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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
