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.

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.

Traditional sourdough bread refers to spontaneous fermentation of cereals by lactic acid bacteria and yeasts, leading to natural selections of microorganisms. The metabolic activity of these microorganisms promotes the formation of organic acids, flavor development and leavening in food matrices, which most know as sourdough bread. This bread is still widely manufactured at farm level across Europe and worldwide, being highly appreciated by consumers for its distinct flavor, texture, healthy attributes and natural origin. Sourdough bread is expected to grow 6.9% annually through 2023. Once stagnant, the bread market has experienced a revival specifically through sourdough bread consumption. Consumers have been avoiding bread in the recent years due to the presence of extra ingredients such as chemical dough conditioners, preservatives and added sugar. However, the increasing popularity of fermented foods and their multiple health benefits are prompting the growth of sourdough market. This fast-growing market has been demanding a dynamic response from industries producing starter cultures to accelerate sourdough fermented bread production in increasing quantities while keeping its “made-for-you” characteristics. By bringing together top sourdough experts in Europe and beyond, this book compiles the latest knowledge in all areas of sourdough starter culture and advantages in using sourdough fermentation. Sourdough Microbiota and Starter Cultures for Industry supplies a biosciences’ audience with a hands on view of the latest advances from sourdough microbiota characterization to starter culture potentials targeting industrial application, including specific techno-functional and safety improvements obtained by clean-labeling strategies. Insights on health and improved quality shed light on new shifting consumer preferences and why choosing sourdough fermentation is a great expansion opportunity in one’s portfolio as the science behind sourdough starter cultures meets improved nutrition-impact opportunities. This text teaches methods to exploit sourdough technology through the entire value chain from sourdough natural microflora through the development of novel starter cultures for producing fermented food, introducing the advantages that sourdough fermentation offers for improving the sensorial, technological and nutritional properties of breads.

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.

Over the past decade, new applications of genetic engineering in the fermentation of food products have received a great deal of coverage in scientific literature. While many books focus solely on recent developments, this reference book highlights these developments and provides detailed background and manufacturing information. Co-Edited by Fidel Toldra - Recipient of the 2010 Distinguished Research Award from the American Meat Science Association Presenting a comprehensive overview, Handbook of Food and Beverage Fermentation Technology examines a wide range of starter cultures and manufacturing procedures for popular alcoholic beverages and bakery, dairy, meat, cereal, soy, and vegetable food products. An international panel of experts from government, industry, and academia provide an in-depth review of fermentation history, microorganisms, quality assurance practices, and manufacturing guidelines. The text focuses on the quality of the final food product, flavor formation, and new advances in starter cultures for dairy fermentations using recent examples that depict the main species used, their characteristics, and their impact on the development of other fermented foods. With approximately 2,300 references for further exploration, this is a valuable resource for food scientists, technologists, microbiologists, toxicologists, and processors.

Sourdough fermentation was probably one of the first microbial processes employed by mankind for the production and preservation of food. This practice is still widely used worldwide due to the distinct sensorial and health properties attributed to these products. Traditional sourdough bread is achieved by spontaneous fermentations, leading to natural selections of microorganisms (mainly yeast and lactic acid bacteria) with health benefits for the consumers’ microbiota. However, multiple opportunities are currently underexploited through the entire sourdough value chain. Sourdough Innovations: Novel Uses of Metabolites, Enzymes, and Microbiota from Sourdough Processing summarizes the latest scientific knowledge and current opportunities of sourdough technology at biomass, microbiota and enzymatic levels described in three distinctive sections. Section I covers the fermentation process of cereals and non-cereals to produce sourdough-containing compounds with health-enhancement benefits. Section II includes novel advances in sourdough enzymology, and last, Section III explores various applications of sourdough microbiota as antimicrobial and probiotic microorganisms and opportunities to be included in both food and non-food applications. Key Features: Includes extensive information on the use of innovative or emerging technologies aiming to promote circular exploitation systems. Promotes the full use of the cereal and non-cereal sourdough metabolites. Covers the functionality of sourdough microorganisms and functional compounds, and future exploitation of some of them in the field of nutraceuticals or functional foods.
