Abstract

Plant protein concentrates are used to enhance the nutritional quality of bread and to respond to the demand of consumers with respect to increased protein intake. In the present study, bread samples were produced using pea protein concentrate (PP) and soy protein concentrate (SP) substituting wheat flour by 5%, 10%, and 15%. The protein levels were between 1.2- and 1.7-fold (PP) and 1.1- and 1.3-fold (SP) higher than the control bread. The incorporation of 10% and 15% PP allowed for the achievement of a “high protein” claim. Water absorption was correlated with the protein contents of the breads (r = 0.9441). The decrease in bread volume was higher for the PP than SP incorporations, and it was highly negatively correlated with the protein content (r = −0.9356). Soy breads had a softer crumb than pea breads. The total change in crumb colour was higher in the PP than SP breads. The soy breads had an overall acceptability between 6.3 and 6.8, which did not differ (p > 0.05) from the control. PP breads were statistically less liked (p < 0.05). The results underlined that the choice of the type and amount of protein concentrates influenced the bread properties differently.
