This work
focuses
on the production
of antihypertensive
and antioxidant activities
using enzymatic
hydrolysis
of protein concentrates
recovered
by ultrafiltration
of different wastewaters
from the industrial
processing
of cuttlefish (Illex argentinus).
The effluents
were produced in the processes
of thawing(E1),
softening (E2),
boiling (E3)
and gelation (E4).

Thereby,
UF-fractionation
followed
by proteolysis of protein concentrates from cuttlefish wastewaters
offers new opportunities for the development of bioactive hydrolysates with application in the food
industry. In addition, this approach contributes to an improved depuration of industrial wastewaters,
reducing the treatment costs and leading to a decrease in its contaminating effect.
