Use Of Yeast Biomass In Food Production

Yeast biomass is an excellent source of proteins, nucleic acids, and vitamins. It has been produced and consumed in baked goods and other foods for thousands of years and offers significant advantages when compared to other potential new microbial protein sources. Use of Yeast Biomass in Food Production provides up-to-date information regarding the chemical composition and biochemistry of yeasts, discusses the biotechnological basis of yeast production and possibilities for influencing yeast biomass composition using new techniques in molecular biology. The book examines techniques for producing yeast protein concentrates (and isolates) while still retaining their functional properties and nutritive values, as well as the various uses for these materials and their derivatives in different branches of the food industry. Finally, the book explores possibilities for the production and industrial use of other yeast components, such as nucleic acids, nucleotides, cell wall polysaccharides, autolysates, and extracts. Food microbiologists and technologists, as well as biotechnologists, will discover that this book is an invaluable reference resource.

Yeast - Industrial Applications is a book that covers applications and utilities of yeasts in food, chemical, energy, and environmental industries collected in 12 chapters. The use of yeasts in the production of metabolites, enzymatic applications, fermented foods, microorganism controls, bioethanol production, and bioremediation of contaminated environments is covered showing results, methodologies, and processes and describing the specific role of yeasts in them. The traditional yeast Saccharomyces cerevisiae is complemented in many applications with the use of less known non-Saccharomyces yeasts that now are being used extensively in industry. This book compiles the experience and know-how of researchers and professors from international universities and research centers.

Biotechnology has immense potential for resolving environmental problems and augmenting food production. Particularly, it offers solutions for converting solid wastes into value-added items. In food processing industries that generate voluminous by-products and wastes, valorization can help offset growing environmental problems and facilitate the sustainable use of available natural resources. Valorization of Food Processing By-Products describes the potential of this relatively new concept in the field of industrial residues management. The debut book in CRC Press’s new Fermented Foods and Beverages Series, this volume explores the current state of the art in food processing by-products with respect to their generation, methods of disposal, and problems faced in terms of waste and regulation. It reviews the basic fundamental principles of waste recycling, including process engineering economics and the microbiology and biochemical and nutritional aspects of food processing. It discusses fermentation techniques available for valorization of food processing by-products, enzyme technologies, and analytical techniques and instrumentation. Individual chapters examine the by-products of plant-based and animal-based food industries. The book also delves into socioeconomic considerations and environmental concerns related to food processing by-products. It surveys research gaps and areas ripe for further inquiry as well as future trends in the field. An essential reference for researchers and practitioners in the food science and food technology industry, this volume is also poised to inspire those who wish to take on valorization of food by-products as a professional endeavor. A contribution toward sustainability, valorization makes maximum use of agricultural produce while employing low-energy and cost-effective processes.

As a group of microorganisms, yeasts have an enormous impact on food and bev- age production. Scientific and technological understanding of their roles in this p- duction began to emerge in the mid-1800s, starting with the pioneering studies of Pasteur in France and Hansen in Denmark on the microbiology of beer and wine fermentations. Since that time, researchers throughout the world have been engaged in a fascinating journey of discovery and development – learning about the great diversity of food and beverage commodities that are produced or impacted by yeast activity, about the diversity of yeast species associated with these activities, and about the diversity of biochemical, physiological and molecular mechanisms that underpin the many roles of yeasts in food and beverage production. Many excellent books have now been published on yeasts in food and beverage production, and it is reasonable to ask the question – why another book? There are two different approaches to describe and understand the role of yeasts in food and beverage production. One approach is to focus on the commodity and the technology of its processing (e. g. wine fermentation, fermentation of bakery products), and this is the direction that most books on food and beverage yeasts have taken, to date. A second approach is to focus on the yeasts, themselves, and their bi- ogy in the context of food and beverage habitats.

Beverage production is among the oldest, though quantitatively most significant, applications of biotechnology methods, based on the use of microorganisms and enzymes. Manufacturing processes employed in beverage production, origi nally typically empirical, have become a sector of growing economic importance in the food industry. Pasteur's work represented the starting point for technological evolution in this field, and over the last hundred years progress in scientifically based research has been intense. This scientific and technological evolution is the direct result of the encounter between various disciplines (chemistry, biology, engineering, etc.). Beverage production now exploits all the various features of first and second-generation biotechnology: screening and selective im provement of microorganisms; their mutations; their use in genetic engineering methods; fermentation control; control of enzymatic processes, including industrial plants; use of soluble enzymes and immobilized enzyme reactors; development of waste treatment proc esses and so on. Research developments involving the use of biotechnology for the purpose of improving yields, solving quality-related problems and stimulating innovation are of particular and growing interest as far as production is concerned. Indeed, quality is the final result of the regulation of microbiological and enzymatic processes, and innovation is a consequence of improved knowledge of useful fermentations and the availability of new ingredients. The Council of Europe's sponsorship of the work which led to the contributions to this volume is clear evidence of the growing need for adequate information about scientific and technological progress.

Starter cultures have great significance in the food industry due to their vital role in the manufacture, flavour, and texture development of fermented foods. Once mainly used in the dairy industry, nowadays starter cultures are applied across a variety of food products, including meat, sourdough, vegetables, wine and fish. New data on the potential health benefits of these organisms has led to additional interest in starter bacteria. Starter Cultures in Food Production details the most recent insights into starter cultures. Opening with a brief description of the current selection protocols and industrial production of starter cultures, the book then focuses on the innovative research aspects of starter cultures in food production. Case studies for the selection of new starter cultures for different food products (sourdough and cereal based foods, table olives and vegetables, dairy and meat products, fish and wine) are presented before chapters devoted to the role of lactic acid bacteria in alkaline fermentations and ethnic fermented foods. This book will provide food producers, researchers and students with a tentative answer to the emerging issues of how to use starter cultures and how microorganisms could play a significant role in the complex process of food innovation.
