In the beginning, for me, winemaking was a romanticized notion of putting grape juice into a barrel and allowing time to perform its magic as you sat on the veranda watching the sunset on a Tuscan landscape. For some small wineries, this notion might still ring true, but for the majority of wineries commercially producing quality wines, the reality of winemaking is far more complex. The persistent evolution of the wine industry demands continual advan- ments in technology and education to sustain and promote quality winem- ing. The sciences of viticulture, enology, and wine chemistry are becoming more intricate and sophisticated each year. Wine laboratories have become an integral part of the winemaking process, necessitating a knowledgeable staff possessing a multitude of skills. Science incorporates the tools that new-age winemakers are utilizing to produce some of the best wines ever made in this multibillion dollar trade. A novice to enology and wine chemistry can find these subjects daunting and intimidating. Whether you are a home winemaker, a new winemaker, an enology student, or a beginning-to-intermediate laboratory technician, p- ting all the pieces together can take time. As a winemaker friend once told me, “winemaking is a moving target. ” Introduction to Wine Laboratory Practices and Procedures was written for the multitude of people entering the wine industry and those that wish to learn about wine chemistry and enology.

Science and Technology of Fruit Wine Production includes introductory chapters on the production of wine from fruits other than grapes, including their composition, chemistry, role, quality of raw material, medicinal values, quality factors, bioreactor technology, production, optimization, standardization, preservation, and evaluation of different wines, specialty wines, and brandies. Wine and its related products have been consumed since ancient times, not only for stimulatory and healthful properties, but also as an important adjunct to the human diet by increasing satisfaction and contributing to the relaxation necessary for proper digestion and absorption of food. Most wines are produced from grapes throughout the world, however, fruits other than grapes, including apple, plum, peach, pear, berries, cherries, currants, apricot, and many others can also be profitably utilized in the production of wines. The major problems in wine production, however, arise from the difficulty in extracting the sugar from the pulp of some of the fruits, or finding that the juices obtained lack in the requisite sugar contents, have higher acidity, more anthocyanins, or have poor fermentability. The book demonstrates that the application of enzymes in juice extraction, bioreactor technology, and biological de-acidification (MLF bacteria, or de-acidifying yeast like schizosaccharomyces pombe, and others) in wine production from non-grape fruits needs serious consideration. Focuses on producing non-grape wines, highlighting their flavor, taste, and other quality attributes, including their antioxidant properties Provides a single-volume resource that consolidates the research findings and developed technology employed to make wines from non-grape fruits Explores options for reducing post-harvest losses, which are especially high in developing countries Stimulates research and development efforts in non-grape wines

The ancient beverage wine is the result of the fermentation of grape must. This n- urally and fairly stable product has been and is being used by many human societies as a common or enjoyable beverage, as an important means to improve the quality of drinking water in historical times, as therapeutical agent, and as a religious symbol. During the last centuries, wine has become an object of scientific interest. In this respect different periods may be observed. At first, simple observations were recorded, and subsequently, the chemical basis and the involvement of microorg- isms were elucidated. At a later stage, the scientific work led to the analysis of the many minor and trace compounds in wine, the detection and understanding of the biochemical reactions and processes, the diversity of microorganisms involved, and the range of their various activities. In recent years, the focus shifted to the genetic basis of the microorganisms and the molecular aspects of the cells, including metabolism, membrane transport, and regulation. These different stages of wine research were determined by the scientific methods that were known and available at the respective time. The recent “molecular” approach is based on the analysis of the genetic code and has led to significant results that were not even imaginable a few decades ago. This new wealth of information is being presented in the Biology of Microorganisms on Grapes, in Must, and in Wine.

