The effect of pectin from apple and arabic gum from acacia tree on quality of wheat flour dough

Abstract

The influence of hydrocolloids on the qualitative properties of wheat flour dough was monitored by farinograph. The addition of arabic gum from acacia tree to the dough decreased water absorption and the degree of softening but the development time of the dough increased. The improvement in quality of the doughs occurred only after the addition of 15.0 g.kg-1. The addition of pectin from apple increased water absorption of the dough. Dough stability was increasing until the addition of 5.0 g. kg-1 but then it decreased. The degrees of softening were decreasing until the addition of 5.0 g.kg-1 but then they increased. Farinograph quality number was increasing until the addition of 5.0 g.kg-1 pectin from apple but then it decreased to the value of 149. These hydrocolloids are able to modify different qualitative properties of dough depending on their amount.
