Influence of vegetable protein isolates on structural and mechanical properties of wheat dough

Abstract

The influence of soya’s, pea’s and rice’s isolates on the structural and mechanical properties of wheat dough. Dough’s’ farinogram are explored with the addition of 20% of the isolates showed that all samples bind more water than the control: the least – with the addition of rice protein isolate (5% more over the control), the most - soya’s isolate (32% more over the control). We calculated that the addition of 1 g of isolate of soya requires in additional 2.2 g of water, 1 g of protein isolate of peas – 1.4 g of water and 1 g of rice protein isolate – 1.2 g of water.