Enological Chemistry is written for the professional enologist tasked with finding the right balance of compounds to create or improve wine products. Related titles lack the appropriate focus for this audience, according to reviewers, failing either to be as comprehensive on the topic of chemistry, to include chemistry as part of the broader science of wine, or targeting a less scientific audience and including social and historical information not directly pertinent to the understanding of the role of chemistry in successful wine production. The topics in the book have been sequenced identically with the steps of the winemaking process. Thus, the book describes the most salient compounds involved in each vinification process, their properties and their balance; also, theoretical knowledge is matched with its practical application. The primary aim is to enable the reader to identify the specific compounds behind enological properties and processes, their chemical balance and their influence on the analytical and sensory quality of wine, as well as the physical, chemical and microbiological factors that affect their evolution during the winemaking process. Organized according to the winemaking process, guiding reader clearly to application of knowledge Describes the most salient compounds involved in each step enabling readers to identify the specific compounds behind properties and processes and effectively work with them Provides both theoretical knowledge and practical application providing a strong starting point for further research and development

The aim of this book is to describe chemical and biochemical aspects of winemaking that are currently being researched. The authors have selected the very best experts for each of the areas. The first part of the book summarizes the most important aspects of winemaking technology and microbiology. The second most extensive part deals with the different groups of compounds, how these are modified during the various steps of the production process, and how they affect the wine quality, sensorial aspects, and physiological activity, etc. The third section describes undesirable alterations of wines, including those affecting quality and food safety. Finally, the treatment of data will be considered, an aspect which has not yet been tackled in any other book on enology. In this chapter, the authors not only explain the tools available for analytical data processing, but also indicate the most appropriate treatment to apply, depending on the information required, illustrating with examples throughout the chapter from enological literature.

Food proteins and bioactive peptides play a vital role in the growth and development of the body’s structural integrity and regulation, as well as having a variety of other functional properties. Land animal-derived food proteins such as collagen and gelatine carry risks of contamination (such as BSE). Marine-derived proteins, which can provide equivalents to collagen and gelatin without the associated risks, are becoming more popular among consumers because of their numerous health beneficial effects. Most marine-derived bioactive peptides are currently underutilized. While fish and shellfish are perhaps the most obvious sources of such proteins and peptides, there is also the potential for further development of proteins and peptides from sources like algae, sea cucumber and molluscs. Marine-derived proteins and peptides also have potential uses in novel products, with the possibility of wide commercialization in the food, beverage, pharmaceutical and cosmetic industries, as well as in other fields such as photography, textiles, leather, electronics, medicine and biotechnology. Marine Proteins and Peptides: Biological Activities and Applications presents an overview of the current status, future industrial perspectives and commercial trends of bioactive marine-derived proteins and peptides. Many of the industrial perspectives are drawn from the food industry, but the book also refers to the pharmaceutical and cosmetics industries. There have recently been significant advances in isolating functional ingredients from marine bio-resources and seafood by-products for use in these industries, but little has been published, creating a knowledge gap, particularly with regard to the isolation and purification processes. This book is the first to fill that gap. Marine Proteins and Peptides: Biological Activities and Applications is a valuable resource for researchers in marine biochemistry field as well as food industry managers interested in exploring novel techniques and knowledge on alternative food protein sources. It will become a standard reference book for researchers involved in developing marine bio-resources and seafood by-products for novel nutraceutical, cosmetics, and pharmaceutical applications. It will also appeal to managers and product developers in the food, pharmaceutical and cosmetics industries, particularly those looking to use marine-derived proteins and peptides as substitutes or replacements for unfashionable or outdated food components.

Winemaking as a form of food preseIVation is as old as civilization. Wine has been an integral component of people's daily diet since its discovery and has also played an important role in the development of society, reli gion, and culture. We are currently drinking the best wines ever produced. We are able to do this because of our increased understanding of grape growing, biochemistry and microbiology of fermentation, our use of ad vanced technology in production, and our ability to measure the various major and minor components that comprise this fascinating beverage. Historically, winemakers succeeded with slow but gradual improvements brought about by combinations of folklore, obseIVation, and luck. How ever, they also had monumental failures resulting in the necessity to dis pose of wine or convert it into distilled spirits or vinegar. It was assumed that even the most marginally drinkable wines could be marketed. This is not the case for modem producers. The costs of grapes, the technology used in production, oak barrels, corks, bottling equipment, etc. , have in creased dramatically and continue to rise. Consumers are now accustomed to supplies of inexpensive and high-quality varietals and blends; they con tinue to demand better. Modem winemakers now rely on basic science and xvi Preface xvii the systematic application of their art to produce products pleasing to the increasingly knowledgeable consumer base that enjoys wine as part of its civilized society.
