Abstract


In recent years many studies have shown that brewers spent grain (BSG), the major by-product of the brewing industry, is no longer regarded as waste but rather as a rich source of bioactive compounds. With a hypothesis that this by-product could be efficiently valorized in developing new added-value food products this study evaluates the content of BSG in several bioactive compounds and assessed their influence on enhancing the nutritional quality of a basic snack composition. The substitution of wheat flour with 10%, 20% and 30% ground BSG led to development of three breadsticks formulations with increased nutritional value (protein, fiber, lipid and minerals) and enhanced antioxidant properties, in a dose dependent manner. Also, the sensorial analysis revealed that, compare with a control sample, the prototype with 10% and 20% BSG had good organoleptic attributes and overall acceptability. The obtained results emphasize the great opportunity to reuse this by-product in developing innovative added-value food products.
