The influence of ground amaranth seeds addition on the baking value of commercial wheat flour


For the tests there were used commercial wheat flour type 650 and 850 and samples of amaranth seeds coming from harvests of 1995 and 1996, supplied by PHU “Szarłat” at Łomża. The amaranth seeds were ground and added to wheat flour at 2 ,4 , 6 and 8%. The addition of amaranth brought about an increase in total protein content. While with 4% addition of amaranth in blend the content of wet gluten, sedimentation value and falling number got decreased. As for rheologic properties of dough, the addition of amaranth was found to have favourably influenced the water absorption of flour and its valorimetric value. Besides, increasing addition of amaranth was bringing about an increase in the initial and terminal temperature of gelatinization as well as in the viscosity of paste. Both the wheat bread and that with addition of amaranth looked properly and their quality was good. Addition of amaranth did not affect the volume nor overbacke of bread, but it was found to have improved the porosity of crumb.
