The study presents assessment of commodity characteristics of grains from ancient varieties of wheat (einkorn, emmer and spelt) in comparison to grains of the conventional wheat cultivar Arkadia. The findings related to the grain of einkorn and emmer were very similar, and far worse than those related to spelt grain; the latter were found with better ratings, sometimes even in comparison to the conventional wheat grain (e.g. the highest mass-weight density). Similar relationships were observed between the flours produced by milling the grains. Analysis of the indirect baking quality indicators showed that flours from einkorn and emmer can effectively be used for baking purposes, however they present low technological value. The flour from emmer wheat was found to be the poorest, which was confirmed e.g. by the low gluten number, gluten index, Zeleny’s index, and high gluten spreadability. Spelt flour was found to present moderate technological value. Based on the results it can be concluded that by using adequate modification in the process of dough kneading and fermentation it will be possible to produce high quality baked goods from ancient wheat grains.
