Abstract
The current scientific research is focused on the Einkorn flakes of Bulgarian origin. The aim is to determine their moisture adsorption and desorption isotherms. The flakes are obtained of milling Einkorn grains with a reconstructed mill roll. The applied pressure was between 200 and 280 tons. The experimental database of equilibrium moisture content (EMC) are determined at three different temperatures – 10°C, 25°C and 40°C through the standard static gravimetric method in the compulsory presence of water activity within the range from 0.1 to 0.9. The obtained adsorption and desorption isotherms have an S-shape profile i.e. they are from the IInd class typical of the majority of food products. The results confirm a regularity that the sorption capacity decreases with increasing of the temperature in the presence of constant water activity which is valid for the both processes. The mathematical three-parametric modified models of Chung–Pfost, Oswin, Halsey and Henderson are evaluated for the description of the obtained sorption data. The monolayer moisture content (MMC) of Einkorn flakes is calculated through the linearization of Brunauer-Emmett-Teller equation. The values varied from 3.26% to 4.92%.
