[Chemical composition of seeds and testa of Vicia faba L].

Different chemical components were analysed in the seeds and in testa of Vicia faba. The seeds contain a relatively high crude protein (27.5%), a low crude fat (3.36%) content; and the lignin concentration is low (2.65%). The testa of the seeds has a very high fibre concentration and is a significant Ca-source (1.86 g/kg). The higher macroelement concentrations in the seeds were measured from K, P and Mg. The main microelements (Fe, Mn, Cu, Zn) have significant higher concentrations in the seed than in the testa. The amino acid composition of seeds is positive (compared to data of white lupine), the rate of essential amino acids is good. The concentrations of the examined antinutritive organic constituents, especially of alkaloids, are low. On the basis of chemical analysis, the production and utilisation of seeds of Vicia faba is recommended.
