Abstract
Five Pakistani wheat cultivars namely MH 97, Inqlab 91, Auqab 2000, Iqbal 2000 and Chenab 2000 were milled to obtain different flour mill streams viz. bran & shorts, break 1, break 2, break 3, break 4, sizing, middling, tailing and whole wheat flour. The Kernel weight of wheat cultivars varied from 33.84 to 40.40g (per thousand kernels). Test weight ranged from 69.99 (Iqbal 2000) to 73.00 kg/hL (Chenab 2000) between the wheat cultivars. Chemical components such as moisture, crude protein and total ash were affected siqnificantly by mill streams as well as by the wheat cultivars. The mineral contents were found significantly higher in bran & shorts followed by whole wheat flour. Iron content ranged from 97.90 to 124.50 mg/kg among different flour mill streams. Zinc content varied from 30.50 to 94.93 mg/kg. Manganese content was higher in bran & shorts and the lowest was found in sizing fraction and ranged from 90.90 to 92.26 mg/kg among different flour mill streams. Copper content ranged from 6.30 to 15.90 mg/kg while Cadmium content was only found in bran & shorts and whole wheat flour i.e. 4.20 and 1.50 mg/kg respectively. Key Words: Wheat cultivars, flour mill streams, iron, manganese, copper, cadmium, zinc
