Download or read book Sustainable Protein Sources written by Sudarshan Nadathur and published by Academic Press. This book was released on 2016-10-02 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein plays a critical role in human nutrition. Although animal-derived proteins constitute the majority of the protein we consume, plant-derived proteins can satisfy the same requirement with less environmental impact. Sustainable Protein Sources allows readers to understand how alternative proteins such as plant, fungal, algal, and insect protein can take the place of more costly and less efficient animal-based sources. Sustainable Protein Sources presents the various benefits of plant and alternative protein consumption, including those that benefit the environment, population, and consumer trends. The book presents chapter-by-chapter coverage of protein from various sources, including cereals and legumes, oilseeds, pseudocereals, fungi, algae, and insects. It assesses the nutrition, uses, functions, benefits, and challenges of each of these proteins. The book also explores opportunities to improve utilization and addresses everything from ways in which to increase consumer acceptability, to methods of improving the taste of products containing these proteins, to the ways in which policies can affect the use of plant-derived proteins. In addition, the book delves into food security and political issues which affect the type of crops that are cultivated and the sources of food proteins. The book concludes with required consumer choices such as dietary changes and future research ideas that necessitate vigorous debate for a sustainable planet. - Introduces the need to shift current animal-derived protein sources to those that are more plant-based - Presents a valuable compendium on plant and alternate protein sources covering land, water, and energy uses for each type of protein source - Discusses nutritive values of each protein source and compares each alternate protein to more complete proteins - Provides an overview of production, including processing, protein isolation, use cases, and functionality - Presents solutions to challenges, along with taste modulation - Focuses on non-animal derived proteins - Identifies paths and choices that require consumer and policymaker debate and action

Download or read book Multi Scale Modeling of Structural Concrete written by Koichi Maekawa and published by CRC Press. This book was released on 2008-11-28 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increases in computer power have now enabled engineers to combine materials science with structural mechanics in the design and the assessment of concrete structures. The techniques developed have become especially useful for the performance assessment of such structures under coupled mechanistic and environmental actions. This allows effective management of infrastructure over a much longer life cycle, thus satisfying the requirements for durability and sustainability. This ground-breaking new book draws on the fields of materials and structural mechanics in an integrated way to address the questions of management and maintenance. It proposes a realistic way of simulating both constituent materials and structural responses under external loading and under ambient conditions. Where the research literature discusses component or element technology related to performance assessment, this book uniquely covers the subject at the level of the whole system including soil foundation, showing engineers how to model changes in concrete structures over time and how to use this for decision making in infrastructure maintenance and asset management.

Download or read book Recent research developments in food biotechnology written by Raffaele Porta and published by . This book was released on 2008-01-01 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enzymes are highly efficient and naturally occurring catalysts allowing all the biochemical reactions and processes of life to happen. They are present in all food raw materials from both animal and plant origin. Due to the role played by numerous microorganisms in the production of foods and beverages, enzymes have been extensively and unwittingly used in the past centuries. In fact, for many thousands of years man has used naturally occurring microorganisms bacteria, yeasts and moulds and the enzymes they produce to make foods like bread and cheese, or drinks such as beer and wine. The Egyptians and Sumerians (2000 B.C.) developed fermentation for use in brewing and both bread- and cheese-making. Essential in the metabolism of all living organisms, the enzymes can also be used to drive chemical reactions outside their natural localization. When purified and added to food preparations, several enzymes are able to improve their flavor, texture, nutritional value and digestibility. In fact, enzyme efficiency, specificity and environmental friendliness led to their increased use in food processing. Food industry is constantly seeking advanced technologies to meet consumer demand and the enzymes are a useful biotechnological tool whose action can be controlled in the food matrix to prepare high quality products. Moreover, the enzymes facilitate chemical reactions otherwise impossible or requiring conditions that could damage or destroy the end product or which would need a too much high input of energy. Examples are the production of clear apple juice concentrates, which relies on the use of the enzyme pectinase, and the breakdown of starch to sugars. The latter process, originally carried out by boiling the starch with acid and, thus, requiring large energy inputs, takes place in the presence of enzymes in mild conditions, saving energy and preventing pollution of undesirable by-products. However, it was not until the mid of the past century that the rapid development in enzyme technology occurred, and only in the last 30 years the use of commercial enzymes has grown in the food industry, progressively becoming an important aspect of the manufacturing of particular foods, such as meat, vegetables, fruit, baked goods, milk products, and both alcoholic and non-alcoholic beverages. Currently used food enzymes sometimes originate in animals and plants but most come from a range of beneficial microorganisms. Thus, numerous purified enzymes are now being widely used not only in food processing but also as food additives. In this respect, it is noteworthy that the enzymes, like all proteins, can cause reactions only when people have been sensitized through exposure to large quantities. Therefore, since their levels in the food are generally very low, the enzymes are highly unlikely to cause allergies. Finally, the recent advent of biotechnology has also allowed significant refinements in the methodologies offering unpredictable solutions to many persistent problems and opening up exciting new possibilities. Among these, enzymes are proposed as exemplary agents of green technology since they can also be used either to treat biological wastes or to prevent their formation. However, even though the first food application of a product of gene technology (alpha-amylase) took place in 1982, progress in this field is being slowed down because the debate on some other more controversial applications of genetic engineering in animals is continuing throughout Europe. This book highlights the rapidly expanding field of enzyme applications in food technology, explaining how the biocatalysts bring advantages in some food processing improvement and innovation. The properties of different enzymes are linked to the physical and biochemical events that they influence and are related to the key nutritional, organoleptic and shelf-life qualities of food. In this context, the chapters explore also recent developments in the use of some enzymes as well as the discovery of applications of new enzymes.
