This text is designed to acquaint the reader with the commonly used procedures of juice and wine analysis as they are generally practiced in the industry, and as they are taught in the Department of Enology at California State University, Fresno. It is assumed that the reader has a basic preparation in the fields of chemistry and microbiology. In developing material for this text, the authors have emphasized analyses as they would be carried out in a production laboratory. Realizing that different laboratories have different analytical capabilities, personnel as well as equip ment, we have in many instances provided several different approaches to the same analysis. Throughout this book we have attempted to give special attention to practical considerations and the importance of these analyses in the total spectrum of winery operations. We hope the book's format will satisfy the inter ests oflaboratory personnel as well as winemakers. The process of making wine involves a series of concerns for the winemaker and staff of a winery. The first concerns are viticultural. Upon arrival of the fruit, its quality is assessed, grapes are processed and fermentation is begun. Almost immediately, and in many instances simultaneously, chemical and microbiological stability of the young and/or aging wine become important. Finally, problems do occur on occasion, and a number of what may be consid ered remedial techniques can be employed to produce an acceptable product.

In recent years, new yeast species have proven their value and novel biotechnological applications have emerged. This book compiles the multi-faceted genetic repertoire of several yeasts relevant to modern biotechnology, and describes their utilization in research and application in the light of their genetic make-up and physiological characteristics. Moreover, the book presents a thorough overview of a wide array of methodologies from classical genetics to modern genomics technologies that have been and are being used in functional analysis of yeasts.

Yeasts are the active agents responsible for three of our most important foods - bread, wine, and beer - and for the almost universally used mind/ personality-altering drug, ethanol. Anthropologists have suggested that it was the production of ethanol that motivated primitive people to settle down and become farmers. The Earth is thought to be about 4. 5 billion years old. Fossil microorganisms have been found in Earth rock 3. 3 to 3. 5 billion years old. Microbes have been on Earth for that length of time carrying out their principal task of recycling organic matter as they still do today. Yeasts have most likely been on Earth for at least 2 billion years before humans arrived, and they playa key role in the conversion of sugars to alcohol and carbon dioxide. Early humans had no concept of either microorganisms or fermentation, yet the earliest historical records indicate that by 6000 B. C. they knew how to make bread, beer, and wine. Earliest humans were foragers who col lected and ate leaves, tubers, fruits, berries, nuts, and cereal seeds most of the day much as apes do today in the wild. Crushed fruits readily undergo natural fermentation by indigenous yeasts, and moist seeds germinate and develop amylases that produce fermentable sugars. Honey, the first con centrated sweet known to humans, also spontaneously ferments to alcohol if it is by chance diluted with rainwater. Thus, yeasts and other microbes have had a long history of 2 to 3.

Fermentation, as a chemical and biological process, is everywhere. Countless societies throughout history have used it to form a vast array of foods and drinks, many of which were integral and essential to those cultures; it could be argued that the production of beer and bread formed the basis of many agriculture-based civilizations. Today, nearly every person on the planet consumes fermented products, from beer and wine, to bread and dairy products, to certain types of meat and fish. Fermentation is a nearly ubiquitous process in today's food science, and an aspect of chemistry truly worth understanding more fully. In The Oxford Handbook of Food Fermentations, Charles W. Bamforth and Robert E. Ward have collected and edited contributions from many of the world's experts on food fermentation, each focused on a different fermentation product. The volume contains authoritative accounts on fermented beverages, distilled beverages, and a diverse set of foods, as well as chapters on relevant biotechnology. Each chapter embraces the nature of the product, its production, and its final composition. The text also touches on the raw materials and processes involved in producing packaged foodstuff, and the likely future trends in each area. In the conclusion, Bamforth and Ward present a comparison between the various products and the diverse technologies employed to produce them. Fermentation is a multifaceted process that affects a wide variety of products we consume, and The Oxford Handbook of Food Fermentations is the definitive resource that captures the science behind fermentation, as well as its diverse applications.

Fungi: Biology and Applications, Second Edition provides a comprehensive treatment of fungi, covering biochemistry, genetics and the medical and economic significance of these organisms at introductory level. With no prior knowledge of the subject assumed, the opening chapters offer a broad overview of the basics of fungal biology, in particular the physiology and genetics of fungi and also a new chapter on the application of genomics to fungi. Later chapters move on to include more detailed coverage of topics such as antibiotic and chemical commodities from fungi, new chapters on biotechnological use of fungal enzymes and fungal proteomics, and fungal diseases of humans, antifungal agents for use in human therapy and fungal pathogens of plants.

The use of non-Saccharomyces yeast species is currently a biotechnology trend in enology for which they are being broadly used to improve the sensory profile of wines because they affect aroma, color, and mouthfeel. They have become a powerful biotool to modulate the influence of global warming on grape varieties, helping to maintain the acidity, decrease the alcoholic degree, stabilize wine color, and increase freshness. In cool climates, some non-Saccharomyces can promote demalication or color stability by the formation of stable derived pigments. Additionally, non-Saccharomyces yeasts open new possibilities in biocontrol for removing spoilage yeast and bacteria or molds that can produce and release mycotoxins and, thereby, help in reducing applied SO2 levels.

Bread and leavened bakery products have been essential to human nourishment for millennia. Traditionally, bread production has relied on the use of sourdough as a leavening agent and to impart a characteristic quality to baked goods. In recent years, improved understanding of the biodiversity and microbial ecology of sourdough microbiota, the discovery of new species, the improved management and monitoring of its meta-community and the commercialization of innovative products have vastly expanded the potential of sourdough fermentation for making baked goods. For example, raw materials such as cereals, pseudo-cereals, ancient grains, and gluten-free substrates, as well as a large number of baked good varieties (e.g., typical and industrial breads, sweet baked goods, gluten-free products) may benefit from advances in sourdough fermentation. In addition, biotechnological tools and culture properties have been discovered to improve both the shelf life and the sensory and textural qualities of baked goods, as well as their nutritional and health-promoting properties. Now in its second edition, the Handbook on Sourdough Biotechnology remains the only book dedicated completely to sourdough biotechnology with the contribution of the most experienced researchers from the field. It reviews the history of sourdough and the potential of sourdough fermentation in the production of bread and baked goods. A thorough discussion of the various processing steps includes the chemical properties of the raw matter, the taxonomy, diversity, and metabolic properties of starter yeasts and lactic acid bacteria, and the effects of sourdough fermentation on the shelf life and the sensory, textural, nutritional, and health-promoting properties of baked goods.
