Wastewaters from the industrial manufacturing of Argentinus
cuttlefish (Illex argentinus) were kindly provided by Frinova S.A.,
Pescanova Group (Porri ˜no, Galicia, Spain). Four waters corresponding
to thawing (E1), softening (E2), boiling (E3), and gelation (E4)
processes were previously decanted in order to discard the particulate
matter, sampled for analytical determinations and finally
stored at
−18 ◦C until further use.
