Alcohol has become the social and cultural necessity in today's society, though its role as part of diet is controversial. The alcohol is formed as a by-product of biochemical conversion of yeast on the sugars or carbohydrates of fruits. A typical alcoholic fermentation involves conversion of sugars, the most common substrate of fermentation, to typically produced products like ethanol, lactic acid, carbon dioxide, and hydrogen gas (H2). However, more exotic compounds can be produced by fermentation, which brings out the variation in the taste of the final product. The history of alcohol fermentation is as old as human civilization. Despite of being one of the most ancient fermentation processes known to mankind, alcohol fermentation is also one of the most diverse processes, bringing out variation in properties, taste, aroma and body of the product depending upon the changes in the fermentation process. The quantitative and qualitative effects of substrate concentration, yeast concentration, and nutrient supplementation directly effects the ethanol content, fermentation time, and ethanol productivity. Besides dietary contribution, alcohol from cellulosic substrate is now widely used as renewable energy source. This book is an effort to compile various studies of the alcohol fermentation process and the different substrates leading to differences in the final product.
A comprehensive two- volume set that describes the science and technology involved in the production and analysis of alcoholic beverages. At the heart of all alcoholic beverages is the process of fermentation, particularly alcoholic fermentation, whereby sugars are converted to ethanol and many other minor products. The Handbook of Alcoholic Beverages tracks the major fermentation process, and the major chemical, physical and technical processes that accompany the production of the world’s most familiar alcoholic drinks. Indigenous beverages and small-scale production are alsocovered to asignificant extent. The overall approach is multidisciplinary, reflecting the true nature of the subject. Thus, aspects of biochemistry, biology (including microbiology), chemistry, health science, nutrition, physics and technology are all necessarily involved, but the emphasis is on chemistry in many areas of the book. Emphasis is also on more recent developments and innovations, but there is sufficient background for less experienced readers. The approach is unified, in that although different beverages are dealt with in different chapters, there is extensive cross-referencing and comparison between the subjects of each chapter. Divided into five parts, this comprehensive two-volume work presents: INTRODUCTION, BACKGROUND AND HISTORY: A simple introduction to the history and development of alcohol and some recent trends and developments, FERMENTED BEVERAGES: BEERS, CIDERS, WINES AND RELATED DRINKS: the latest innovations and aspects of the different fermentation processes used in beer, wine, cider, liquer wines, fruit wines, low-alcohol and related beverages. SPIRITS: cover distillation methods and stills used in the production of whisky, cereal- and cane-based spirits, brandy, fruit spirits and liquers ANALYTICAL METHODS: covering the monitoring of processes in the production of alcoholic beverages, as well as sample preparation, chromatographic, spectroscopic, electrochemical, physical, sensory and organoleptic methods of analysis. NUTRITION AND HEALTH ASPECTS RELATING TO ALCOHOLIC BEVERAGES: includes a discussion on nutritional aspects, both macro- and micro-nutrients, of alcoholic beverages, their ingestion, absorption and catabolism, the health consequences of alcohol, and details of the additives and residues within the various beverages and their raw materials.
Technology & Engineering by M. Victoria Moreno-Arribas
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.
Excerpt from Alcoholic Fermentation Stahl specifically states that a body in such a state of internal dis quietude can very readily communicate the disturbance to another, which is itself at rest but is capable of undergoing a similar change, so that a putrefying or fermenting liquid can set another liquid in putre faction or fermentation. Taking account of the gradual accumulation of fact and theory we find at the time Of Lavoisier, from which the modern aspect of the problem dates, that Stahl's theoretical views were generally accepted. Alcoholic fermentation was known to require the presence of sugar and was thought to lead to the production of carbon dioxide acetic acid, and alcohol.

Asia has a long history of preparation and consumption of various types of ethnic fermented foods and alcoholic beverages based on available raw substrates of plant or animal sources and also depending on agro-climatic conditions of the regions. Diversity of functional microorganisms in Asian ethnic fermented foods and alcoholic beverages consists of bacteria (Lactic acid bacteria and Bacillus species, micrococcii, etc.), amylolytic and alcohol-producing yeasts and filamentous moulds. Though there are hundreds of research articles, review papers, and limited books on fermented foods and beverages, the present book: Ethnic Fermented Foods and Alcoholic Beverages of Asia is the first of this kind on compilation of various ethnic fermented foods and alcoholic beverages of Asia. This book has fifteen chapters covering different types of ethnic fermented foods and alcoholic beverages of Asia. Some of the authors are well-known scientists and researchers with vast experiences in the field of fermented foods and beverages who include Prof. Tek Chand Bhalla, Dr. Namrata Thapa (India), Prof. Yearul Kabir and Dr. Mahmud Hossain (Bangladesh), Prof. Tika Karki (Nepal), Dr. Saeed Akhtar (Pakistan), Prof. Sagarika Ekanayake (Sri Lanka), Dr. Werasit Sanpamongkolchai (Thailand), Prof. Sh. Demberel (Mongolia), Dr. Yoshiaki Kitamura, Dr. Ken-Ichi Kusumoto, Dr. Yukio Magariyama, Dr. Tetsuya Oguma, Dr. Toshiro Nagai, Dr. Soichi Furukawa, Dr. Chise Suzuki, Dr. Masataka Satomi, Dr. Kazunori Takamine, Dr. Naonori Tamaki and Dr. Sota Yamamoto (Japan), Prof. Dong-Hwa Shin, Prof. Cherl-Ho Lee, Dr. Young-Myoung Kim, Dr. Wan-Soo Park Dr. Jae-Ho Kim (South Korea) Dr. Maryam Tajabadi Ebrahimi (Iran), Dr. Francisco B.
