Abstract
Numerous worldwide studies have shown that there is a difference in the
mineral composition between organically and conventionally produced plants
and their products. Spelt (Triticum spelta), alternative grain from the family
Poaceae, occupies a very important place in the production of healthy food.
Also, spelt represents commonly grown organic crops due to the ideally
balanced ratio of nutrients. In addition to the macroelements, for the survival
and normal plant function some microelements are also needed. The aim of
this study was to determine the existence of differences in the content of
microelements and (B, Ba, Cu, Li, Mn and Se) in organically and
conventionally produced spelt seeds, in period of 2015-2017. The
determination of these elements was conducted by using Inductively Coupled
Plasma Optical Emission Spectrometry (ICP-OES) with previous digestion of
samples and results were expressed as mg/kg of dry weight. In samples
collected during 2015 and 2016, B and Ba were not detected. In conventional
spelt seed, higher quantity of Ba (2.366 mg/kg), Cu (6.356 mg/kg) and Mn
(55.878 mg/kg) was determined, while organic spelt seed contained higher
content of B (0.875 mg/kg), Li (14.77 mg/kg) and Se (0.275 mg/kg) compared
to conventionally grown sample. The obtained results for the examined
elements revealed that the lowest content in analyzed seeds was for Li
(conventional seed from 2017, 0,008 mg/kg), while Mn was quantified in the
highest amount (conventional seed from 2017, 55.878 mg/kg)
