In the last few decades, many efforts have been made to exploit sourdough¿s potential for making baked goods. Through the biotechnology of this traditional baking method, many sensory, rheological, nutritional, and shelf- life properties have been discovered and/or rediscovered. Bakery industries are greatly attracted by the potentials that sourdough presents, and new industrial protocols are being developed. To the best of our knowledge, there has been no single book dedicated to sourdough biotechnology, and which clearly demonstrate its potential. This book aims at defining and highlighting the microbiological, technological, nutritional, and chemical aspects of sourdough biotechnology. The book will be the first reference guide on this
