Chemical Characteristics and Pasting Properties of Commercial Slovak Common and Spelt Wheat Flours

Th e objective of this paper was to show diff erences among qualitative parameters of commercially produced Slovak fi ne and wholemeal wheat fl ours prepared from Triticum aestivum L. (common wheat) and Triticum aestivum ssp. spelta L. (spelt wheat). Th e selected chemical parameters (protein, starch, ash, glucose, fructose, sucrose, maltose, pH, lactic acid, acetic acid, citric acid, succinic acid, calcium, iron and zinc), gluten characteristics (wet and dry gluten, extensibility of gluten and swelling of gluten) and pasting properties (pasting temperature, peak viscosity, hot paste viscosity, peak viscosity temperature and breakdown value) of fl ours were analysed. Spelt wheat wholemeal fl our produced in ecological system of farming diff ered from other commercially produced wheat fl ours mainly in ash (1.82 %), proteins (16.5 %), wet gluten (43.2 % in dry matter), minerals (Ca, Fe, Zn) and organic acids content. Maltose was found as the most predominate saccharide in the common wheat fi ne fl our (0.46 g/100g) and sucrose was prevalent in common and spelt wheat wholemeal fl ours (0.68 and 0.76 g/100g). It was also stated that commercially produced common wheat fi ne fl our was characterised by lower pasting temperature (59 °C), peak viscosity (575 BU) and breakdown value (210 BU) than common and spelt wheat wholemeal fl ours.
