world where nished our does not undergo any treatment. This would most likely be true where quality is not considered particularlycritical. This situation may exist in many underdeveloped regions of the world. Even insuch cases, our imported or received as part of an aid package may contain vitaminsand minerals. The following section describes each of these objectives in more detail. 3.4.1.1 Enrichment As shown in Fig. 2, endosperm makes up about 8% of wheat kernel; however, it contains, relative to the whole kernel of wheat, only small portion of the importantvitamins (Table . 3 Sarkar Fig. 3 Neutral position.

In the pursuit of the production of the white rened our, many of the nutrients are lost with the removed bran and germ fractions. In North America, it is common practice, therefore, to enrich the our with these vitamins and some minerals. In Canada,however, our must be enriched to prescribed level according to the federal law (Ta-ble . There are number of countries that would require the addition of the foregoing enrichments, however, to varying degrees there are certain special needs that may require the use of specic vitamins or minerals. For example, in the United Kingdom, the supple- mentation of calcium is required by law. This necessitates the addition of calcium carbon-ate in the our. 3.4.1.2 Enhancement of Flour Appearance The presence of ne bran particles and our streams from the bran end (low-grade) have not only deleterious effect on the functionality of the our, but also have an adverse effect on the our appearance in terms of dress (bran specks) and color. Furthermore, within given variety of wheat, the higher the our extraction rate, the greater will bepolyphenol oxidase enzyme levels (Hatcher and Kruger, . Polyphenol oxidase hasa darkening eff
