The distribution of some chemical elements in activated grain raw material

The problem of mineral elements distribution in grain raw material with high fiber content was investigated. Deep pro- cessing of grain, in the first place, assumes fine grinding of grain substrate. In the experiment wheat, barley, oats and grain wastes were milled in a mill and divided into 200-400- 600-800 μm and over 800 μm fineness fractions. Fine fod- der, called "activated", was used: AHF - activated highly en- zymatic grain wastes fodder; AHB - activated highly enzymat- ic barley fodder; AHBF - activated highly enzymatic bran fodder and AHO - activated highly enzymatic oats fodder. The content of the following macroelements was determined in obtained fractions: calcium, phosphorus, magnesium and iron. It was established that, depending on the size of feed particles, the content of the macroelements in them was dif- ferent. The distribution of calcium, phosphorus, magnesium and iron in the fractions of wheat, oats and barley obeys the following regulation: being at the minimum in fine fraction, their content increased with increasing particle size in the range from 400 to 800 microns...
