Breadmaking improving quality

Breadmaking © Woodhead Publishing Limited, 2012 Related titles: More baking problems solved (ISBN 978-1-84569-382-4) When things go wrong in the bakery, the pressures of production not allow time for research into the solution Solving these baking problems has always been the province of ‘experts’ However, with a methodical approach, keen observation and a suitable reference book then the answers to many bakery problems are straightforward The companion volume to the popular Baking problems solved, More baking problems solved contains the answers to further frequently asked questions Once again arranged in a practical question-and-answer format, it enables busy bakery professionals to understand causes of their problems and implement solutions It is of invaluable use to all bakery professionals, bakery students, food technologists and product developers Cereal grains (ISBN 978-1-84569-563-7) The quality of cereal products is dependent to a large extent on the suitability of the cereal grains processed Therefore it is essential that cereals producers and handlers understand grain quality requirements for different end uses Grain suppliers and users must also be able to rapidly and accurately assess grain end-use quality and use this information to direct their grain quality management activities This book provides a convenient and comprehensive overview of academic research and industry best practice in these areas Chapters review quality aspects of different cereals and also specific aspects of grain quality analysis and management Technology of functional cereal products (ISBN 978-1-84569-177-6) Cereal grains and their fractions contain many health-protecting compounds, such as phytochemicals, vitamins and indigestible carbohydrates, but the texture and taste of functional cereal products can be less than ideal Technology of functional cereal products reviews technologies for producing a wide range of cereal products with different health-promoting properties and more acceptable sensory quality Introductory chapters summarise the health effects of whole grains and cereal components such as resistant starch The second part of the book focuses on technologies to improve the quality of a wide range of cereal products, such as fortified breads, pasta and products made from non-wheat grains such as oats and rye Details of these
