Abstract:

Rheological characteristics were studied of brown flour type 1250, from Romanian wheat. The effect of hydrotermally treated potato on the rheological properties of flour dough was investigated. Haubelt Flourgraph E6 was used to determine water absorption in dough investigated with Haubelt Flourgraph E7. Flourgraph E7 resistance to extension significantly increased with the addition of potato pulp in time. The maxim value obtained at 90 minutes for sample control. The values of resistance to extension were best correlated with the percentage replacement of flour with potato at 45, 90 and 135 minutes. The brown flour additives, premix additive because the correlation is not so good.

Keywords:

dough, rheological properties, wheat brown flour, potato pulp.
