The utilization of food industry by-products represents a significant opportunity for developing functional foods. This study investigated the incorporation of Cucurbita maxima Plomo peel powder (PS) into wheat bread formulations to assess its potential as a valuable ingredient for bread-making. PS was incorporated into wheat flour at 1%, 10%, and 20% levels. The dough’s rheological properties were analyzed using Mixolab. Bread samples were evaluated for physical characteristics (volume, texture, colour), antioxidant properties (DPPH, ABTS, FRAP), and reducing sugar content. Analyses were performed on day 0 and after 7 days of storage. PS incorporation significantly modified dough rheology, with increased development time and enhanced protein stability. Bread volume decreased progressively with PS addition (from 195.5 cm3 to 109.8 cm3 at 20% PS). However, antioxidant activity increased substantially, particularly in the crust, with ABTS values rising from 2.37 to 10.08 TE μM/g DM in water extracts. Total phenolic content and reducing sugars showed significant increases across all PS concentrations. Storage studies revealed stable antioxidant properties but progressive textural changes, with hardness increasing from 6.83 N to 108.8 N at 20% PS after 7 days. While PS incorporation affects bread’s physical properties, the significant enhancement in antioxidant activity and phenolic content suggests its potential as a functional ingredient. The optimal incorporation level should balance technological properties with nutritional benefits.
