title: Legume seeds and cereal grains' capacity to accumulate iron while sprouting in order to obtain food fortificant.
abstract: BACKGROUND
  Prepared sprouts, after culturing in a medium with an increased iron concentration, could become a beneficial food iron fortificant. However, the efficient iron accumulation depends on the plants genus, species and/or varieties. The aim of the study was to indicate the seeds or grains which accumulate iron most efficiently during the sprouting process.
  
  
  METHODS
  Alfalfa, lentil, lupine and soybean seeds as well as wheat grains were sprouted in abiotic stress conditions induced by the excess of iron(II) in culture media. The tolerance of these plants to iron concentration and its accumulation in the material obtained (with FAAS method) were analyzed.
  
  
  RESULTS
  The smallest tolerance was noted for lentil seeds and wheat grains. Other plants developed in 25 mM solution of FeSO4. The highest accumulation of iron was observed in alfalfa sprouts. However, lupine and soybean seeds are the most recommended raw material for the production of the sprouts on an industrial scale.
