the expression of the genome (transcriptomics and proteomics) and understand exactly "how a yeast works. " This will undoubtedly con tribute to our understanding of yeast fermentation and flavor generation in a revolutionary way because it will enable the simultaneous monitor ing of all genes in the organism during the fermentation. In Chapters 2 and 3 of this volume Colin Slaughter and John Hammond bring the reader up-to-date in this rapidly moving area and cover the remarkable achievements of modern biochemistry and molecular biology. lain Campbell has also revised the systematics of culture and wild yeasts in Chapter 7. The other major technical change since the last edition of this book is the introduction of molecular characterization and detection of microor ganisms based largely, but not exclusively, on the polymerase chain reac tion (PCR) for amplification of specific DNA fragments.

Microbial Technology: Fermentation Technology, Second Edition is a collection of papers that deals with fermentations and modifications of plant or animal products for foods, beverages, and feeds. The papers also review microbial technology: general principles, culture selection, laboratory methods, instrumentation, computer control, product isolation, immobilized cell usage, economics, and microbial patents. Several papers explain the process of fermentation and food modification in cheese, soy sauce, vinegar, mushroom, inocula for blue-veined cheeses, and blue cheese flavor. One paper discusses the technology of isolation, production, and application of microbial cultures which are commercially available or imminent as inocula for the treatment of wastes, The paper describes these cultures in terms of product characteristics, types of cultures, and application guidelines for waste treatment. Another paper outlines the procedures used by investigators involved in microbial reaction engineering, as follows: (1) identification of main products and substrates: (2) stoichiometry of the process; (3) kinetics and process rate; and (4) reactor design. One paper cites examples of immobilized cell systems utilized to prepare fine chemicals, such as the research of Chibata et al. (1975) and Yamamoto et al (1976, 1977). The collection is suitable for food technologists, bio-chemists, cellular biologists, micro-biologists, and scientists involved in food production, medicine, agriculture, and environmental control.
