Abstract

This study investigates the spatial distribution of antioxidant activity in baguette and its impact on inflammation. The crust showed higher browning, advanced glycation end products (AGEs), and antioxidant capacity than the crumb, likely due to the Maillard reaction. Both crust and crumb extracts reduced cellular oxidative stress, but the crust was more effective against peroxyl radical-induced membrane hyperpolarization and mitochondrial respiration suppression. Crumb extracts, however, were more potent in inhibiting lipopolysaccharide-induced proinflammatory cytokine expression in macrophages. The findings suggest a complex relationship between baguette components and immune responses.
