Actividad inhibidora de la enzima convertidora de la angiotensina de un hidrolizado de lactosuero de cabra con proteasa de Aspergillus oryzae

Abstract

The purpose of this research was to determine the inhibitory activity of the Angiotensin-converting enzyme (ACE) of a goat whey hydrolysate obtained by application of an Aspergillus oryzae protease/peptidase complex (Flavourzyme). Goat cheese whey was hydrolyzed under controlled conditions, considering two variables: whey protein concentration method (ultrafiltration and thermo-coagulation) and inclusion or not of an acid lactic bacteria in the enzymatic treatment. Hydrolysate derived from the combined action of acid lactic bacteria and the protease on the thermo-coagulated whey proteins showed the largest ACE inhibitory activity. It is concluded that this technique might allow using goat whey as a functional ingredient in the prevention of hypertension.
