Characteristics of flour and dough from purple and blue wheat grain

Popis výsledku v původním jazyce

The characteristics of flours and doughs prepared from wheat grains containing purple pericarp (variety PS Karkulka and Jumiko) and wheat grain containing blue aleurone (variety Skorpion) were tested and compared with commercial wheat to evaluate the applicability of colored wheat in bread making. The fine flours prepared from colored wheat grains significantly differed in the activity of the amylase enzyme, expressed as Hagberg falling number. Zeleny sedimentation volume of flour prepared from grains of the PS Karkulka variety (36 mL) was significantly higher than the values of AF Jumiko and Skropion (34 mL) varieties. The results of uniaxial deformation test indicated that doughs prepared from wheat varieties PS Karkulka and Skropion can be elongated; the dough is, however, weak and can be expected to rupture more easily than dough prepared from variety AF Jumiko, as well as commercial flour. Even if some variations in the values of farinographic dough development time and stability were also observed, clear differences in the behavior of doughs prepared from colored and commercial flours were not found. The differences in dough behavior during heating test were also negligible. It can be concluded that none of the tested colored wheat grains exhibited characteristics completely different from the others or the commercial one. The results may indicate the applicability of all tested colored wheat grains in yeast-leavened bread production.
