Abstract: Protein enrichment of bakery products not only improves protein ingestion, but also compensates for the deficiency of certain limiting amino acids in these products. However, the addition of protein sources can greatly influence the characteristics of the dough and, consequently, process and product parameters. Thus, the objective of this work was to evaluate the rheological behavior of wheat flour doughs enriched with whey and collagen protein hydrolysates. Both hydrolysates influenced rheological properties of wheat flour doughs. They reduced water absorption and increased arrival time and dough development time, but caused a weakening of the dough when compared to the control. However, a greater influence of collagen hydrolysate was observed when compared to whey hydrolysate. Regarding pasting properties, the hydrolysates led to a decrease in all parameters, except pasting temperature. These results allow predicting the behavior of doughs enriched with these protein sources during processing and directing their application
