Handbook Of Dough Fermentations

Handbook of Dough Fermentations describes the preparation of ferments and utilization of starters in the commercial baking and food industries and offers in-depth discussion on the modification of sourdough processes in the production of common bakery products, as well as the microbiological principles, fermentation pathways, product formulations, and technological methodologies relating to these procedures. This unique reference examines statistical market trends for fermented cereal, yeast, and natural and sourdough products. It pinpoints areas of potential for products and foods using fermentation science and analyzes the application of starters in the production of specific products.

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.

The author's aim in writing this book is to integrate currently available knowledge concerning the basic scientific and technological aspects of breadmaking processes with the diverse breadmaking methods used to manufacture bread in Europe and on the North American continent today. To date, the main technological advances have been in process mechanization, starting with oven development, then dough processing or make-up equipment, followed by continuous and batch mixing techniques from the 1950s to the present time. On the engineering side, universal emphasis is now being placed on the application of high technology, in the form of microprocessors, computer-controlled equipment and robotization, the long-term objective being computer integrated manufacture (CIM) with full automation within the large chain bakery groups in the capitalist countries and the state-run collectives of Eastern Europe. The application of these key technologies with biotechnology, as yet only applied to a limited degree in food manufacture, coupled with advances in biochemical and rheological understanding of dough as a biomass for breadmaking, should provide us with more expertise and ability to control the processes with greater efficiency. The application of fermentable substrates and industrial enzymes under strict kinetic control should contribute to improving the flavour characteristics of bread. Current trends towards improving the nutritional contribution of bread to the daily diet are improving the competitive edge of bread as a basic food in the market-place.

This mini guide helps the home baker to get an overview of the sourdough fermentation process, as well as to begin to use Warwick Quinton's own unique sourdough technique. It is based upon the use of a few simple methods, and differs from more general sourdough recipe books because it explains exactly why and how each of these methods can be combined to create professional quality sourdough bread at home, flexibly and simply.Warwick Quinton has been making artisan sourdough breads professionally for almost thirty years, and was one of the original sourdough bakers in Australia. His method is ideally suited to 'sole' baking - that is, bread baked on the sole of the oven. This method removes the need for bread tins, bannetons and other bits and pieces bakers find themselves accumulating. It also relies on the use of a thickened type of sourdough starter, known as a 'desem'. Of course, the method can be applied to the general use of bread tins and bannetons as well, and will yield better results - that is, a better shape of loaf, more rise, and stronger oven 'kick' than you might have already been getting. The guide covers important parts of the sourdough bread making process, including pre-fermentation, proofing and how to keep your starter in good condition. There is information on what different types of flours do in the fermentation process, as well as how to adapt your baking process to suit different seasons of the year - a common issue among home bakers. There is a simple sourdough recipe to get you started, and useful tips on starter storage.This is the first in a series of mini guides which aim to illuminate and expand the detail of the sourdough process, from dough making, through to proofing and retardation, and sole baking. It is suitable for beginners and advanced bakers alike, with an emphasis on the 'why' as well as the 'how to'. Too many books these days are purely concerned with teaching the reader the details of how to do something, rather than providing decent information which will help a keen student to really get their teeth into the subject matter. Warwick's extensive baking experience, both as a professional master baker and dedicated teacher of home bakers, sets this mini guide apart. The information is both practical and insightful. In a nutshell, his writing about sourdough baking helps beginners and advanced bakers to sort the wheat from the chaff.

Numerous foods are prepared by fermentation processes in which one or more kinds of microorganisms are responsible for the characteristic flavour or texture, and sometimes for the keeping quality of the product. The manufacture of fermented food products is carried out on a small scale in homes in every country. Fermented products are more palatable and are not as easily spoiled as the natural products. The microorganisms that produce the desirable changes may be the natural flora on the material to be fermented, or may be added as starter cultures. The yield of organic acids principally lactic, serve as a preserving agents. Lactic acid fermentation is an anaerobic intramolecular oxidation reduction process. Both homofermentative and heterofermentative lactic acid bacteria participate in food fermentations. In some fermented food products, yeasts and moulds also participate along with lactic acid bacteria. Most of the reactions in living organisms are catalyzed by protein molecules called enzymes. Enzymes can rightly be called the catalytic machinery of living systems. The real break through of enzymes occurred with the introduction of microbial proteases into detergents. Most of the enzymes are produced by microorganisms in submerged cultures in large reactors called fermentors. In choosing the production strain several aspects have to be considered. Industrial enzyme market is growing steadily. The reason for this lies in improved production efficiency resulting in cheaper enzymes, in new application fields. Tailoring enzymes for specific applications will be a future trend with continuously improving tools and understanding of structure-function relationships and increased search for enzymes from exotic environments. This field deals with how are the enzymes used and applied in practical processes. A lot of fungal, bacterial and actinomycete strains with potential for producing novel industrial enzymes have been identified. This book contains sterilization, fermentation processes, aeration and agitation, use of yeast, yeast production, fermentation raw materials, production of bacterial enzymes, bread making methods, effluent treatment, production of actinomycete protease, lactic acid, citric acid. This handbook will be very helpful to its readers who are just beginners in this field and will also find useful for upcoming entrepreneurs, existing industries, food technologist, technical institution etc.
