CHAPTER ONE

1.0 INTRODUCTION

Despite many years of investigation, it has not been possible to determine accurately when and where the first cultivated wheat originated. At the beginning of recorded history, wheat was already an established crop whose origin was unknown (Anon 1953). There is however some evidence that cultivation of wheat started about 6,000 years ago in the 5yria – Palestine area and spread to Egypt, (ran, India, China, Russia, Turkey and Central Europe from where it spread to other countries and continents. Countries that produce wheat today include Russia, Switzer land United State of America, Belgium, Canada, Denmark, England, Poland, Netherlands, Norway, Swedan, South Africa, Peru, Australia, Argentina, Chile, Newzealand and Nigeria. 9Shellenberger, 1969, Olugbemi etal 1992).

 

In addition, wheat flour has uniques properties that differs it from other flours in containing a considerable proportion of gluten which makes wheat flour suitable for bread making and other bake products. This composition of gluten present has a bearing on the “strength” and water holding properties of the flour. The two protein that form the greater part of the guten are gluternin and gliadin while the latter appear to be identical in strong and weak wheat, the former exists in different varieties.
