Description:	Whey is a highly polluting by-product of cheese processing. However, it has valuable nutritional properties since it is a rich and balanced source of proteins and amino acids. Therefore, it has a broad range of functional properties that can be exploited for diverse applications. Research has shown how the enzymatic hydrolysis of whey proteins releases bioactive peptides. In the present study, the hydrolysis of whey protein concentrate (WCP) was performed using purified Sporisorium reilianum aspartyl protease (Eap1), commercial enzymes chymotrypsin (C) and trypsin (T), as well as different enzymatic combinations in order to determine which enzyme or combination allowed for the release of peptides presenting the highest antioxidant and antihypertensive activity levels; our results indicated that hydrolysis with Eap1 releases the best-performing peptides in comparison with individual enzymes and their combinations. El suero lácteo a pesar de ser considerado un desecho altamente contaminante de la industria quesera cuenta con importantes propiedades nutrimentales, ya que es una fuente rica y equilibrada en aminoácidos que presentan propiedades funcionales que pueden ser aprovechadas. Algunos estudios indican que la hidrólisis enzimática de las proteínas séricas permite liberar péptidos bioactivos. En este estudio se realizó la hidrólisis del concentrado proteico del suero lácteo (WCP) por acción de la aspartil proteasa purificada Sporisorium reilianum (Eap1), las enzimas comerciales quimotripsina (C), tripsina (T) y de la combinación enzimática de estas, con la finalidad de determinar que enzima permite liberar péptidos con mejor actividad antioxidante y antihipertensiva. Los resultados de la actividad biológica indicaron que la Eap1 libera péptidos con mejor actividad en comparación con las enzimas individuales y sus combinaciones.
