Wheat is the world's most important agricultural commodity. In
Europe, where wheat is the main staple, bread wheat (Triticum
aestivum) covers the majority of land on which wheat is cropped.
Wheat breeders and technologists have contributed greatly to the
continued success of bread wheat and its products. The bread-making
quality' of a wheat variety can be described in relation to the
processing its kernels must undergo to make a good bread. Bread
wheat kernels must be suitable for proper milling into a flour that
can produce a dough capable of becoming fine bread. The type of
bread varies depending on local bread-making practices. Part I of
this book contains a study of the anatomy and chemical composition
of wheat kernels, and of the fundamental difference between soft'
and hard' kernelled varieties. It relates these characteristics to
the processes of milling, dough-making and manufacturing of bread,
and to biscuit and pasta making. The genetic basis for these
characteristics is illustrated, and assay methods for
characterizing wheat varieties - ranging from Saunders' chewing
test to the most recent developments in glutenin and gliadin
research - are evaluated. Part II briefly describes - country by
country - how bread-making quality has been integrated into
wheat-breeding programmes throughout Europe, and how breeders have
attempted to resolve the conflict between yield and quality. It
describes how quality wheats travelled' around the world - from
their endogenic source in Eastern Europe to North America, and back
again to Europe. This explains how specific genetic material can
appear in the pedigrees of varieties grown in a wide range of
agro-ecological zones. In addition to givingan interesting
historical survey, the book points the way forward for breeders'
efforts in the future. Bread-Making Quality updates and interprets
knowledge in a way that makes it particularly accessible for food
technologists, breeders, students, and teachers.
Wheat has a long history of serving as an important food crop to
mankind. Especially in the Northern Hemisphere, it has been
appreciated as a major source of energy through its carbohydrates,
and in more recent times for its supply of valuable proteins. This
combination of carbohydrates and proteins gives wheat its unique
properties for making breads of different kinds of tastes. During
the course of history, the quality of wheat has improved stead ily,
undoubtedly for a long time by accident, and for reasons little
under stood. Over the last 150 years our knowledge has increased on
farming and crop husbandry, on bringing about improvements through
goal-oriented plant breeding, and on milling and baking technology,
leading to the standards that we enjoy today. This process will
certainly continue as our knowledge of the genetic reservoir of
wheat species increases. The European Cereal Atlas Foundation
(ECAF) maintains the aim of in creasing and disseminating knowledge
about cereal crops. Within that scope ECAF has decided to publish a
book on the history of bread wheat in Europe, the development of
associated bread-making technology, and the breeding of bread
wheats during the twentieth century. As ECAF is a Dutch foundation,
its Board is particularly pleased to have found three Dutch
scientists willing to contribute to this volume. Two of them have
served wheat science in the Netherlands for their entire scientific
careers, spanning a period starting around 1955 and lasting for
several decades of very productive wheat science development."
