    Abstract:
    The content of micro/macroelements, lead and cadmium in Faba bean proteins from the seeds after their harvest and from the seeds stored (2 months, 6-8 degrees C) and dried (6h at 35 degrees C up to 15-15% moisture) was determined. Proteins were extracted with water (pH 8.0). Globulins were precipitated from water protein extract at pH 4.2. The microelements (Cu, Mn, Fe and Zn) content in albumins and globulins from the seeds after their harvest and from stored and dried seeds were as follows: 37.4 and 27.1; 46.7 and 35.8; 15.4 and 18.9; 179.2 and 229.7 micrograms/g (albumins) and 24.9 and 31.9; 20.0 and 28.1; 92.1 and 205.4; 68.7 and 102.9 micrograms/g (globulins). These findings indicate that Faba bean albumins and globulins form the labile and neutral nucleo-glycoprotein complexes with Cu, Mn, Fe and Zn. The process of storage and drying caused the migration of the micro and macroelements between albumins and globulins. Generally, one may say that Faba bean albumins and globulins are the source of the biologically active micro- and macroelements.
