AB Bread is a global dietary staple, yet conventional formulations rely on chemical additives for texture, stability, and shelf life, while offering limited nutritional value. This doctoral thesis explores natural alternatives to improve bread quality using unrefined plant ingredients, aligning with growing consumer demand for healthier, additive-free products.Four studies assessed the potential of acerola powder, psyllium husk, and apple pomace as sustainable solutions for bread production, enhancing both its technological and nutritional properties. Acerola powder, rich in ascorbic acid, effectively replaced synthetic oxidants, enhancing dough elasticity and loaf volume. Psyllium husk demonstrated a strong anti-staling effect by modulating water dynamics, improving hydration, and enhancing the texture and sensory properties of whole meal bread. Apple pomace, a by-product of juice and cider production, increased polyphenol content in bread, with exogenous fibers protecting these bioactive compounds during baking while preserving crumb structure and moisture. This research highlights the potential of plant-based ingredients to replace synthetic bread improvers, offering a cleaner-label approach that enhances both technological and nutritional quality without compromising consumer acceptance.
