The aim of this study was to evaluate the nutritional value of wholemeal bread prepared from the flour of spelt wheat (Triticum aestivum ssp. spelta) that was enriched by the addition of freeze-dried spelt grain (at proportions of 4%, 8%, and 12%, respectively, in relation to the flour weight). The spelt grain used in the study was harvested at the milk dough stage (the so-called green grain). Green spelt grain was characterized by a significantly higher content of minerals namely P, Mg, Ca and Zn compared to ripe spelt grain. Additionally, it contained significantly higher amounts of amino acids (Asp, Thr, Ser, Gly, Ala, Cys, Val, Met, Ile, Leu, Phe, Lys), lipids, as well as monounsaturated fatty acids (MUFA), and omega-3 and omega-9 acids. However, it had a lower content of palmitic, stearic, and linoleic acids, polyunsaturated fatty acids (PUFA), and omega-6 acids. The results showed that the nutritional value of bread was improved by the green spelt grain, however the ω6/ω3 ratio in bread enriched with green spelt grain was slightly less favorable than in control bread. Among all the products tested, bread enriched with a 12% proportion of green spelt grain was characterized by the highest content of almost all the amino acids (except for Pro, Cys, and Met), as well as in Mg, Zn, Mn, Cu and Fe. In addition, overall acceptability of this bread was the highest. Bread enriched with 8% of green grain contained the highest amount of P, Ca, Pro, linoleic acid, PUFA, and ω 6 acids, while bread enriched with 4% of green spelt grain had the highest content of palmitic acid and saturated fatty acids.
